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 is the only adapter that might require the following additional procedures:

Expansion adapters used

The C3100/C6100 series NetCache appliances use the following expansion adapters:

NVRAM adapter
Fibre Channel adapters
NICs
Note
The C3100/C6100 Series Hardware Guide lists the supported network interface cards.

Slot assignments for expansion adapters

If you are adding expansion adapters to your C3100/C6100 series NetCache appliance, the System Configuration Guide at http://now.netapp.com provides current configuration information for the following information:

Expansion slots that are available on your C3100/C6100
Supported adapters
Expansion slot assignments
Caution
Install only supported expansion adapters in the assigned expansion slots. To ensure compatibility, performance, and reliability, you must obtain expansion adapters for your C3100/C6100 from Network Appliance or an authorized reseller.

Removing an existing expansion adapter

To remove an existing expansion adapter, 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.
3	If you are replacing...	Then...
	The NVRAM adapter or replacing the DIMM on the NVRAM adapter	Unplug the electrical wires from the J1 connector on the NVRAM 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.
	The FC-AL adapter for disk storage	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.
4	Remove the screw holding the expansion adapter faceplate to the back panel bracket and save it 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 the expansion adapter you removed is an FC-AL adapter, plug the GBIC module of the adapter back into the socket.
7	If you are...	Then...
	Not installing a replacement expansion adapter	Install a slot cover using the screw you saved in Step 4.
	Installing a replacement expansion adapter	Go to Installing an expansion adapter.
	Replacing the DIMM on the NVRAM adapter	Go to Replacing the NVRAM III DIMM.

Installing an expansion adapter

To install an expansion adapter, complete the following steps.

Step	Action
1	If you are...	Then...
	Installing any 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 III battery to the connector on the NVRAM III adapter.
	Replacing an FC-AL adapter	Press the latches on both sides of the HSSDC port of the GBIC module and remove the module. 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	If the expansion adapter you replaced is an FC-AL adapter, plug the GBIC module of the adapter back into the socket.
7	Reconnect the cables to the external connectors on the replacement expansion adapter.
8	Go to Closing the PCB carrier.
