Contributors netapp-jolieg NetAppZacharyWambold

Before you add, upgrade, or replace a host interface card (HIC) in an E5700, review the requirements and considerations.

Procedure overview

You can add, upgrade, or replace a HIC in the E5724 controller shelf and the E5760 controller shelf.

The following is an overview of the steps to replace a HIC in an E5700 controllers (E5724 or E5760):

  1. Take the controller offline

  2. Remove the controller canister

  3. Replace the battery

  4. Replace the controller canister

  5. Bring the controller online

Requirements for adding, upgrading or replacing a HIC

If you plan to add, upgrade, or replace a host interface card (HIC), keep the following requirements in mind.

  • You must schedule a downtime maintenance window for this procedure. The power must be off when you install HICs, so you cannot access data on the storage array until you have successfully completed this procedure. (In a duplex configuration, this is because both controllers must have the same HIC configuration when they are powered on.)

  • You must have two HICs that are compatible with your controllers.

    For duplex configurations (two controllers), the HICs installed in the two controller canisters must be identical. 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.

    For information about compatible hardware, refer to the NetApp Interoperability Matrix or the NetApp Hardware Universe.

  • 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.

  • You have a management station with a browser that can access SANtricity System Manager for the controller. (To open the System Manager interface, point the browser to the controller’s domain name or IP address.)
