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:

Removing an existing expansion adapter
Installing an expansion adapter

Additional procedures

The NVRAM adapter might also require the following additional procedures:

Removing the NVRAM III DIMM
Installing the NVRAM III DIMM

Expansion adapters used

The R100 chassis uses the following expansion adapters:

NVRAM III adapter
SCSI LVD 1080 for disk storage
Tape adapters
- SCSI
- FC-AL
Network interface cards

Where to get current configuration information

The System Configuration Guide at http://now.netapp.com provides current configuration information for the following:

Expansion slots that are available on the chassis
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 the chassis 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	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 the chassis is powered up. You could cause permanent damage to the hardware.
3	If you are replacing...	Then...
	The 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.
	The FC-AL adapter for tape	Press the latches on both sides of the HSSDC port of the GBIC module and remove the module, if one is present. 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 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.
	Installing the DIMM on the NVRAM adapter	Go to Installing 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 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.
	Reinstalling all other adapters	Go to Step 3.
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.
7	Go to Closing the PCB carrier.

Removing the NVRAM III DIMM

To remove the NVRAM III DIMM, complete the following steps.

Note
This procedure assumes that you already removed the NVRAM III adapter, as described in Removing an existing expansion adapter.

Step	Action
1	Push apart the latches on both sides of the DIMM with your index fingers.
2	Place the DIMM in an antistatic bag.

Installing the NVRAM III DIMM

To install the NVRAM III DIMM, complete the following steps.

Step	Action
1	Hold the DIMM at the top corners to avoid damaging the components or the edge connector.
2	Align the DIMM over the slot and then tilt the top edge of the DIMM at a slight angle away from the top edge of the NVRAM adapter.
3	Insert the DIMM into the slot. The DIMM should slide into the slot easily if you wiggle the DIMM into position. If not, realign the DIMM with the slot and try again.
4	Push the DIMM into the slot until the mounting tabs close over the DIMM to lock it in place. Caution Visually inspect the DIMM to verify that it is evenly aligned and fully inserted into the slot; otherwise, the DIMM could bend or break when pushed to the locked position.
5	Return to Installing an expansion adapter to complete the installation.
