Note When securing the ground, +48V, and –48V DC-input leads to the power supply faceplate, leave
a small service loop in the ground lead to ensure that the ground lead is the last lead to disconnect
from the power supply if a great deal of strain is placed on all three leads (refer to Figure3-22).
Step7 Connect the ground, +48V, and –48V leads to the power source.
Note Each DC-input power supply operating at –48 VDC in North America requires a minimum of 13A
service. Each DC-input power supply operating at –60 VDC in the European Community requires a
minimum of 8A service.
This product relies on the building’s installation for short-circuit (overcurrent) protectio n. E nsur e that a
listed and certified fuse or circuit breaker, 20A minimum 60 VDC, is used on all current-carrying
conductors.
This completes the procedure for connecting DC-input power. Proceed to the following section,
“Starting the Cisco 7204,” to start the router.
Starting the Cisco 7204
After installing your Cisco7204 and connecting cables, start the router as follows:
Step1 Check for the following:
•Each port adapter is inserted in its slot and its respective port adapter lever is in the locked position.
•The network processing engine and the I/O controller are inserted in their slots and thei r captive
installation screws are tightened.
•All network interface cables are connected to the port adapters.
•A Flash memory card is installed in its PCMCIA slot.
•Each power cable is connected and secured with the cable-retention clip.
•The console terminal is turned on.
Step2 At the rear of the router, place the power switch on the power supply in the ON (|) position. Repeat this
if a second power supply is installed. The green OK LED on the power supply turns on.
Step3 Listen for the fans; you should immediately hear them operating.
Step4 During the boot process, observe the system LEDs. The LEDs on most o f the port adapters go on and off
in irregular sequence. Some may go on, go out, and go on again for a sh ort time . O n th e I /O c on trol ler,
the IO power OK LED comes on immediately.
