External Components
This section describes the external components that are located on the front and rear
panels of the IX-brick.
Front Panel Components
The IX-brick has the following front-panel components (see Figure 4-4):
•
Two SCSI disk drives.
These customer-removable, sled-mounted SCSI disk drives
are used to store your operating system and other application software. (See
“Installing or Replacing Disk Drives in IX-brick” on page 211) for instructions for
installing or removing the SCSI disk drives.
•
DVD-ROM device.
This device loads software onto your IX-brick. (It is used for
text reading only in CD-ROM mode.)
•
L1 controller display.
This liquid crystal display (LCD) displays status and error
messages that the L1 controller generates.
Note:
For more information about the L1 controller, see the
SGI L1 and L2 Controller
Software User’s Guide
.
•
On/Off switch with LED.
Press this button to turn on the internal components of
the IX-brick. Alternatively, you can turn on the internal components at the L2
controller touch display or at a system console.
•
LEDs:
–
On/Off switch LED.
This green LED illuminates when 48-VDC power is
applied to the internal components of the IX-brick.
–
Service required LED.
This LED illuminates yellow to indicate that a
component is broken or is not operating properly (for example, if a fan is off),
but the IX-brick is still operating.
–
Failure LED.
This LED illuminates red to indicate that a system failure has
occurred and the IX-brick is not operating.
•
Fans.
Three hot-swappable fans provide the required cooling for your IX-brick.
