Appendix A Implementation Checklist
Cisco Fixed Switches:
1.
Verify power is administratively enabled on all appropriate ports.
a.
Use the command
b.
Admin column values Auto or Static allow power, Never disables power to that port.
c.
Max max-wattage option with Auto or Static variables will allow power or pre-configure
power to a port, but will disable power to an Avaya phone if set lower than the maximum
value of the phones power class..
i.
d.
If applicable, use the command in step 3 instead of the Max max-wattage command.
2. Check possibility of reclaiming logical power
a.
Reclaimed logical power is available beginning with IOS 12.2(25)SEC for a Catalyst 3750
3.
Verify IOS is safe for PDs
a.
Use the command
b.
Never use IOS earlier than 12.2(20)SE1 because power could still flow through a port even
after the valid PD was removed. This might damage a non-PD device.
Cisco Chassis Switches:
4.
Verify power supply(s) status and available power.
a.
Use the command
5.
Verify power statistics at the line card level.
a.
Use the command
6.
Verify module status, model and, if applicable, daughter card model
a.
Use the command
7.
Verify module status, model and, if applicable, daughter card model
a.
Use the command
power"
b.
Check admin column. Auto allows power, Never denies power on a port
c.
Check oper column. On means power is flowing. Off indicates no power is flowing. A
problem exists if you see faulty or deny.
d.
Carefully check the column titled "Power from PS mWatts". This is logical power allocated
for each port. The sum of this column reveals how much power is logically reserved from
the power supply(s) at that time.
