How to Debug/Troubleshoot Power Issues on a PA-7050
Resolution
Details
There are CLI commands on the PA-7050 designed to indicate power issues on the platform. Shown below are the CLI commands and details to check and to detect any power issues:
> show chassis power

1 PA-7000-20G-NPC Up 350
2 empty
3 empty
4 PA-7050-SMC Up 300

In the sample output above, there are 2 NPC (Network Processing Cards) in the chassis. They are Slot 1 and 7. Slot 4 is the Switch Management Card (SMC) or the Management Plane (MP) for the chassis. Slot 8 is the Log Processing Card ( LPC).
The Power Column indicates the value of power consumed and confirms the power inputs to the slots. PS1, PS2, PS3, PS4 are the Power Supplies and the status indicates they are OK. Each power supply inputs 2500 watts to the chassis summing up to 10,000 watts to the platform. Shown below, notice that the split up is given for the amount of power used by the chassis (1300 watts):
The show chassis inventory command displays valuable information such as Serial Number of the Slots and Power Supplies.
For example:
> show chassis inventory

The show chassis status command provides another validation that a particular card is being powered on and the status is up:
> show chassis status
Chassis autocommit ready : True
Inserted slots : 1 4 7 8
Powered slots : 1 4 8
Points to note:
- Inserted Slots - Indicates that the cards are Inserted properly and there is no disconnects between the Card inserted and the slot.
- Powered Slots - Indicates the Cards which are being powered rightly.
The show system state command with a match for 'card_status' shows information about the slot cards:
> show system state | match card_status
chassis.s1.card_status: { 'detail': Card is powered on and system software is running, 'status': Up, }
Note: s1 indicates slot 1
The show system state command with a match for 'chassis.summary' will share the state of the chassis. This also shows if the auto commit is completed or not, which indicates the device is booted properly and good to pass traffic as configured.
> show system state | match chassis.summary
chassis.summary: { 'autocommit_completed': True, 'autocommit_ready': True, 'config_done': 0x89, 'config_ready': 0x89, 'inserted': 0xc9, 'lpc_slots': 0x80, 'powered': 0x89, 'pp_enabled': 0x1, 'ppc_slots': 0x41, 'software_ready': True, 'sw_running': 0x89, 'traffic_enabled': 0x89, }
The show system state with a match for 'chassis.leds' allows the user to view the led lights status pertaining to the chassis. The output below indicates a healthy functional unit:
> show system state | match chassis.leds
chassis.leds: { 'alarm': Off, 'fans': Green, 'ha': Off, 'log': Off, 'ps0': Green, 'status': Green, 'temp': Green, }
From the management plane, there can be more references obtained pertaining to the power, fan and related logs. Run the following command to display this information:
> less mp-log chasd.log
