4.5.2 Replacing a BBU

WARNING

Always use both hands when removing or replacing an SBB, to fully

support its weight.

To replace a BBU in slot 6, complete the following procedure:

1. Press the two mounting tabs to release the unit, and slide the unit out of the

shelf.

2. Insert the replacement unit in the guide slots and push it in until the tabs

lock in place.

3. Observe the LEDs and ensure the BBU is charging as speciﬁed in Table 2–2.

The BBU should be fully charged in approximately 1 hour.

4.6 Power Cords and Cables

Each BA35X–HA universal input ac power supply requires an individual ac

power cord that is compatible with an International Electronic Committee (IEC)

C–14 shrouded ac receptacle connector. These cords are part of the enclosure and

are listed in the enclosure documentation.

CAUTION

Input ac power must be routed through the enclosure cable distribution

unit. This ensures proper line voltage protection for the supply. Do not

connect an ac supply directly to a wall outlet.

Each BA35X–HB universal input dc power requires an individual dc power cable

that has a plug receptacle (Molex part number 39–01–2060) and six female

pins (Molex part number 39–00–0055). The receptacle wiring is described in

Table 4–4.
