Caution To ensure the proper flow of cooling air across the internal components, make sure a port adapter blank
panel is installed in the unoccupied port adapter slot.
This completes the port adapter installation procedure. For information about configuring a port adapter,
see the Cisco 7201 Port Adapter Documentation Roadmap which provides a linked list of all port adapter
documentation for the Cisco 7201 router.
Removing and Installing an AC Power Supply
For AC power supply specifications and product numbers, see Appendix A, “Specifications.”
This section provides information about removing and replacing an AC power supply. Because of the
power supply redundancy, there is no need to power off the Cisco 7201 router before removing one of
the AC power supplies.
The Cisco 7201 has two of the same type of power supplies in power supply slot 1 and power supply
slot 2. (See Figure 4-5.)
