Upgrade Host Interface Card - Fujitsu ETERNUS AB Series Maintaining Hardware

Upgrade host interface card

You upgrade a host interface card (HIC) to increase the number of host ports or to change host protocols. If you
are upgrading HICs in a duplex configuration, repeat all steps to remove the other controller canister, remove
the HIC, install the new HIC, and replace the second controller canister.
Remove controller canister
You remove the controller canister so you can upgrade the new host interface card (HIC). When you remove
a controller canister, you must disconnect all cables. Then, you can slide the controller canister out of the
controller shelf.
Before you begin
• You have labels to identify each cable that is connected to the controller canister.
• You have an ESD wristband, or you have taken other antistatic precautions.
Procedure
1. Label each cable that is attached to the controller canister.
2. Disconnect all the cables from the controller canister.
Attention: To prevent degraded performance, do not twist, fold, pinch, or step on the cables.
3. If the HIC ports use SFP+ transceivers, remove them.
Depending on what type of HIC you are upgrading to, you might be able to reuse these SFPs.
4. Confirm that the Cache Active LED on the back of the controller is off.
The green Cache Active LED on the back of the controller is on when cached data needs to be written to the
drives. You must wait for this LED to turn off before removing the controller canister.

5. Squeeze the latch on the cam handle until it releases, and then open the cam handle to the right to
release the controller canister from the shelf.
