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.
