Edition One
XC1000 Service
2. Check menu 13.11, Card Management, and verify that all cards are
active.
3. Open the front doors of the XC1000.
4. Look at the LEDs on the front edges of the logic cards. Replace any
card with an illuminated
L2
LED. An
L2
LED indicates a problem
with the logic card. If all of the logic cards appear to be working,
then one of the disk drives is probably faulty.
5. Open the rear doors of the cabinet. Ensure that the three LEDs on
each disk-drive front panel, as shown in Figure 6-12, are lit as follows:
During normal operation, the green
RUN
LED is on, the red
INOP
LED
is off, and the yellow
SEL
LED flashes on during read and write
operations. If the
RUN
LED is off or the
INOP
LED is on, the drive is
faulty. Troubleshoot the drive, as described in section 6.2.4.5.
6. After replacing a suspected logic card or drive, clear all alarms in
menu 13.8, Review Current Alarm Status, and verify that the monitor
card SA and HW LEDs go off.
