Checking for Power Supply Alarms
To check for power supply alarms:
- Displaying Current Power Supply Alarms
- Display Power Supply Error Messages in the System Log File
- Display Power Supply Error Messages in the Chassis Daemon Log File
Displaying Current Power Supply Alarms
Purpose
To determine the details of the current power supply alarms.
Action
To display power supply alarms, use the following command:
Sample Output
user@host> show chassis alarms 4 alarms currently active Alarm time Class Description 2002-04-08 15:25:12 PDT Major Power Supply A 2.5 volt output failed 2002-04-08 15:25:12 PDT Major Power Supply A 5 volt output failed 2002-04-08 15:25:12 PDT Major Power Supply A 3.3 volt output failed 2002-04-08 15:25:12 PDT Major Power Supply A fan failed
Meaning
The command output displays the alarm date, time, severity level, and description. Table 1 shows the power supply alarm descriptions that you see on the craft interface LCD and the alarms that you see at the CLI. For information about conditions that trigger power supply alarms, see Gather Component Alarm Information.

For information about what conditions trigger power supply alarms and their remedy for each router type, see Display the Current Router Alarms.
To display current power supply alarms and the alarm indicator states, use the following command:
Sample Output
user@host> show chassis craft-interfaceRed alarm: LED on, relay on
Yellow alarm: LED off, relay off
Host OK LED: On
Host fail LED: Off
FPCs 0 1 2 3
-------------------
Green * * * *
Red . . . .
LCD screen:
+--------------------+
|myrouter |
|4 Alarms active |
|R: Supply A 2v FAIL |
|R: Supply A 5v FAIL |
+--------------------+
The command output displays the alarm indicator status and the alarms that display on the craft interface LCD display.
(For M7i router) Check the red and yellow alarm LEDs on the FIC. Power supply failure or removal triggers an alarm that causes one or both of the LEDs to light.
Display Power Supply Error Messages in the System Log File
Purpose
To determine the details of the power supply error messages in the system log file.
Action
To display power supply error messages that are generated in the system log file, use the following command:
Sample Output
user@host> show log messages | match “power
supply” Apr 8 14:00:15 myrouter scb CM: ALARM SET: (Major) Power Supply A fan failed Apr 8 14:00:15 myrouter alarmd[584]: Alarm cleared: Pwr supply color=RED, class=CHASSIS, myrouter=Power Supply A fan failed Apr 8 14:00:18 myrouter scb CM: ALARM CLEAR: Power Supply A fan failed Apr 8 14:00:21 myrouter alarmd[584]: Alarm set: Pwr supply color=RED, class=CHASSIS, reason=Power Supply A fan failed Apr 8 14:00:23 myrouter scb CM: ALARM SET: (Major) Power Supply A fan failed Apr 8 14:05:16 myrouter alarmd[584]: Alarm set: Pwr supply color=RED, class=CHASSIS, reason=Power Supply A fan failed
Meaning
The messages system log file records the time the failure or event occurred, the severity level, a code, and a message description. Use the show log messages | match “power supply” command to view only power supply error messages. Use this information to diagnose a power supply problem and to let the Juniper Networks Technical Assistance Center (JTAC) know what error messages were generated and the router events prior to the problem. For more information about system log messages, see the Junos OS System Log Messages Reference.
Display Power Supply Error Messages in the Chassis Daemon Log File
Purpose
To determine the details of the power supply error messages in the chassis daemon log file.
Action
To display power supply error messages in the chassisd log file, use the following command:
Sample Output
user@host> show log chassisd | match pem Jul 15 11:18:59 CMB cmd to PEM#0 [0xf8], Amber LED Off [0x18] Jul 15 11:18:59 PEM#0 - Amber LED Off Jul 15 11:18:59 CMB cmd to PEM#0 [0xf8], Green LED Off [0x1a] Jul 15 11:18:59 PEM#0 - Green LED Off Jul 15 11:18:59 CMB cmd to PEM#0 [0xf8], Blue LED Off [0x16] Jul 15 11:18:59 PEM#0 - Blue LED Off Jul 15 11:18:59 CMB cmd to PEM#1 [0xf9], Amber LED Off [0x18] Jul 15 11:18:59 PEM#1 - Amber LED Off Jul 15 11:18:59 CMB cmd to PEM#1 [0xf9], Green LED Off [0x1a] Jul 15 11:18:59 PEM#1 - Green LED Off Jul 15 11:18:59 CMB cmd to PEM#1 [0xf9], Blue LED Off [0x16] Jul 15 11:18:59 PEM#1 - Blue LED Off Jul 15 11:19:02 PEM#0 added Jul 15 11:19:02 reading PEM 0 initial state Jul 15 11:19:02 PEM#1 added Jul 15 11:19:02 reading PEM 1 initial state Jul 15 11:19:18 CHASSISD_PEM_INPUT_BAD: PEM 1 - INPUT FAIL, status bits: 0xf2, check breaker Jul 15 11:19:18 CHASSISD_SNMP_TRAP: SNMP trap: FRU failure: jnxFruContentsIndex 2, jnxFruL1Index 2, jnxFruL2Index 0, jnxFruL3Index 0, jnxFruName PEM 1, jnxFruType 7, jnxFruSlot 2, jnxFruOfflineReason 2, jnxFruLastPowerOff 0, jnxFruLastPowerOn 26221491, jnxFruPowerUpTime 1484 Jul 15 11:19:23 CHASSISD_PEM_INPUT_BAD: PEM 1 - INPUT FAIL, status bits: 0xf2, check breaker Jul 15 11:19:28 CHASSISD_PEM_INPUT_BAD: PEM 1 - INPUT FAIL, status bits: 0xf2, check breaker Jul 15 11:19:33 CHASSISD_PEM_INPUT_BAD: PEM 1 - INPUT FAIL, status bits: 0xf2, check breaker Jul 15 11:19:38 CHASSISD_PEM_INPUT_BAD: PEM 1 - INPUT FAIL, status bits: 0xf2, check breaker
Meaning
The chassisd database provides the date, time, and a component status message. The chassisd database is dynamic. It is initialized at router startup and is updated when components are added or removed.
