IP133 Compute Blade Status LEDs

007-5806-004
Figure 6-6 shows the location and identifies the status LEDs visible through the perforated front
grill of the IP133 compute blade. The blade consists of an interfaced lower and upper node board.

The function of the LED status lights (see Figure 6-6) on the lower node board are as follows:
1. UID - Unit identifier (lower node) - 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 compute node.
2. CPU Power Good (lower node) - this green LED is illuminated when the correct power
levels are present on the processor(s).
3. IB0 link (lower node) - this green LED is illuminated when a link has been established on the
internal InfiniBand 0 port.
4. IB0 active (lower node) - this amber LED flashes when IB0 is active (transmitting data).
5. Eth1 link (lower node)- this green LED is illuminated when a link has been established on
the system control Ethernet port.
6. Eth1 active (lower node) - this amber LED flashes when Eth1 is active (transmitting data).
7. BMC Heartbeat (lower node) - this green LED flashes when the node board's BMC is
functioning normally.
