Chapter 3 Installing the Cisco 7204
Connecting Power
Examine the sequence of colored wires to determine the type of RJ-45 cable as follows:
•
Straight-through—The colored wires are in the same sequence at both ends of the cable.
•
Crossover—The first (far left) colored wire at one end of the cable is the third colored wire at the
other end of the cable, and the second colored wire at one end of the cable is the sixth colored wire
at the other end of the cable.
Connecting Power
Warning
Read the installation instructions before you connect the system to its power source.
This section provides the procedures for connecting AC-input and DC-input power to your Cisco 7204.
Note
Detailed instructions for handling and replacing the Cisco 7204 power supplies are contained in the
configuration notes 280-Watt AC-Input Power Supply Replacement Instructions and 280-Watt DC-Input
Power Supply Replacement Instructions. These documents are available on Cisco.com.
Warning
Only trained and qualified personnel should be allowed to install or replace this equipment.
Connecting AC-Input Power
Connect a 280W AC-input power supply as follows:
Step 1
At the rear of the router, check that the power switch on the power supply is in the OFF (O) position.
Step 2
Slide the cable-retention clip up, away from the AC receptacle, and plug in the power cable.
Step 3
Secure the cable in the power supply AC receptacle by sliding the cable-retention clip up until it fits
around the connector. The cable-retention clip provides strain relief for the AC power cable (refer to
Figure 3-20
).
Note
For additional AC power cable strain relief, secure the cable to the power supply handle by
inserting a nylon cable tie through the hole in the handle and around the cable.
