Chapter 7. Host interface cards
7.1. Requirements for DE6400 or DE6600 HIC upgrades
Before upgrading or replacing a host interface card (HIC) in a DE6400 or
DE6600 array, review the following requirements.
• You have scheduled a downtime maintenance window for this procedure. You cannot access
data on the storage array until you have successfully completed this procedure. Because both
controllers must have the same HIC configuration when they are powered on, the power must
be off when you change HIC configuration. The presence of mismatched HICs causes the
controller with the replacement HIC to lock down when you bring it online.
• You have all cables, transceivers, switches, and host bus adapters (HBAs) needed to connect
the new host ports.

• You have an ESD wristband, or you have taken other antistatic precautions.
• You have a #1 Phillips screwdriver.
• You have labels to identify each cable that is connected to the controller canister.
• A management station with a browser that can access ThinkSystem System Manager for the
controller. (To open the System Manager interface, point the browser to the controller's domain
name or IP address.)
• Some HIC replacements or upgrades might require a host port protocol conversion. Follow the
instructions in the
Change host protocol for a DE6400 or DE6600
• DE6400 controllers must have HIC port 2 filled with a HIC for host connectivity.
7.2. Upgrade DE6400 or DE6600 host interface card (HIC)
You can upgrade the host interface cards (HICs) to increase the number of host
ports or to change host protocols.
About this task
• When you upgrade HICs, you must power off the storage array, upgrade the HICs, and reapply
power.
• When upgrading HICs in a DE6400 or DE6600 controller repeat all steps to remove the second
controller, upgrade the second controller's HICs, and reinstall the second controller before
reapplying power to the controller shelf.
