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
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
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
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
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
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
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.
