Installing or replacing expansion adapters

About installing or replacing expansion adapters

Replacing an expansion adapter or installing a new expansion adapter consists of one or both of the following procedures:

Expansion adapters used

The storage engine uses the following expansion adapters:

NVRAM4 adapter
FC-AL adapter for disk storage
Network interface cards
Tape adapters:
- SCSI
- FC-AL

Slot assignments for expansion adapters

If you are adding expansion adapters to your storage engine, the System Configuration Guide at http://now.netapp.com provides current configuration information for the following:

Expansion slots that are available on your storage engine
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 storage engine from Network Appliance or an authorized reseller.

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	Unlatch the PCI clamp arm and pull it aside. Note Your system might require that you screw down PCI expansion adapters. If so, remove and set aside any screws for PCI expansion adapters.
3	Note which cables (if any) are connected to the connectors on the faceplate of the expansion adapter before disconnecting the cables.
4	If you are replacing...	Then...
	The NVRAM4 adapter	Remove the PCB carrier crossbar by loosening the thumbscrew and lifting the crossbar away from the top of the PCB carrier. Caution If you did not perform a clean shutdown using the `halt` command, disconnecting the NVRAM battery from the NVRAM4 adapter results in data loss.
	Any other PCI adapter	Go to Step 5.
5	Remove the PCI clamp-down bracket holding the expansion adapter faceplate to the back panel bracket and save it for reinstalling the adapter.
6	Pull upward on the top edge of the expansion adapter and lift it out of the chassis, as shown.
7	If you are...	Then...
	Not installing a replacement expansion adapter	Install a slot cover for the empty PCI slot.
	Installing a replacement expansion adapter	Go to Installing an expansion adapter.

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	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.
3	Press carefully on the top edge of the adapter until the edge connector is seated in the expansion slot.
4	If applicable, replace the faceplate screw to secure the adapter to the back panel.
5	Reconnect the cables to the external connectors on the replacement expansion adapter.
6	If you are...	Then...
	Replacing the NVRAM4	Lock down the PCB carrier crossbar over the NVRAM4, and then secure the crossbar to the side of the PCB carrier by tightening the thumbscrew.
	Replacing a an adapter other the NVRAM4	Go to Step 7.
7	Go to Closing the PCB carrier
8	After turning on the storage engine, run diagnostics on the expansion adapter you replaced. See the Diagnostics Guide for more information.
