C H A P T E R 5 - Removing and Replacing Miscellaneous Internal Components

2. Remove the server cover.

3. Open the rotating service module.

4. Ensure that the server is properly grounded.

5. Determine if you want to gain access to the components beneath the air duct and rear fan assembly, or if you want to completely remove the assembly from the server (refer to FIGURE 5-1 for both sets of instructions).

If you want to gain access to components beneath the air duct and rear fan assembly, push the tab on the right of the assembly to the rear of the system, then rotate it up and out of the way.

If you want to completely remove the air duct and rear fan assembly from the server:

a. Push the tab on the right of the assembly to the rear of the assembly and rotate the assembly up.

b. Unplug the two lower cables from the system board.

c. Dislodge the assembly from the rear supports and slide it out of the system.

FIGURE 5-1 Removing/Rotating the Air Duct and Rear Fan Assembly

This figure is in two parts. The first figure shows how to rotate the air duct and rear fan assembly into an upright position. The second figure shows how to remove the assembly from the system board.

Installing or Closing the Air Duct and Rear Fan Assembly

1. Slide the air duct and rear fan assembly into position.

2. Plug in the two lower cables from the system board (FIGURE 5-1).

3. Rotate the assembly back in position and press down to snap the locking tab.

4. Close the rotating service module.

5. Install the server cover.

6. Power on the server.

Memory Modules

There are eight DIMM slots on the system board, with four DIMM slots adjacent to each CPU socket. Because memory is installed as matched DIMM pairs, these slots are divided into two DIMM banks per CPU (see FIGURE 5-2 for their locations).

Therefore, CPU0 has four corresponding DIMM slots divided into two banks, Bank0 and Bank1. CPU1 has four corresponding DIMM slots divided into two banks, Bank0 and Bank1.

FIGURE 5-2 System Board CPUs and Corresponding Memory Locations

This is a figure of the system board layout. It calls out CPU0 and CPU1 and shows the locations of the corresponding DIMM banks.

Memory is available in DIMM pairs. For a list of the available memory options, see Miscellaneous Internal Components.

To install one or more new memory modules in your server, go to Installing Memory Modules.

To replace faulty memory modules in the server, first go to Removing Memory Modules to remove the faulty memory module(s), then go to Installing Memory Modules to install the replacement memory module(s).

Removing Memory Modules

1. Power off the server.

2. Remove the server cover.

3. Open the rotating service module.

4. Ensure that the server is properly grounded.

5. Rotate the air duct and rear fan assembly up.

See Removing or Rotating the Air Duct and Rear Fan Assembly. Note that you only have to rotate the assembly up, not remove it from the server.

6. Press down on the latches at the sides of the memory socket (FIGURE 5-3).

FIGURE 5-3 Removing and Inserting Memory

This figure shows the location of the memory slots. It shows an enlarged view of a memory module and a memory socket.

7. Remove the memory module from the socket.

Installing Memory Modules

Memory Configuration Rules

When you install memory, follow these configuration rules:

All memory must be installed on the system board as matched DIMM pairs, where each DIMM in the pair shares the same characteristics.

All DIMM pairs on the system board must share the following characteristics:

Vendor

Type

Capacity

Speed

On a single-processor system board, install the first DIMM pair in the memory bank next to the CPU. For example, on a single-processor system board, the CPU is installed in the CPU0 slot. Therefore, you must install the first DIMM pair in CPU0 DIMM Bank0 (see FIGURE 5-2).

A dual-processor system board must have a minimum of one DIMM pair installed in CPU0 DIMM Bank0 (see FIGURE 5-2).

When installing additional memory, see TABLE 5-1 and TABLE 5-2 for the proper installation order of the DIMM pairs.

TABLE 5-1 DIMM Pair Installation Order for a Single-Processor Server
DIMM Pair	System Board DIMM Bank
First DIMM pair	CPU0 DIMM Bank0
Second DIMM pair	CPU0 DIMM Bank1

TABLE 5-2 DIMM Pair Installation Order for a Dual-Processor Server
DIMM Pair	System Board DIMM Bank
First DIMM pair	CPU0 DIMM Bank0
Second DIMM pair	CPU1 DIMM Bank0
Third DIMM pair	CPU0 DIMM Bank1
Fourth DIMM pair	CPU1 DIMM Bank1

PCI Cards

The Netra 240 server supports one full-length 64-bit PCI card running at 33 MHz or 66 MHz (PCI0), and two half-length 64-bit PCI cards running at 33 MHz (PCI1 and PCI2). They are 3.3V (PCI 0) and 5V (PCI 1-2). The server can support a maximum of 25W per card, but no more than 45W spread over all three slots. The PCI cards are not hot-swappable.

Note - Add PCI cards to the Netra 240 server in order from PCI 0 to PCI 2. This corresponds to populating the PCI slots from bottom to top.

The following procedures describe how to remove and install individual PCI cards into the Netra 240 server.

To install one or more new PCI cards in your server, go to Installing a PCI Card.

To replace a faulty PCI card in the server, first go to Removing a PCI Card to remove the PCI card, then go to Installing a PCI Card to install the replacement PCI card.

FIGURE 5-6 Removing and Installing the Upper Half-Length PCI Cards

This figure calls out the upper half-length PCI cards for removal.

If you are removing the full-size PCI card at the lowest position (PCI0), follow these instructions:

FIGURE 5-7 Removing and Installing the Lower Full-Length PCI Card

This figure calls out the PCI card support and the lower full-length PCI card that it supports.

b. Unseat the PCI card from the connector and lift it out of the server (FIGURE 5-7).

Power Distribution Board

The power distribution board distributes power to the components in the Netra 240 server.

Removing the Power Distribution Board

1. Power off the server.

2. Disconnect the power input cables from both power supply units.

3. Remove the server cover.

4. Open the rotating service module.

5. Ensure that the server is properly grounded.

6. Disconnect the power distribution board wiring harness from the three connectors on the system board (FIGURE 5-8).

FIGURE 5-8 Removing the Power Distribution Board

This figure shows the cables and connectors to be detached during the removal of the power distribution board.

7. Disconnect the power distribution board cable from the SCSI interface board (FIGURE 5-8).

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.

8. Pull the lever on the back of each power supply unit down (FIGURE 5-9).

4. Connect the power distribution board wiring harness to the three connectors on the system board (FIGURE 5-8).

5. Insert the two power supply units in the power supply unit bays.

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

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 returns to vertical, the power supply unit does not engage correctly.

7. Press the lever up on each power supply unit until it clicks.

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

8. Close the rotating service module.

9. Install the server cover.
