Powering on a Switch for the First Time
Turn on the circuit breakers on the power distribution frame and power distribution box in turn, and then turn on the power switches on the power modules of the switch. Observe indicators of modules on the switch.
The colors and meaning of indicators on the S12704, S12708, S12710, S12712, S12700E-4, S12700E-8, and S12700E-12 switches are the same. Indicators on an S12708 switch are used as an example here.
Figure 11-1 shows the indicators at the front of an S12708 switch.
Figure 11-2 shows the indicators at the rear of an S12708 switch.
Table 11-1 lists the indicator states after the switch is powered on.

1 |
800 W AC power module |
RUN |
Green |
Steady on: The power input is normal. |
ALM |
Green |
Steady on: The output power of the power module is in the normal range. Off: The power module provides no output power. |
||
FAULT |
Red |
Steady on: The power module has a fault that cannot be rectified. |
||
|
INPUT |
Green |
Steady on: The input power of the power module is in the normal range. Blinking: The power module is in an input undervoltage or input overvoltage condition. Off: The power module receives no input power. |
|
OUTPUT |
Green |
Steady on: The output power of the power module is in the normal range. Off: The power module provides no output power. |
||
ALARM |
Red |
Steady on: The power voltage is experiencing overtemperature, external short circuit, output overvoltage, output overcurrent, or a fan failure. Blinking: Communication between the power module and CMU has been interrupted. Off: The power module is working normally. |
||
2 |
CMU |
RUN/ALM |
Green |
Slow blinking: The system software of the card is running normally. Fast blinking: The system software of the card is unregistered. |
Red |
Steady on: The card has failed, and the fault requires manual intervention. Slow blinking: The switch is reporting an alarm. For example, a CMU, fan module, or power module on the switch fails. Fast blinking: The input power is insufficient. |
|||
ACT |
Green |
Steady on: The card is the active CMU. Off: The card is the standby CMU. |
||
3 |
SFU |
RUN/ALM |
Green |
Steady on: The card has been powered on, but the software is not running. Slow blinking: The card software is running properly. Fast blinking: The card software is starting. |
Red |
Steady on: The card has failed, and the fault requires manual intervention. |
|||
Yellow |
Steady on: The card is in power-off state. (For example, the card has been forcibly powered off using the power off command or is about to start.) |
|||
4 |
LPU |
RUN/ALM |
Green |
Steady on: The card has been powered on but the system software is not running. Slow blinking: The system software of the card is running normally. Fast blinking: The system software of the card is starting. |
Red |
Steady on: The card has failed, and the fault requires manual intervention. |
|||
Yellow |
Steady on: The card is in power-off state. (For example, the card has been forcibly powered off using the power off command or is about to start.) |
|||
5 |
MPU |
RUN/ALM |
Green |
Steady on: The card has been powered on but the system software is not running. Slow blinking: The system software of the card is running normally. Fast blinking: The system software of the card is starting. |
Red |
Steady on: The card has failed, and the fault requires manual intervention. |
|||
Yellow |
Steady on: The card is powered off. |
|||
ACT |
Green |
Steady on: The card is the active MPU of the switch. Off: The card is the standby MPU of the switch. |
||
6 |
Fan module |
RUN/ALM |
Green |
Slow blinking: The fan module is working and communicating with the system normally. Fast blinking: The fan module is working normally but is not communicating with the system. |
Red |
Slow blinking: An alarm was generated. You must determine whether to replace the fan module, depending on the actual situation. Steady on: The fan module has a hardware failure and needs to be replaced. |
