IP131 Compute Blade Status LEDs

88
Each IP131 compute blade installed in an enclosure has status LED indicators arranged in a single
row behind the perforated sheetmetal of the blade. The LEDs are located in the front lower section
of the compute blade and are visible through the screen of the compute blade, see Figure 6-5.

The functions of the IP131 blade LED status lights are as follows:
1. UID - Unit identifier - this blue LED is used during troubleshooting to find a specific
compute node. The LED can be lit via software to aid in locating a specific compute blade.
2. CPU Power OK - this green LED lights when the correct power levels are present on the
processor(s).
3. IB0 link - green LED lights when a link is established on the internal InfiniBand 0 port.
4. IB0 active - this amber LED flashes when IB0 is active (transmitting data).
5. IB1 link - green LED lights when a link is established on the internal InfiniBand 1 port.
6. IB1 active - this amber LED flashes when IB1 is active (transmitting data).
7. Eth1 link - this green LED is illuminated when a link as been established on the system
control Eth1 port.
8. Eth1 active - this amber LED flashes when Eth1 is active (transmitting data).
9. BMC heartbeat - this green LED flashes when the blade's BMC boots and is running
normally. No illumination, or an LED that stays on solidly indicates the BMC failed.
