Overview

Power Supply The PowerBlade PBC18 can be either an AC or DC powered chassis. The

expansion slot for the main power supply and the optional redundant

power supply are located on the back of the chassis. Refer to Figure 2 on

page 20.

The main and redundant power supplies can be “hot swapped,”

meaning that should either power supply fail, the failed power supply

can be removed and replaced with a new power module while the

chassis is operating. Network operations will not be interrupted. The

power modules to be hot swapped must be the same type. For example,

both power supplies must be AC or both must be DC.

Powering ON or OFF the chassis depends on the type of power supply

installed. For an AC model, you connect or disconnect the power cord.

For a DC model, you connect or disconnect the DC power cables or

power OFF the DC circuit to which the power supply is connected.

To install a power supply, refer to Installing a Power Supply Module on

page 33. For instructions on hot swapping, refer to Hot Swapping a

Power Supply on page 42.

AC Power Supply

The AC power supply operates at 100-120/200-240 V AC with an input

frequency of 50/60 Hz at ± 3%. Figure 3 shows an PowerBlade PBC18

with an AC power supply.
