Cisco CATALYST 6509E 9 SLOT 15U CHASSIS NO POWER SUPPLY NO FAN TRAY 规格指南

This section covers the power supply removal and installation procedures for the 1300 W and the 
2500 W DC-input power supplies and is divided into the following topics:

Use a flat-blade or number 2 Phillips-head screwdriver to perform these procedures. You might also need 
cutters to cut any cable ties that are installed on the power supply.

Before performing any of the following procedures, ensure that power is removed from the DC 
circuits. To ensure that all power is removed, locate the circuit breakers or fuses on the DC power 
lines that service the DC circuits. Turn OFF the DC power line circuit breakers and remove the DC 
power line fuses. Statement 322

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution 
when servicing. Statement 1034

When installing or replacing the unit, the ground connection must always be made first and 
disconnected last. Statement 1046

To remove a DC-input power supply, follow these steps:

Verify that power is off to the DC circuit on the power supply that you are removing. As an added 
precaution, place the appropriate safety flag and lockout devices at the source power circuit breaker, or 
place a piece of adhesive tape over the circuit breaker handle to prevent accidental power restoration 
while you are working on the circuit.

Turn the power switch to the Off (0) position on the power supply that you are removing. (See 

 for the 1300 W DC power supply or 

 for the 2500 W DC power supply.) Turning 

the power switch off also disengages a pawl that unlocks the power supply from the chassis.

Remove the two screws securing the terminal block cover, and slide the cover off the terminal block. 
(See 

 for the 1300 W DC power supply or 

 for the 2500 W DC power supply.)
