The following figures show an E5760 controller shelf before and after a HIC upgrade. The two HICs
in the first figure have four SFP+ (optical) host ports, and the two HICs in the second figure have four
SAS ports.
Note: The figures show example controller canisters with example HICs. You might have different
types and numbers of baseboard ports and HIC ports.
Replace HIC
When you replace a failed host interface card (HIC) in an E5700 controller shelf, you must remove
the controller canister, replace the HIC, and reinstall the controller canister. The following figure
shows an E5724 controller shelf with two controller canisters, each with a HIC.
