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
page 33. For instructions on hot swapping, refer to
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.
