Chapter 2 Installing the Cisco MDS 9500 Series
Removing and Installing a Power Supply or PEM
Installing an AC PEM
To install an AC PEM in a Cisco MDS 9506 chassis, follow these steps:
Step 1
Ensure that the system (earth) ground connection has been made. See the
“System Grounding” section
on page 2-17
.
Step 2
If a filler panel is installed, remove it from the PEM bay by loosening the captive screws and pulling it
from the chassis.
Step 3
Slide the PEM into the PEM bay, ensuring that the PEM is fully seated in the bay.
Step 4
Tighten the PEM captive screws to 8 in-lb.
Step 5
Provide power to the PEM as described in the
“Providing Power to an AC Power Supply for the Cisco
MDS 9509 and Cisco MDS 9506 Directors” section on page 2-30
.
Caution
In a system with dual power supplies, connect each power supply to a separate power source.
In case of a power source failure, the second source will most likely still be available.
Step 6
Verify PEM and power supply operation by checking the power supply LED states in the back of the
chassis:
•
INPUT OK LED is green.
•
FAN OK LED is green.
•
OUTPUT FAIL LED is off.
Installing a DC PEM
To install a DC PEM in a Cisco MDS 9506 chassis, follow these steps:
Step 1
Ensure that the system (earth) ground connection has been made. See the
“System Grounding” section
on page 2-17
.
Step 2
If a filler panel is installed, remove it from the PEM bay by loosening the captive screws and pulling it
from the chassis.
Step 3
Attach the DC power cables to the PEM as described in
“Providing Power to a DC Power Supply in the
Cisco MDS 9506 Director” section on page 2-34
.
Step 4
Slide the PEM into the PEM bay, ensuring that the PEM is fully seated in the bay.
Step 5
Tighten the PEM captive screws to 8 in-lb.
Caution
In a system with dual power supplies, connect each power supply to a separate power source.
In case of a power source failure, the second source will most likely still be available.
Step 6
Verify PEM and power supply operation by checking the power supply LED states in the back of the
chassis:
•
INPUT OK LED is green.
•
FAN OK LED is green.
