Installing or replacing expansion adapters

About installing or replacing expansion adapters

This section describes the steps involved in replacing an expansion adapter or installing a new expansion adapter. Replacing an expansion adapter consists of the following procedures:

Additional procedures

The NVRAM adapter might also require the following additional procedures:

Expansion adapters used

The GF825 gateway uses the following expansion adapters:

NVRAM III adapter
Dual-port Fibre Channel HBA
Tape adapters
- SCSI
- FC-AL
IB cluster adapter
NICs
DAFS network adapter

Slot assignments for expansion adapters

If you are adding expansion adapters to your gateway, check current system configuration information for the following:

Expansion slots that are available on your gateway
Supported adapters
Expansion slot assignments
Caution
Install only supported expansion adapters in the assigned expansion slots.

Removing an existing expansion adapter

To remove existing expansion adapters, complete the following steps.

Step	Action
1	Open the PCB carrier. Follow the procedure in Opening the PCB carrier.
2	Note which cables (if any) are connected to the connectors on the faceplate of the expansion adapter before disconnecting the cables. Caution Do not disconnect or connect SCSI cables while your gateway is powered up. You could cause permanent damage to the hardware.
3	If you are replacing the...	Then...
	NVRAM III adapter or replacing the DIMM on the NVRAM III adapter	Unplug the electrical wires from the J1 connector on the NVRAM III adapter. See the figure in Replacing the NVRAM III battery. Caution If you did not perform a clean shutdown using the `halt` command, disconnecting the NVRAM battery from the NVRAM III adapter results in data loss.
	Fibre Channel adapter for tape library	Some versions of this adapter might have a GBIC module. Press the latches on both sides of the HSSDC port of the GBIC module and remove the module. This enables you to remove the adapter without difficulty.
	IB cluster or DAFS network adapter	Go to Step 4.
4	Remove the screw holding the expansion adapter faceplate to the back panel bracket and save both for reinstalling the adapter.
5	Pull upward on the top edge of the expansion adapter and lift it out of the chassis, as shown.
6	If you are...	Then...
	Not installing a replacement expansion adapter	Install a faceplate over the empty slot.
	Installing a replacement expansion adapter	Go to Installing an expansion adapter.
	Replacing the DIMM on the NVRAM adapter	Go to Replacing the NVRAM III battery.

Installing an expansion adapter

To install an expansion adapter, complete the following steps.

Step	Action
1	If you are...	Then...
	Installing a new adapter	Take the adapter out of the antistatic bag and discard the bag.
	Installing a replacement adapter	Take the replacement adapter out of the antistatic bag and place the used adapter into that bag.
2	If you are...	Then...
	Replacing or reinstalling an NVRAM III adapter	Plug the electrical wires from the NVRAM battery to the connector on the NVRAM III adapter. See the figure in Replacing the NVRAM III battery.
	Replacing an FC-AL adapter	If your adapter has a GBIC, press the latches on both sides of the HSSDC port of the GBIC module and remove the module. Note The dual channel adapter does not have a GBIC module. Skip this step and go to Step 3. Go to Step 3.
	Reinstalling all other adapters	Go to Step 3. You reinstall adapters when you replace the motherboard.
3	Holding the adapter by its top edge, with the faceplate near the back of the machine, lower the adapter into the slot until its connector edge meets the grooves in the expansion slot. The faceplate of the adapter should be in position against the back panel, and should cover the endplate slot on the back panel.
4	Press carefully on the top edge of the adapter until the edge connector is seated in the expansion slot.
5	Replace the faceplate screw to secure the adapter to the back panel.
6	Reconnect the cables to the external connectors on the replacement expansion adapter. If your replacement adapter requires a GBIC module, plug it into the socket of adapter.
7	Go to Closing the PCB carrier.
