This section describes the external components on the front and rear panels of the
NUMAlink module.
The NUMAlink module contains the following front panel items (see Figure 5-2):
•
L1 display. The L1 display is a 55.7 mm x 32 mm backlit liquid crystal display
(LCD) that displays system messages. It displays two lines with a maximum of 12
characters on each line.
Note: See the SGI L1 and L2 Controller Software User's Guide (007-3938-00x) for more
information about the L1 controller.
•
On/Off switch with LED. Press this button to turn on the NUMAlink module
internal components. You can also turn on the NUMAlink module internal
components at a system console.
•
Three LEDs:
•
On/Off switch LED. This LED illuminates green when the NUMAlink module
internal components are on and turns off when they are off.
•
Service-required LED. This LED illuminates orange to indicate that an item is
broken or not operating properly (for example, a fan is off), but the NUMAlink
module is still operating.
•
Failure LED. This LED illuminates red to indicate that a system failure has
occurred and the NUMAlink module is down.
•
Fans. Two hot-pluggable fans provide N+1 redundant cooling.
