3: Cx-brick
External Components
The Cx-brick is a 4U-high brick that contains the following front-panel items (see
Figure 3-3):
•
L1 display
is a 2-line by 12-character liquid crystal display (LCD) that displays
status and error messages that the L1 controller generates.
•
On/Off button with LED
enables you to manually power on and power off the
Cx-brick.
•
LEDs:
•
On/Off button LED
illuminates green when the internal components are
powered on.
•
Service required LED
illuminates orange to indicate that an item is not
functioning properly (for example, a fan is off), but the Cx-brick is still
operating.
•
Failure LED
illuminates red to indicate that a failure has occurred and the
Cx-brick is down.
•
Reset switch
resets the Cx-brick internal processors and ASICs. This reset will cause
a memory loss. (See non-maskable interrupt [NMI] to perform a reset without
losing register data.)
•
NMI switch
resets the Cx-brick internal processors and ASICs and writes the
contents of the registers and memory to a
/var/adm/crash
file. (This switch is not
used by the memory-only Cx-brick.)
•
Three fans
provide N+1 redundant cooling for the brick.
