5.1 Chassis Ground
Warning: Failure to follow these steps may result in equipment damage, personal injury, and void the
product warranty.
To help prevent electrical shock, the separate, protective earthing terminal located next to the power jack on
the rear panel (See Figure 2 item 10) must be permanently connected to earth using 18 AWG wire or larger.
5.2 Power-Up Sequence
Connect the unit’s Network port to an Allworx server LAN. Then connect the AC power adapter. The Port
Expander will automatically begin to power up. As it progresses through the power up sequence, the front
panel Power LED will flash green. If a network connection has been made and when the unit is ready, the
Power LED will shine steady green.
If no network connection has been made prior to when the unit is powered on, the Power LED will change from
flashing green to solid amber. Solid amber indicates that the unit is in Configuration Mode.
