Warning When installing the unit, the ground connection must always be made first and disconnected last.

Step 6 Attach the ground wire to the ground terminals using the 8-mm nut driver.

Step 7 Check the power supply’s wiring and wiring color code to verify that it matches the wiring and color code at the DC source.

Warning Incorrectly wiring the terminal block could create a dangerous shock hazard and could damage the power supply, power source, and the chassis components.

Step 8 Replace the terminal block cover. (Refer to Figure 3-19.)

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

Step 9 After the DC power cable leads are connected to the DC-input power supply, reconnect the power cable at the power source.

If you plan to add a second power supply, repeat Step 1 through Step 9.

Note Do not turn on any power supplies until you are ready to power up the system. The interlock switch that locks the power supply in the slot also turns on the system power.

This completes the procedures required to install the Cisco 7513, Cisco 7513-MX, and Cisco 7576.
