Power supplies
The ships with one or two power supplies, depending on how it was ordered from
the factory.
v The B08S comes with one 12-volt AC System (SYS) power supply. You can

install up to eight power supplies in the B16S; four 12-volt AC system (SYS)
power supplies and four 48-volt AC power supplies for POE.
You can use any combination of the supported AC supplies in the same device.
Note the following regarding POE power supplies:
v The 2500W 220V POE Power Supply requires 220-volt input.
