Troubleshooting
When you start up the system by turning the power supply switch to the ON (|) position, the following
should occur:
1. Fans—The fans start operating. The FAN OK LED on the fan assembly module illuminates (green).
DC PEM
2.

•
TCC+ card—The POWER LED illuminates (green), the STATUS LED illuminates yellow then turns
4.
green (active) or blinking green (backup). PRESENT LED comes illuminates (green).
DTCC card—The POWER LED illuminates (green), the STATUS LED comes on yellow then turns
5.
green (active) or blinking green (backup). PRESENT LED illuminates (green).
PREs—The FAIL LEDs on the PRE modules briefly illuminate during the power-on sequence and
6.
then go off and the STATUS LEDs illuminate green.
Note
7. Line cards/adapter cards and uplink cards—ENABLED LEDs turn green and then goes off.
Note
The initial system banner appears on the console screen.

UBR10-PWR-DC= module—If you are using this module, the POWER LED on the DC PEM
illuminates (green) to indicate that the PEM is connected to an active DC power source and is
supplying power to the chassis.
UBR10-PWR-DC-PLUS= module—If you are using this module, the V1 POWER and V2
POWER LEDs on each DC PEM module illuminate (green) to indicate that the DC PEM module
is connected to active DC power sources. These LEDs only indicate that an input voltage is
present on the PEMs and not that the PEM is powered on. These LEDs serve as a warning that
a voltage is currently applied to the AC PEM module. In addition, the POWER LED on the
modules illuminates (green) to indicate that it is supplying the required power to the
Cisco uBR10012 chassis.
UBR10-PWR-AC= module—If you are using this module, the POWER LED on the AC PEM
illuminates (green) to indicate that the PEM is connected to an active AC power source and is
supplying power to the chassis.
UBR10-PWR-AC-PLUS= module—If you are using this module, the V1 POWER and V2
POWER LEDs on each AC PEM module illuminates (green) to indicate that the AC PEM
module is connected to active AC power sources. These LEDs only indicate that an input
voltage is present on the PEMs and not that the PEM is powered on. These LEDs serve as a
warning that a voltage is currently applied to the AC PEM module. In addition, the POWER
LED on the modules illuminates (green) to indicate that it is supplying the required power to
the Cisco uBR10012 chassis.
The Slot 0 and Slot 1 LEDs on the PRE illuminate only when the PCMCIA card slots are being
accessed by the system. These LEDs remain off during normal operation of the router and do not
indicate startup problems.
Each line card has an ENABLED LED that comes on initially at power-on and then goes off. The
LED then comes on and remains on when the corresponding port is enabled and configured for
operations.
