Power problems
•
If the yellow Fault LED on the power module
is on:
–
Make sure the power switch on the power
module is set to | (On).
–
Make sure the power and ground wires are
properly connected to the terminals on the
PEM. Follow the wiring instructions
carefully to ensure that you insert the wires
into the correct openings in the terminal
block. See the
“Wiring a DC PEM” section
on page 12
for details.
•
If the Miswire LED on the DC PEM is on, the
–48V and return (RTN) wires are reversed. Power
off the PEM, turn off the branch circuit that feeds
power to the Cisco 10005, and reconnect the
wires correctly. (See the
“Wiring a DC PEM”
section on page 12
for details.)
