To prepare the cable wires for the 1100 W DC power supply unit, follow these steps:
1 Strip 0.4 inch (10 mm) of insulation from one end of each cable wire.
2 Insert the end of the stripped ground wire (green or green and yellow) all the way into the barrel of
the ring terminal and crimp the terminal securely to the wire.
Figure 156: Attaching a Ring Terminal to a Ground Cable
No ring terminal is required to connect the cable wires (non-ground wires) to the 1100 W DC power
supply.
Installing an 1100 W DC Power Supply
Before installing a Summit 1100 W DC power supply:
•
Verify that the switch rack or chassis has been grounded.
•
Verify that the airflow direction for the power supply is the same as the airflow direction of the
installed fan modules in the switch.
To install the power supply, follow these steps:
1 Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an
appropriate ground point on the rack.
2 If necessary, remove a blank panel from the rear of the switch.
3 Verify that the power supply is right side up.
The power supply should be oriented as shown in
4 Verify that the direction of ventilation airflow is the same for both the power supply and the switch.
In a switch with front-to-back airflow, the fan modules are labeled Air Out.
In a switch with back-to-front airflow, the fan modules are labeled Air In.
