The VE8021 is designed for wall or table
mounting.
The VE8021R is designed for 19” rack
mounting (1U).
Table:
Provided with the VE8021 are four rubber
pads. Peel pads off their carrier backing and
place at the four corners of the bottom of the unit.
Wall:
Secure mounting brackets with screws
provided to the VE8021, then secure the VE8021
to the wall. See Figure 1.

Power Connections
The preferred method of powering a
VE8021/VE8021R is via a Power over Ethernet
(PoE) switch meeting the 802.3af specification.
If the rear panel barrel connector is used for
power, the preferred power supply is a Valcom
VIP-324.
Make all required signal connections before
applying power to the unit. If powering via
802.3af, make sure all signal connections via the
rear panel are made then connect the
VE8021/VE8021R to the Ethernet switch.
If power is supplied via the barrel connector,
make sure all signal connections are secure.
Attach the unit to the network via the front panel
RJ-45 Ethernet connector. Apply power by
plugging the power supply in to the
VE8021/VE8021R via the barrel connector on the
rear of the VE8021/VE8021R.
Network Connection
The VE8021/VE8021R has one CAT-5 RJ-45
network connector on the front panel.
Use the supplied CAT-5 patch cable to connect
the VE8021/VE8021R to an Ethernet switch. If
the Ethernet switch is 802.3af compliant the
VE8021/VE8021R will draw power from it.
Signal Connections
On the rear panel, the VE8021/VE8021R has 3
signal connectors on the rear panel:
1 RJ-11 jack for connection to a FXS circuit
1 RJ-11 jack for a failover telephone
connection
1 terminal block for relay connections
