4.5 The VB200/VB200-DC Hardware (VB220)
In the cases where redundant power supplies are not required the VB200 and VB200-DC chassis options
are suitable.
Each VB200 or VB200-DC unit consists of a 1RU chassis with 3 option slots. The unit can be equipped
with either a 100–240V AC power supply (VB200) or a –48V DC power supply (VB200-DC). The unit is
forced air ventilated, the air flow going from left to right as seen from the connector side of the unit. The
maximum power consumption of the chassis with optional modules is 50W. By default all connectors and
the power plug are located at the front of the unit. However the rack ears of the chassis may be moved to
provide for rear mounting of the unit. The rack ears are designed to support the weight of the unit.
