Rack power and cooling LED indicators (Model 983)

This section contains storage system power and cooling FRUs that have LED indicators. Each listed assembly is shown with a description of its LEDs. Although LED indicators might indicate a failure, do not use them as a starting point for a repair. Display and repair related open serviceable events.

Notes:
  1. Off under any of the following conditions:
    • The UPS does not have output power on.
    • The corresponding RPC is fenced.
    • The LED is broken
  2. On solid when the UPS outputs are on.
  3. Flashes slow (1 flash per 2 seconds) when a DC-UPS is not fenced, or the Remote Force Power Off switch is active.
    Flashes rapidly (2 flashes per second) during the DC-UPS power ON, power OFF, and Force Power OFF sequences.
  4. Lit solid indicates Attention status, which means that one or more open serviceable events that need repair exist. When all serviceable events are closed or canceled, the LED changes to off.
  5. When both attention and identify status exist on the system, the identify indication is shown and the LED flashes.

 2  Network connection status Green

Off

Not connected to a network

On

Network connection established and the IPv4 address is usable.

 Flashes slowly (every 500 ms): Faulty IP address.
 2  Linking status between the SNMP IPv6 and the UPS Yellow N/A N/A
  • Flashes rapidly (every 50 ms): UPS linked.
  • Flashes slowly (every 500 ms): UPS not linked.
 2  Status of SNMP IPv6 initializing or upgrading firmware.

The two LED indicators flash simultaneously to show its status.

 N/A N/A N/A
  • Rapid simultaneous flashing (every 50 ms) - Initialization or firmware upgrade in progress.
  • Slow simultaneous flashing (every 500 ms) - Initialization failed.
