Optional Installation - Mid-Mounting; Powering Up The Unit - BridgeTech VB20 User Manual

4.8.3 Optional Installation - Mid-Mounting

The Enhanced Chassis allows rack ears to be mid-mounted. This can be convenient if
the chassis is installed in a telco environment. Unscrew the six size 2 Phillips screws
holding the rack ears, and move the six screws covering the mid mounting holes to
the front mounting holes. Remount the rack ears at the middle of the unit.

4.9 Powering up the Unit

For the VB220 once the chassis is securely mounted and signal cables are connected,
it can be powered up by connecting the power cable to a mains source. When the
power cable is connected the power LEDs of the individual optional modules should
light up and the chassis fans should operate.
For a DCC unit (-48V power supply) the shipped 3-PIN D-sub(15) plug should be
soldered to the power cable prior to power-up. Refer to section 5.3 for a description of
this plug.
For the VB20 it is just to connect the mains source and the diodes should light up.
Note that it will take some time from power-up until the modules can be accessed via
the management interface – typically the start-up may take up to two minutes.
