•Keep the IES power switches in the OFF position until you come to procedure for turning on the power.
•Keep the power supply switch in the OFF position until you come to procedure for turning on the power.
Use only power wires of the required diameter for connecting the IES to a power supply (refer to Chapter 5 on page 75 for the required wire gauge).
2.8.1 Power Modules
The main chassis uses two power supply modules. These modules are hot- swappable and supply power to the line cards.
The power connections are on the front of each power module. The power modules are in the upper left and upper right corners of the front panel of the main chassis.
2.8.1.1 Procedure to Connect the Power
When installing the IES power wires, push the wires firmly into the terminals as deep as possible and make sure that no exposed (bare) wires can be seen or touched.
Use four wires to connect to each power module, two wires for the positive terminals and two wires for the negative terminals.
1Use a screwdriver to loosen the power module screws.
2Slide the power module out partially to expose the power terminal screws.
3Connect power wires to the negative power terminals on the front of the power module, and tighten the terminal screw.
4Connect the other ends of the power wires to the
5Connect power wires to the positive power terminals on the front of the IES power module, and tighten the terminal screw.
6Connect the other ends of the power wires to the ground terminal on the power supply.
7Push the power module back in and tighten the screws.
8Repeat the previous steps for the second power supply module.
