Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY Specification Guide

Attach the appropriate lugs to the DC-input wires. The maximum width of a lug is 0.300 inch (7.6 mm). 

The wire should be sized according to local and national installation requirements and electrical 
codes. Use only copper wire. For North American installations of 2500 WDC-input power 
supplies, use fine-stranded copper conductors rated for 90°C.

Connect the DC-input wires to the terminal block (see 

 for the 1300 W DC power supply or 

 for the 2500 W DC power supply) in this order:

Ground

Negative (–)

Positive (+)

The terminals on the 1300 W DC power supply DC power cable terminal block are labeled (from 
top to bottom) +, –, ground. The terminals on the 2500 W DC power supply DC power cable 
terminal block are labeled (from top to bottom) –, +, ground.

After ensuring that all wire connections are secure, reinstall the terminal block cover.

To prevent a short circuit or shock hazard after wiring the DC-input power supply, you must reinstall the 
terminal block cover.

In a system with dual power supplies, connect each power supply to a separate power source. In case of 
a power source failure to one supply, the second power source should still be available.

Remove any safety flag and lockout devices or any tape from the circuit breaker switch handle, and 
restore power by moving the circuit breaker switch handle to the On (|) position.

Turn the power switch to the On (|) position on the power supply. Turning on the power switch also 
engages a pawl that locks the power supply in the chassis.

Verify the power supply operation by ensuring that the power supply front panel LEDs are in these states:

INPUT OK LED is green

FAN OK LED is green

OUTPUT FAIL LED is not lit

If the LEDs indicate a power problem, see the
