Figure 2-19 Power Supply for Cisco MDS 9506 Director
To provide power to an AC power supply in a Cisco MDS 9509 Director or a Cisco MDS 9506 Director,
follow these steps:
Step 1 Plug the power cable into the switch as follows:
• For the Cisco MDS 9509 Director, plug the power cable into the power supply and tighten the screw
on the power cable retainer to ensure that the cable cannot be pulled out.
Note The 4000-W AC power supply for the Cisco MDS 9509 Director has a permanent power cable
attached.
• For the Cisco MDS 9506 Director, plug the power cable into the AC PEM on the front of the chassis.
Step 2 Connect the other end of the power cable to a power source.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional
jumper power cord to connect the Cisco MDS 9500 Series director to your outlet receptacle. See
the “Jumper Power Cord” section on page E-11.
