Upgrading the DC Power Supplies

Upgrading the DC Power Supplies

NOTE: You must upgrade both power supplies. Follow these procedures for one power supply, then immediately upgrade the other power supply. Mixing a two-input 160-A power supply and a three-input 240-A power supply is supported only during the upgrade.

The power supplies are located at the lower rear of the chassis. Each power supply is hot-insertable and hot-removable. When one power supply is powered down or removed, the other power supply automatically assumes the entire electrical load for the routing node. To upgrade each two-input 160-A power supply to a three-input

240-A power supply, use the following procedures:

Preparing the DC Power Cables

The accessory box shipped with the installation kit includes the cable lugs that attach to the terminal studs of each power supply (see Figure 25 on page 46).

CAUTION: Before the power supply installation begins, a licensed electrician must attach cable lugs to the power cables that you supply. A cable with an incorrectly attached lug can damage the power supply.

Tools and Parts Required

To upgrade the power supplies, you need the following tools and parts:

Four additional DC power cables (two cables for each power supply)

Electrostatic discharge (ESD) grounding wrist strap

7/16-in. nut driver or pliers
