LED Label	LED	Color	Description
FAN OK	Bi-color LED indicates	Green	LED illuminates green when all fans are operational.
	fan status
		Red	The LED illuminates red when a fan failure is detected.
OUTPUT FAIL	Power supply activity	Red	LED is red and turned off to signal that the DC output
			voltages are within the normal operating range; output
			voltage between the minimum and maximum limits will
			not create an output fail alarm, and output voltages below
			the minimum or above the maximum will create an output

Cisco ASR Router 1004 DC Power Supply

This section provides information about the DC power supplies on the rear of the Cisco ASR 1004 Router. For the maximum branch circuit for the DC power supply module, see Table 2-8.

The DC power supply operates within specification from –48 VDC to –60 VDC continuously. The Cisco ASR 1004 Router has two of the same type power supplies in power supply slot 0 and power supply slot 1. The power supply slot numbers are on the left side of the chassis and the power supplies are located on the floor of the chassis.

The DC power supply input connector is a terminal block style that will allow crimp type lugs accepting up to AWG #8 wire. The terminal block is compliant to all safety agencies and electrical requirements of the supply. The terminal block accepts two-hole lugs (#10 stud) for all connections with center to center spacing of 0.625 inches. A plastic cover goes over the terminal block to prevent accidental contact. The connection order shall be negative (–), positive (+), and GND terminals.

The unit requires a power switch circuit breaker to serve as the main disconnect for the DC input to the power supply (Table 2-8see for current rating requirements.) The power supply unit is secured into the system chassis with four captive screws mounted on the faceplate.
