Potential Cause Solution for Troubleshooting
Status Red Fan speed has
deviated by 30%
from the target
speed or has failed.
Check the fault being reported by the faulty fan, by selecting
FAN-x-y FAN9HU (SH9HU shelf) or FAN-x-y FANXHU
(SHX9HU shelf), where x is the shelf number and y is the
fan number.
If the fault is VOLTANR:
1 Verify that the main supply feeding the associated
power supply units is operating within specifications.
2 Verify that the power supply modules have not failed,
and that the shelf is equipped according to engineering
guidelines for power consumption with respect to the
power supply modules used within the shelf.
3 If there are multiple modules within the same shelf
reporting this condition, replace the associated power
supply units.
4 If there are multiple fan modules within the same shelf
but only one is reporting this condition, replace that
module.
Or, if the FANANR condition is raised, replace the fan at the
earliest opportunity.
Yellow The fan speed has
deviated from the
target speed by over
15%, or the voltage
applied to the fan
exceeds
specifications.
Green All fans are operating
properly.
No action is required.
Table 12: LED Status of the FAN/9HUand FAN/X9HU
SH9HU and SHX9HU Slot Status LEDs
The SH9HU and SHX9HU slot status LEDs are located on the CEM/9HU front panel. The CEM/9HU has one
status LED indicator per slot. Slot LEDs indicate the operating status of the inserted modules and the
communication status to the management. Each SH9HU/SHX9HU shelf has 22 slots.
Each slot has its corresponding LED:
• “A” and “B” indicate the operating status of the half-sized modules SCU and NCU.
• “1” ... “20” indicate the communication status from the respective module to the SCU and NCU.
If the LED of the operating module is lit green, the module is operating properly and there is no failure. If the LED
is lit yellow, red, or off, the module is faulty or does not work.
Table 13 on p.84 provides troubleshooting guidelines for SH9HU and SHX9HU slot status LEDs.
Note
Before you start with troubleshooting, ensure that the NEis operating with the required NCU
software and module firmware. For details on updating NCU software and module firmware,
refer to “Updating the NE Software Release” on p.617 and “Performing Other Software Update
Actions” on p.628.
Note
Before you start with troubleshooting, be sure that the admin status on the affected module is set
to “Maintenance”.
