Appendix A
Implementation Checklist
Cisco Fixed Switches:
1.
Verify power is administratively enabled on all appropriate ports.
a.
Use the command
“show power online”
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.
If you see
“power-deny”
instead of
“
on
”
,
in the oper column, either the
PD requested too much power or the max value was lower than the class
maximum value.
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
“power inline consumption default”
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
“show system”
5.
Verify power statistics at the line card level.
a.
Use the command
“show environment power”
6.
Verify module status, model and, if applicable, daughter card model
a.
Use the command
“show module <module number>”
7.
Verify module status, model and, if applicable, daughter card model
a.
Use the command
“show port inline power”
or
“show inline
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.
