Rear panel LED state descriptions

The NVRAM, power, and server status LEDs indicate whether the server is powered, its operational state, and whether the NVRAM is currently being protected by battery backup power. The way an LED flashes provides further information about what is currently occurring.

NVRAM status LED (green/amber)
State Meaning
Green (solid) Normal operation
Green (flashing) NVRAM contents are protected by battery power
Amber (solid) Battery pack is faulty or not fitted
Off Disabled or NVRAM battery power exhausted

Power status LED (green)
LEDs Meaning
Green Normal operation with a single server or an active cluster node in operation.
Slow flash (once every three seconds) The system has been shut down.
Medium flash (once every .8 seconds) The server is available to host file services but is not currently doing so. Also if no EVS is configured or all EVSs are running on the other node in a cluster.
Fast flash (five flashes per second) The server is rebooting.
Off The server is not powered up.
Server status LED (amber)
LEDs Meaning
Amber Critical failure and the server is not operational.
Slow flash (once every three seconds) System shutdown has failed. Flashes once every three seconds.
Medium flash (once every .8 seconds) The server needs attention, and a non-critical failure has been detected, for example, a fan or power supply has failed. Flashes once every .8 seconds.
Off Normal operation.

10 Gigabit Ethernet cluster interconnect ports

The 10 gigabit per second Ethernet (10 GbE) cluster ports allow you to connect cluster nodes together. The cluster ports are used only in a cluster configuration. The 10 GbE ports operate at speeds of ten (10) gigabits per second.

Do not use the 10 GbE cluster interconnect ports to connect to the customer data network (also known as the public data network).

Once connected, each 10 GbE port has two indicator LEDs; one green and one amber. These LEDs provide link status and network activity status information as follows:

Status/Activity (per port) Meaning
Status Green

(on, not flashing)

10 Gbps link present
Green flashing 10 Gbps link standby in a redundant configuration
Green off No link
Activity Amber flashing Network activity
Amber off No network activity
