Fibre Channel ports and indicators

If you specified Fibre Channel adapters for your system, the adapters are preinstalled in each node canister.

Each 4-port Fibre Channel can have from two to four short wave (SW) small form-factor pluggable (SFP) transceivers installed. Cap unused ports with safety caps.

Fibre Channel adapter ports

Fibre Channel ports 1 are in 1 - 4 order, starting from the left. Ports and their indicators are displayed below.

Each port can have up to a 16 Gbps SW SFP transceiver installed. Each transceiver connects to a host or Fibre Channel switch with an LC-to-LC Fibre Channel cable.

Figure 1. Fibre Channel ports and indicators

1 Fibre Channel 16 Gbps ports (x4)
2 Link-state LED (x4 - one for each port)
3 Speed-state LED (x4 - one for each port)

For additional information about how port numbers differ on the top and bottom canister, see Connections for control enclosures.

Fibre Channel adapter indicators

Each Fibre Channel port has two green LED indicators. Consider the LEDs as a pair to determine the overall link state, which is described in the following table.

The following table lists the link status values for the Fibre Channel LEDs.

Table 1. Link status values for Fibre Channel LEDs
Green LED	Amber LED	Meaning
Off	Off	One of the following situations is in effect: The port is not configured in flex hardware. The port is not active in the current profile. For example, in a 2 x 16 Gb profile, 2 ports are inactive.
Off	On	The port is configured, but the link is not detected at the transport layer. This situation is the result of the port not being connected or of a failed link negotiation with the switch.
On	Off	The link is up and running at the expected port speed. This display does not necessarily imply logical connectivity, that is, completion of FLOGI or FIP.
On	On	The link is up, but running at a degraded speed.
