2.7.1 Installing Memory Modules

The CP2140 can accommodate both single- and double-wide memory modules. FIGURE 2-4 shows two typical memory modules used on the Netra CP2140 board.

 FIGURE 2-4 Single- and Double-wide Memory Modules

Up to two modules in any supported memory configuration can be installed in any combination (512 Mbyte, 1 Gbyte). However, if two memory modules need to be installed and one of the modules is double-wide, the double-wide module should be installed first (on the bottom). Refer to Section 3.1.2, Main Memory for a list of possible memory module configurations.

FIGURE 2-5 shows a typical SDRAM memory module installed on a CP2140.

2.8 Configuring Transition Card Hardware

This section provides information on installing PIM assemblies and replacing the Serial EEPROM.

2.8.1 Installing PIM Assemblies

Refer to the user documentation from the PIM manufacturer on how to install the PIM module.

2.8.2 Replacing the Serial EEPROM

This device is installed on the motherboard at the factory. This step is not necessary unless you are installing a replacement board that does not have the host ID. If you must return the CP2140 to the factory, remove this EEPROM from the board before shipping it to the factory. The Serial I²C EEPROM is the MAC address carrier and it stores the backup copy of the board MAC address and host ID information (see Section 5.1.3.4, Serial I2C EEPROM).

 FIGURE 2-7 Replacing the Serial I2C EEPROM

The CP2140 supports the Serial I²C EEPROM. If you must replace the CP2140, remove the Serial I²C EEPROM from the original board and install it on the new CP2140.

To correctly position the EEPROM and to precisely install it on the CP2140, see FIGURE 2-7.

2.9 Installing the XCP2040-TRN I/O Transition Card

Refer to the installation procedure detailed in the XCP2040-TRN I/O Transition Card Manual for Netra CP2040/CP2140 CompactPCI Board (806-6743-xx) for installing the XCP2040-TRN Transition Card.

---

2.10 Installing the Netra CP2140 Board

Follow all the safety rules described in Section 2.4, Safety when installing any hardware into the CompactPCI chassis enclosure.

A number of CompactPCI chassis enclosures come with an internal power supply and fan. FIGURE 2-8 shows two Netra CP2140 boards (system host and satellite host) being installed in a CompactPCI chassis.

Smaller CompactPCI enclosures have four board slots. One of these slots is reserved for one 6U form factor board, while the remaining three slots are for either 3U or 6U boards. The larger eight-slot enclosures have two 6U and six 3U slots. In addition, some special CompactPCI enclosures are equipped with a backplane that enables board connection to the front and rear of the chassis.

A CompactPCI chassis contains:

• A system slot, usually on the far left (viewed from the front) whose position is indicated by a triangle symbol visible on the backplane (if the chassis meets the PICMG 2.0 CompactPCI Specification).
• Seven peripheral slots (for a single-segment chassis). Peripheral slots are identified by a circle symbol visible on the backplane.

---

Note - The CP2140 can be installed in either a peripheral slot or in a system slot.

---

1. Ensure that power is disconnected from the chassis.

The CP2140 can be installed while the chassis is powered-on--however, this method is recommended only when absolutely necessary.

2. Check that the corresponding XCP2040-TRN I/O Transition Card is installed.

Install the transition card before installing the Netra CP2140 board. This step is important if the chassis is powered-on during the installation. The transition card is not hot-swappable. Take the step as a safety precaution.

3. Slide the CP2140 into the appropriate slot on the corresponding top and bottom mounting rails and towards the backplane while gently keeping the board handles pushed inward (see FIGURE 2-8 and FIGURE 2-9).

While pushing the board, ensure that the CP2140 extraction levers are aligned perpendicular to the card flange in the unlocked position and that the board connectors are aligned with the transition card connectors.

4. Install two screws at the top and bottom of the front connector plate to secure the board.

 FIGURE 2-8 Netra CP2140 Board System Interface: One System Controller Board, One Satellite Board, Two Transition Cards

 FIGURE 2-9 Netra CP2140 Board Installation (Close-up View)

The transition card can also be fitted with IHV-supplied PCI interface modules (PIMs) which are configured to bring I/O channels to the unit rear panel. A unit of PIM hardware is a kit that includes a card for the PMC slot and a card for the PIM slot on the transition card. A PIM is essentially a rear-panel extension added to a PMC module.

---

Note - If the PMC card (used with the PIM) has front I/O connectors, when you configure PIM rear connector I/O, the front I/O connectors will not be functional.

---

You can order the XCP2040-TRN Transition Card, build a compatible custom card, or buy from an IHV. A minimal set of I/O must provide for a boot path for the host board and a path for console I/O to deliver commands and to read board and system status.

---

2.11 Connecting Cables to the Netra CP2140 Board

This section describes how to connect cables to a computer that contains the CP2140.

1. Connect the Ethernet (if required) where shown in FIGURE 2-3.

2. Use the tip utility on the host system to establish a full-duplex terminal connection with the system containing a CP2140.

3. At the UNIX® prompt in a command tool or shell tool, type:

tip -9600 /dev/ttya

4. Connect a serial cable to Port A (COM port) on the CP2140 or TTYA port of the XCP2040-TRN I/O Transition Card of the target system and to the serial port of the host system.

---

Note - Use shielded cables that are grounded at both ends for serial and USB ports.

---

5. Connect any other peripheral devices (such as a printer) to the appropriate connector.

6. Power on the system that contains the CP2140 to run the power-on self-tests (POST).

• If POST is successful, install the appropriate Solaris software package on the system (see Section 2.15, Software Installation).
• Read the following caution carefully before plugging devices into the
  XCP2040-TRN I/O Transition Card.

---

Caution - There are a total of three serial port connections available (one on the CP2140 and two on the XCP2040-TRN I/O Transition Card). At any one time, up to two serial ports can be used. The serial port connector (TTYA) on the XCP2040-TRN I/O Transition Card and the serial interface on the CP2140 cannot be used at the same time.

---

7. Plug devices into the XCP2040-TRN I/O Transition Card, as necessary.

See XCP2040-TRN I/O Transition Card Manual for Netra CP2040/CP2140 CompactPCI Board (806-6743-xx) for instructions.

2.11.1 Powering on Your System With External SCSI Peripherals

If you have connected SCSI peripherals that receive power from a source separate than the system's power supply to a system containing a Netra CP2140 board, you must power on the system prior to powering on SCSI peripherals. After powering on the system, you can safely power on the external SCSI peripherals.

---

2.12 Hot-Swapping the Netra CP2140 Board

---

Note - If the CP2140 is being used as system host and not functioning as an I/O card, it cannot be hot-swapped.

---

A blue LED is lit on a hot-swappable board during extraction process to indicate that it is permissible to extract the board. The blue LED indicates that the system software has been placed in a state for an orderly removal of a board.

During the insertion process, when a board is hot inserted, the blue removal LED is lit again automatically by the system hardware until the hardware connection process is complete. The blue LED is turned off by the software until it indicates once again that the removal of a board is permitted.

Two ejector handles are used for inserting and removing a CompactPCI board. The lower ejector handle is tied to a latch, which when pressed, informs the system that the board is ready for extraction. When the system has unconfigured the board, a blue LED is lit indicating that the board is ready for extraction. You must wait until the blue LED is lit before removing the board.

2.12.1 Basic Hot-Swapping

The basic hot swap is initiated by the cfgadm configure/unconfigure administration command:

The cfgadm command provides configuration administration operations on dynamically reconfigurable hardware resources. Configuration administration is performed at attachment points, places where system software supports dynamic reconfiguration of hardware resources during continued operation of the Solaris operating environment.

Configuration administration distinguishes between hardware resources that are physically present in the server and hardware resources that are configured and visible to the Solaris software. The nature of configuration administration functions are hardware-specific and are performed by calling hardware-specific libraries. Refer to the man pages (by typing man cfgadm) for additional information on the options associated with this command.

1. Type the unconfiguration command:

# cfgadm -c unconfigure pci1:hsc0_slot5

To inform the system to enable the extraction and insertion of a device, if permissible. The blue LED is lit if the process is successful, indicating that the board can be extracted.

2. Remove the I/O board and set it aside.

3. Slide the new I/O board into the top and bottom mounting rails in the same slot into the backplane while gently keeping the board handles in the open position. Once the board is all the way in, lock the ejector handles (see FIGURE 2-10).

The blue LED is lit once the board makes complete contact with the backplane. The LED goes off shortly after the ejector handles are closed, if the hardware initialization of the board is successful. Otherwise, it remains lit, indicating that the board must be replaced.

4. Once the blue LED of the board is off, secure the board to the chassis.

5. Type the configuration command:

# cfgadm -c configure pci1:hsc0_<slot5>

The part of the command in parenthesis indicates the slot in which the board resides.

6. Take any other step necessary for board-specific configuration.

2.12.2 Full Hot-Swapping

Hot-swapping a line card does not require the system power to be turned off. Refer to the chassis manufacturer's documentation for slot assignments and additional information. In addition, a full hot-swap board does not require running the cfgadm administrative command. The system automatically configures the card for using the system resources. The board-specific configuration steps are still necessary after the completion of host-specific configuration.

Follow these steps to hot-swap a line card in a chassis that contains the Netra CP2140 system host board.

1. Remove the I/O board screws.

2. Release the latches of the I/O board and wait for the blue LED to light.

3. Remove the I/O board and set it aside.

4. Slide the new I/O board into the top and bottom mounting rails in the same slot into the backplane while gently keeping the board handles in the open position. Once the board is all the way in, lock the ejector handles (see FIGURE 2-10).

FIGURE 2-10 shows how to release and to lock the CP2140 injector/ejector handles.

The blue LED is lit once the board makes a complete contact with the backplane. The LED goes off shortly after the ejector handles are closed, if the hardware initialization of the board is successful. Otherwise, it remains lit, indicating that the board must be replaced.

5. Once the blue LED of the board is off, install two screws at the top and bottom of the front connector plate to secure the board.

• Two USB ports
• Two TTY ports
• Two Ethernet ports
• Two SCSI ports
• KB (PS/2 keyboard)
• KB (PS/2 mouse)
• FLOPPY
• PARALLEL
• PIM

Install the XCP2040-TRN I/O Transition Card as directed in the transition card manual.

---

Note - To comply with NEBS Level 3 Intrabuilding Lightning Surge Tests (Telecommunications Port), the intrabuilding cabling must be shielded and the shield must be grounded at both ends. Refer to GR-1089-CORE, Section 4.5.9.

---

1. Connect a single-ended SCSI drive and cable to the internal SCSI connector on the XCP2040-TRN I/O Transition Card.

The internal SCSI connector is more suitable for attaching internal devices to the system.

---

Caution - For SCSI A, both internal and external SCSI connectors are on the same SCSI A bus. Use only one connector at a time to avoid signal problems on the SCSI chain. Also, the SCSI cable cannot exceed more than 9 feet (3 meters) in length to avoid possible data errors.

---

2. Connect other supported peripheral devices as required.

---

Note - For a detailed description of the XCP2040-TRN I/O Transition Card, refer to XCP2040-TRN I/O Transition Card Manual for Netra CP2040/CP2140 CompactPCI Board (806-6743-xx).

---

2.13.1 Adding CompactPCI Cards and Drivers to a Netra CP2140 Board System

The CP2140 configuration supports IHV CompactPCI cards. To add CompactPCI cards and drivers, refer to the documentation provided with the CompactPCI card. Usually software drivers and related documentation are provided on the CD or floppy diskettes. Read all documentation furnished with the package. The manufacturer's Web site might also have the latest product and driver information.

2.13.1.1 To Install a CompactPCI Card

1. Halt the operating environment and power down the system.

2. Install the CompactPCI card.

3. Make necessary connections.

4. Power up the system.

5. Boot with -r option (or with -rv for verbose messages).

6. At system prompt, become superuser.

7. Add package using pkgadd command.

8. Reboot if necessary.

---

Note - In a properly configured system, a card can be hot inserted and then manually configured by unsing cfgadm.

---

2.13.1.2 To Verify That the Board is Recognized by the System

1. Use the prtconf -D command to display the device tree.

It should show the PCI bus instances #0 and #1 for the two PCI buses on the CP2140. There are instances of various PCI cards connected to each one. A PCI card might show up as pciVVVV,DDDD, where VVVV is the vendor ID, for example, 1011 and DDDD is the device ID, for example 008e. If the driver for the card is already loaded, then you might see the device name supplied by the driver in the device tree.

2. Use the modinfo command to see whether the driver for the card is loaded.

Typically the description of the driver contains the name of the product or the vendor.

3. At the OpenBoot PROM prompt, the PCI board is visible in the device tree even if the driver is not installed.

2.13.1.3 To Obtain Additional Assistance

1. Run the following commands and record the output.

prtconf modinfo dmesg cat /etc/driver_aliasescat /etc/path_to_inst 

2. Contact the PCI card vendor.

2.13.2 Backplane and Cardcage Considerations

To successfully run a Netra CP2140 board system, consider the following points related to the CompactPCI backplane and cardcage:

• For CompactPCI connector information see Appendix A.
• Power supply requirements for backplane and cardcage (for more details see Chapter 3.)
• Cooling fan requirement.
• Overtemperature conditions.
• Shock and vibration standards (see Section 3.1.7, Compliance).

---

ok .version

For details on output information, see Section 6.6, Determining Firmware Version.

---

2.15 Software Installation

The CP2140 requires the Solaris 8 2/02 operating environment software. CP2000 Supplemental CD 4.0 for Solaris 8 is available that offers additional features for the CP2140 such as CompactPCI net driver support and satellite hot-swap support. CP2000 Supplemental CD 3.1 for Solaris 8 can also be used with the Netra CP2140 board, but does not contain all of the features available on CD 4.0.

For further information on how to obtain the CD, contact your Field Application Engineer.

• To install the system from the CD , go to Step 1.
• To install the system from a network, go to Step 2.

1. To install the system from the CD , at the ok prompt, enter:

ok boot cdrom

The system boots from the CD and the Solaris operating environment installation begins. Provide appropriate answers to various prompts that are displayed as the system is installed.

2. To install the system from a server, obtain the boot client Ethernet address (the system being built).

a. At the ok prompt (on the system being built), type:

ok banner

The Ethernet address displayed in the following format: X:X:XX:XX:XX:XX for example: 8:0:20:7e:f6:dc

b. Type the Ethernet address obtained in Step a into the install server as a boot client.

Refer to the Solaris software documentation to set up an install server.

c. At the ok prompt on the client (of the system being built), type:

ok boot net

The system boots from the network and the Solaris software is installed from the network. Various prompts are displayed as the system is installed; answer them as appropriate.

3. After the Solaris operating environment is installed, at the ok prompt, enter:

ok boot disk -rv

The system configures itself after the installation.

If the installation is successful, the system boots to a Solaris login prompt.

---

2.16 Setting Up a Network

The minimal necessary infrastructure to enable network computing involves a boot server with networking software and the CP2140. The boot server senses the CP2140 booting up on the network and supplies the client with its boot image: Solaris software.

---

Note - The Netra CP2140 board also depends on a domain network server (DNS) and a network information server (NIS); do not attempt to set up clients on a network without them.

---

An administrator can also choose a separate Internet Message Access Protocol version 4 (IMAP4) server and a home directory server. These software services can be installed on a single server or spread out over several servers.

Follow these guidelines to help ensure a successful CP2140 client/server configuration.

• Install the CP2140 clients on the same subnet as the boot server. You cannot boot across a gateway or router. The CP2140 boot process uses a Trivial File Transfer Protocol (TFTP) broadcast to receive a secondary boot program called inetboot.jd from the server. Messages using TFTP are automatically disabled as a security measure in routers. The boot process might be changed in future product releases to enable booting across routers. Application or Web servers do not have to be on the same subnet and can be accessed across a router or gateway.
• Do not configure a CP2140 to more than one boot server. You cannot have multiple boot servers attached to the same client.
• Avoid using the UNIX command-line interface to set up the client/server network. Use the available client configuration tools from the WebTop Server software environment. The configuration tools have an easy-to-use graphical user interface (GUI).

---

2.17 Standalone Operation

The CP2140 provides a complete I/O subsystem and can operate as a standalone computer for development purposes or other special applications. The CP2140 provides two UltraWide single-ended SCSI connections that are accessible through the rear of a special CompactPCI chassis that contains a backplane. This enables connection to a hard drive, tape, or a number of other SCSI devices. Software can be downloaded through the internet or from a CD into a hard drive connected to the XCP2040-TRN I/O Transition Card.
