Fibre Channel host interface adapter ports and indicators

If you specified Fibre Channel host interface adapters for your Storwize® V7000 Gen2 or Storwize V7000 Gen2+ system, the adapters are preinstalled in each node canister.

Each 8 Gbps Fibre Channel 4-port host interface adapter (feature code ACHK) can have from two to four short wave (SW) small form-factor pluggable (SFP) transceivers installed. Cap unused ports with safety caps.

Fibre Channel host interface adapter ports

Fibre Channel ports 1 are in 1 - 4 order, starting at the top. Ports and their indicators are shown in Figure 1.

Each port can have up to an 8 Gbps SW SFP transceiver installed. Each transceiver connects to a host or Fibre Channel switch with an LC-to-LC Fibre Channel cable.

Fibre Channel host interface adapter indicators

Each Fibre Channel port has two green LED indicators. The link-state LED 2 is above the speed-state LED 3 for each port. Consider the LEDs as a pair to determine the overall link state, which is decoded in Table 1.

Table 1. Fibre Channel host interface adapter port-state LEDs
Link-state LED	Speed-state LED	Link state
OFF	OFF	Inactive
ON or FLASHING	OFF	Active low speed (2 Gbps)
ON or FLASHING	FLASHING	Active medium speed (4 Gbps)
ON or FLASHING	ON	Active high speed (8 Gbps)

One or two Fibre Channel interface adapters can be installed in each node canister. They can be installed in slots 2 and 3 of the node canister. When a single interface adapter is installed in either slot 2 or slot 3, the Fibre Channel ports on the adapter are numbered 1, 2, 3, and 4.
