Powering on a Switch for the First Time

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.

NOTE:

The colors and meaning of indicators on the S9300&S9300E&S9300X switches are the same. Indicators on an S9306 switch are used as an example here.

Figure 11-1 shows the indicators at the front of an S9306 switch.

Figure 11-2 shows the indicators at the rear of an S9306 switch.

Table 11-1 lists the indicator states after the switch is powered on.

Description

1

  • 1600 W DC power module (S9303&S9306&S9312)

  • 2400 W DC power module (S9300&S9300E&S9300X)

INPUT

Green

Steady on: The input power is normal.

Off: No input power is available.

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 protection circuit has failed.

Off: The protection circuit is working properly.

  • 800 W AC power module (S9300&S9300E&S9300X)

  • 2200 W AC power module (W2PSA2230) (S9300&S9300E&S9300X)

  • 2200 W DC power module (S9300&S9300E&S9300X)

RUN

Green

Steady on: The power input is normal.

ALM

Yellow

Steady on: A power output shutdown alarm, overtemperature alarm, output overcurrent alarm, input overvoltage alarm, or input undervoltage alarm has been generated.

Blinking: Communication with the monitoring device (MCU or CMU) has been interrupted.

FAULT

Red

Steady on: The power module has a fault that cannot be rectified.

  • 3000 W AC power module (S9300&S9300E&S9300X)

  • 3000 W high-voltage DC power module (S9300&S9300E&S9300X)

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

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.

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.)

Red

Steady on: The card has failed, and the fault requires manual intervention.

4

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.

5

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.
