  FIGURE 3-3 Removing and Replacing the Air Filter From the Bezel

This figure shows the open bezel and the air filter.

Installing the Air Filter

1. Snap the new air filter into place in the bezel (FIGURE 3-3).

2. Close the bezel.

System Configuration Card

The system configuration card (SCC) ships tied in place to prevent the card from getting lost. The SCC contains a server's unique network identity information, including the MAC address and host ID (stored in the IDPROM), and the OpenBoot PROM configuration (also known as NVRAM). For more on the NVRAM, see Appendix C.

You can use the procedures in this section to either replace a faulty SCC or to swap a server's unique configuration information from one server to another.

If the system configuration card is faulty or lost, a replacement card can be obtained from Sun Services. See Appendix A for the system configuration card part number. For more information on how to contact Sun Services, read the Netra 240 Server Release Notes (817-3142).

The replacement system configuration card is not programmed with any OpenBoot PROM and ALOM configurations. Upon initial insertion in the Netra 240 server, you are prompted for confirmation that you wish to use the new card. It is then configured with the default configuration for the server.


caution icon

Caution - The system configuration card must be installed and in place at all times while the system is running. If you remove a system configuration card while the system is running, the system powers off within 30 seconds.



caution icon

Caution - Avoid contact with the gold terminals on the underside of the card.



caution icon

Caution - Never remove the system configuration card while the server is booting or running the Solaris software. Before removing or inserting the system configuration card, remove power from the server, or put it into Standby mode.


Removing a System Configuration Card

1. Power off the server.

See Powering Off the Server. If you are swapping configuration information from one server to another, you must power off both servers before proceeding.

2. Open the front bezel (FIGURE 3-1).

3. Cut and remove the tie wrap that secures the system configuration card, and remove the card from the system configuration card reader (FIGURE 3-4).


Note - Once the system configuration card is inserted into the system configuration card reader, secure a new tie wrap to discourage accidental or unintentional removal of the card.


  FIGURE 3-4 Removing and Inserting a System Configuration Card

This figure shows the system configuration card and the location of the system configuration card reader. It also shows a magnified view of the tie wrap which is used to secure the card in place.

Inserting a System Configuration Card

1. Insert the system configuration card into the system configuration card reader (FIGURE 3-4).

2. Replace the tie wrap on the card.


Note - By replacing the tie wrap, you ensure that the system configuration card is properly seated in the card reader (see FIGURE 3-4). If the card projects out of the card reader, the system does not boot properly. The tie wrap discourages accidental or unintentional removal of the system configuration card.


3. Power on the server(s).

See Powering On the Server.


caution icon

Caution - Never remove the system configuration card while the server is booting or running the Solaris software. Before removing or inserting the system configuration card, either remove power from the server, or put it into Standby mode.fs


Hard Drives

The Netra 240 server has slots for up to two internal hard drives. The slots accept any Sun Low Voltage Differential (LVD) SCSI hard drive conforming to the 1-inch SCA-2 form factor.


Note - If a Netra 240 server uses one hard drive only, ensure that the filler panel is fitted in the other hard drive bay. The server must not run without a filler in the unoccupied hard drive bay. If you remove the hard drive slot filler panel, retain it for future use.


Removing a Hard Drive

If you are removing a hard drive while the operating system is still running, you must remove the drive logically from the operating system before physically removing it from the server. If you are removing a hard drive from a server that is powered off, skip to Step 6 in these procedures.

Use the following instructions in conjunction with the cfgadm(M) man page.

1. Check that the hard drive you want to remove is visible to the operating system.

caution icon

Caution - Before proceeding, you must remove the hard drive from all its software mount positions and delete any swap areas in use on the disk. If the drive is the system boot device, do not proceed further with these instructions. Do not attempt to unconfigure the boot disk.


3. Unconfigure the hard drive that you intend to remove.

Use the unconfigure command and specify the device you intend to remove. For example, if it is Disk 1, type: 

# cfgadm -c unconfigure c1::dsk/c1t1d0

4. Check that the device is now unconfigured: 

# cfgadm -al

Ap_Id           Type        Receptacle Occupant      Condition

7. Grip the bezel at the two finger holds and rotate it down to open (FIGURE 3-1).

8. Check that the blue indicator LED is lit on the hard drive.

The blue LED comes on when the hard drive is ready to remove. See FIGURE 1-6 for the location of the LED indicators for the hard drive.

9. Slide the catch at the front of the hard drive to the right (FIGURE 3-5).

  FIGURE 3-5 Removing and Installing a Hard Drive

This figure shows details of the hard drive during installation or removal. It calls out the drive catch and the drive handle.

10. Pull the handle and remove the hard drive from the server by sliding it out from its bay.

Installing a Hard Drive

1. Slide the catch on the front of the hard drive to the right (FIGURE 3-5).

This releases the handle on the front of the hard drive. The lever must be open before you insert the hard drive into the server. If the lever is closed, the hard drive will not engage with the server correctly.

2. Slide the hard drive into its bay at the front of the server.

Push the drive in firmly until the metal lever starts to close. This indicates that the hard drive has engaged with its connector in the server.

3. Push the metal lever until the drive clicks into place.

4. Close the bezel.

5. Determine if the server is powered off or not.

6. Log into the system as superuser and run the format command so that the drive is visible to the operating system.

Power Supply Unit

The Netra 240 server has dual redundant power supplies. You can hot-swap one power supply while the other is still running, without having to power off the server.


caution icon

Caution - The power supplies contain pinch points. Be very careful when opening and closing the levers on the power supplies. Keep your hands and fingers away from the base and sides of the levers. For more information about these pinch points, refer to the power supply labels.


Removing a Power Supply Unit

1. At the ALOM prompt, type: 

sc> removefru -y PSn

Where n is the power supply unit identifier (1 or 2). For example, to replace power supply unit 1, you would enter: 

sc> removefru -y PS1

When the blue OK to Remove LED on the back of the power supply unit lights up, you can safely remove the unit. See FIGURE 1-7 for the location of the LED indicators for the power supply unit.

2. Disconnect the power input cable from the power supply unit being replaced.


caution icon

Caution - Do not remove the power input cable from the remaining power supply unit. Doing so causes the system to go through an immediate ungraceful shutdown.


3. Pull the lever on the back of the power supply unit down (FIGURE 3-8).

This disconnects the power supply unit from the power distribution board inside the server.

  FIGURE 3-8 Removing a Power Supply Unit

This figure shows one of the two power supply units being removed from the server. It calls out the lever on the back of the unit.

4. Slide the power supply unit out of the server chassis by pulling on the lever (FIGURE 3-8).

Installing a Power Supply Unit

1. Insert the power supply unit in the power supply unit bay.

2. Slide the power supply unit into the server until you feel it engage with the power distribution board inside.

Ensure that the lever does not return to a vertical position until the power supply unit engages with the power distribution board. If the lever is vertical, the power supply unit does not engage correctly.

3. Press the lever up until it clicks.

Returning the lever to a vertical position engages the power supply unit with the power distribution board inside the server.

4. At the ALOM prompt, type: 

sc> poweron PSn

Where n is the power supply unit identifier (0 or 1). For example, to power on power supply unit 1, you would type: 

sc> poweron PS1

5. Use the power supply unit LED indicators to verify that the power supply unit is up and running.

The green LED on the back of the power supply unit should light up, indicating that the power supply unit is functioning properly. See FIGURE 1-7 for the location of the LED indicators for the power supply unit. If the green LED on the back of the power supply unit does not light up, repeat Step 1 to Step 5.
