Tape adapters
- SCSI
- FC-AL
IB cluster adapter

Slot assignments for expansion adapters

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

Expansion slots that are available on your appliance
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 filer 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. Caution Do not disconnect or connect SCSI cables while your appliance is on. You could cause permanent damage to the hardware.
4	If you are replacing the...	Then...
	NVRAM 4 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 NVRAM 4 adapter results in data loss.
	Remote administration card	Carefully unplug the internal cable that connects to the motherboard.
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	Reinstalling all other adapters	Go to Step 4. 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	If applicable, 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.
7	If you are...	Then...
	Replacing the NVRAM 4	Lock down the PCB carrier crossbar over the NVRAM 4, then secure the crossbar to the side of the PCB carrier by tightening the thumbscrew.
	Replacing the remote management card	Remove the connector from the motherboard, as shown in the following illustration.

8	Go to Closing the PCB carrier.
9	After turning on your appliance, run diagnostics on the expansion adapter you replaced. See the Diagnostics Guide for more information.
