Post-Startup Checklist

Post-Startup Checklist

After powering on the device, you need to check whether the device is running properly based on the post-startup checklist.

NOTE:

This section provides post-startup checklist for an AC-powered device. For post-startup checklist for a DC power device, use the post-startup checklist for an AC-powered device as a reference.

Post-Startup Check Flowchart

The following figure shows the post-startup check flowchart.

Post-Startup Checklist for the EPW50-48A

Before checking the device, switch all circuit breakers on the EPW50-48A to the OFF position.

The following figure shows the indicators on the EPW50-48A.

Figure 11-34 Indicators on the EPW50-48A

1. Operation indicator

2. Protection indicator

3. Fault indicator

The following table provides the checklist for the EPW50-48A.

Item

Indicator Color

Status Description

Cause of the Abnormality

Operation indicator

Green

If the indicator is steady green, the EPW50-48A is running properly. If the indicator is off, an exception occurs.

No main AC power is input, the AC input voltage is higher or lower than the normal range, or the EPW50-48A has no output.

Protection indicator

Yellow

If the indicator is off, the EPW50-48A is running properly. If the indicator is on, an exception occurs.

A temperature alarm is generated (if the temperature exceeds 65°C, the EPW50-48A will be powered off), or the EPW50-48A is in the dormant state (the indicator is on and no alarm is generated).

Fault indicator

Red

If the indicator is off, the EPW50-48A is running properly. If the indicator is on, an exception occurs.

The EPW50-48A is powered off due to over-voltage or over-temperature, or fans are faulty, or the EPW50-48A has no output due to its internal faults

DC output voltage

-

The normal voltage ranges from –43.2 V DC to –57 V DC

Post-Startup Checklist for the Device

The following table provides checklist for the device.

Component

Indicator

Color

Status Description

Power entry module (PEM)

RUN

Green

If the indicator is steady green, the PEM has normal output.

ALM

Red

Fault indicator. If the indicator is steady red,

  • Lighting protection circuit of the PEM is faulty.
  • The PEM does not have input power.

Fan module (FAN)

STATUS

Green

If the indicator blinks green once every two seconds (0.5 Hz), the FAN is working properly.

Red

If the indicator is steady red, the FAN is faulty, or the PEM is faulty.

MPU

RUN

Green

From the MPU being powered on until it is registered, the indicator status changes in the sequence of off–blinks once every 500 ms (2 Hz)–off–steady on–blinks once every two seconds (0.5 Hz).

After the MPU is registered, the MPU is working properly if the indicator blinks at 0.5 Hz.

NOTE:

Possible causes for the indicator being off are:

  • The BootROM is damaged.
  • The MPU cannot be powered on.

Possible causes for the indicator blinking quickly are:

  • The CF card is faulty.
  • The other control chips on the MPU are faulty, causing the MPU not to be able to initialize.

ALM

Red

If the indicator is steady off, the MPU is in the normal state. If the indicator is steady red, an alarm is generated.

SFU

RUN

Green

From the SFU being powered on until it is registered, the indicator status changes in the sequence of off–blinks once every 500 ms (2 Hz)–off–steady on–blinks once every two seconds (0.5 Hz).

After the SFU is registered, the SFU is working properly if the indicator blinks at 0.5 Hz.

NOTE:

Possible causes for the indicator being off are:

  • The BootROM is damaged.
  • The SFU cannot be powered on.

Possible causes for the indicator blinking quickly are:

  • The flash memory is faulty.
  • The network port is faulty.

ACT

Green

If the indicator is steady green, the SFU is working properly; if the indicator is off, the SFU is faulty.

LPU

RUN

Green

From the LPU being powered on until it is registered, the indicator status changes in the sequence of off–blinks once every 500 ms (2 Hz)–off–steady on–blinks once every two seconds (0.5 Hz).

After the LPU is registered, the LPU is working properly if the indicator blinks at 0.5 Hz.

NOTE:

Possible causes for the indicator being off are:

  • The BootROM is damaged.
  • The LPU cannot be powered on.

Possible causes for the indicator blinking quickly are:

  • The flash memory is faulty.
  • The network port is faulty.

Link/ACT

Green

  • If this indicator is off, the link is Down.
  • If this indicator is steady on, the link is Up.
  • If this indicator is blinking, data is being transmitted.
