Fibre Channel host interface adapter ports and indicators
Optional Fibre Channel host interface adapters can be added to the Storwize® V3700 node canisters.
The optional 8 Gbps Fibre Channel 4-port host interface adapter (feature code ACHK) can
be installed in a node canister. The adapter can have from two to four short wave (SW) small
form-factor pluggable (SFP) transceivers installed.
Fibre Channel host interface adapter ports
The Fibre Channel ports 1 are numbered 1 - 4, starting from the left. Each port can have an 8 Gbps SW SFP installed; the adapter can have from two to four SFPs installed. The SFPs are connected to hosts or Fibre Channel switches using LC-LC fiber cables.

Fibre Channel host interface adapter indicators
Each Fibre Channel port has two green LED indicators. The Link State LED 2 is on the left and the Speed State LED 3 is on the right. The LEDs must be considered as a pair to determine the link state.
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) |
