5. Using two hands and the cam handle, slide the controller canister out of the shelf.
Attention: Always use two hands to support the weight of a controller canister.
If you are removing the controller canister from an E5724 controller shelf, a flap swings into
place to block the empty bay, helping to maintain air flow and cooling.

Step 2: Install host interface card
You install the host interface card (HIC) to increase the number of host ports in your storage array.
Before you begin
• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a #1 Phillips screwdriver.
• You have one or two HICs, based on whether you have one or two controllers in your storage
array. The HICs must be compatible with your controllers.
About this task
Attention: Possible loss of data access – Never install a HIC in an E5700 controller canister if
that HIC was designed for another E-Series controller. In addition, if you have a duplex
configuration, both controllers and both HICs must be identical. The presence of incompatible or
mismatched HICs will cause the controllers to lock down when you apply power.
