Displaying System PoE Status
To display the PoE status for the switch, use the following command:
show inline-power
The command provides status for the following areas:
● Configured inline power status—The status of the inline power for the switch: enabled or disabled.
● System power surplus—The surplus amount of power on the system, in watts, available for
budgeting.
● Redundant power surplus—The amount of power on the system, in watts, available for budgeting if
one power supply is lost.
● System power usage threshold—The configured power usage threshold for each slot, shown as a
percentage of budgeted power. Once this threshold has been passed on any slot, the system sends an
SNMP event and logs a message.
● Disconnect precedence—The method of denying power to PDs if the budgeted power on any slot is
exceeded.
● Legacy mode—The status of the legacy mode, which allows detection of non-standard PDs.
The output indicates the following inline power status information for each slot:
● Inline power status—The status of inline power. The status conditions are:
■ Enabled
■ Disabled
● Firmware status—The operational status of the slot. The status conditions are:
■ Operational
■ Not operational
■ Disabled
■ Subsystem failure
■ Card not present
■ Slot disabled
● Budgeted power—The amount of inline power, in watts, that is reserved and available to the slot.
● Measured power—The amount of power, in watts, that is currently being used by the slot.
Following is sample output from this command:
Inline Power System Information
Configured : Enabled
System Power Surplus : 1500 Watts available for budgeting
Redundant Power Surplus : 465 Watts available for budgeting to maintain N+1
Power Usage Threshold : 70 percent (per slot)
Disconnect Precedence : lowest-priority
Legacy Mode : Disabled
Budgeted Measured
Slot Inline-Power Firmware Status Power (Watts) Power (Watts)
3 Enabled Operational 50 W 9 W
4 Enabled Card Not Present ( 50 W) n/a
7 Enabled Operational 50 W 0 W
Note: A budget value in parentheses is not allocated from the system power
budget because the card is not present, or the slot is disabled.
