time when bringing the module back online. You can recover the configuration by downloading it from
the server to the nonvolatile memory of the supervisor engine. For more information, refer to the
"Working with Configuration Files" chapter in the Catalyst 6500 Series Software Configuration Guide.

Statement 1
Catalyst 6509-NEB Switch and Cisco OSR-7609 Router Upgrade Note
4
If your switch or router is using an AC-input power supply, you are required to install the
WS-CAC-3000W power supply. The 3000 W AC-input provides a power output to power the fan
tray.
If your switch or router is using a DC-input power supply, you are required to install the
WS-CDC-2500W or PWR-4000-DC power supply. You must provide a separate, direct connection
to power the fan tray. Each input of the fan tray is rated 10 A @ -40 to -60 VDC.
Observe the following cautions:
It is important that you follow the steps in this document in the order they are presented.
Always use an ESD wrist strap when handling modules or coming into contact with internal
components.
Use both hands to install and remove power supplies. Each Catalyst 6500 series AC-input
power supply weighs between 22 pounds (9.9 kg) and 28 pounds (12.6 kg).
Do not exert too much pressure on the ejector levers. They will bend and be damaged.
In a system with dual power supplies, connect each power supply to a separate input source.
In case of a power source failure, the second source will most likely still be available.
