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.

The main and redundant power supply 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.

For instructions on hot swapping, refer to “Hot Swapping a Power Supply” on

page 25.

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.
