Valcom VE8002B Manual page 3

Rack: Two VE8002B units may be joined together
and installed into a 1U rack slot. Using Figure 3 as
a guide, attach the interlock brackets and end
mounting brackets to each of the VE8004B units,
then mount the combined units into an available
rack slot.
Table: Provided with the VE8002B are four rubber
pads. Peel pads off their carrier backing and place
at the four corners of the bottom of the unit.
VE8002BR
Rack: Secure mounting brackets as shown in
Figure 4, to the VE8002BR. Place the VE8002BR
into a standard 19" rack (1U) and secure to rack
with proper hardware (not included).
Power Connections
The preferred method of powering a
VE8002B/VE8002BR is via a Power over Ethernet
(PoE) switch meeting the 802.3af specification.
Make all required signal connections before
applying power to the unit. If powering via 802.3af,
make sure all signal connections via the back
panel are made then connect the
VE8002B/VE8002BR to the Ethernet switch.
If the rear panel barrel connector is used for power,
the preferred power supply is a Valcom VIP-324D.
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 into the
VE8002B/VE8002BR via the barrel connector on
the rear of the VE8002B/VE8002BR.
Network Connection
The VE8002B/VE8002BR has one CAT-5 RJ-45
network connector on the front panel.
Use a standard Ethernet patch cables to connect
the VE8002B/VE8002BR to an Ethernet switch.
Status Indicator Lights
The VE8002B/VE8002BR has 3 status indication
lights on the front panel:
STATUS: Illuminates at regular intervals during
normal operation. On steady indicates unit is in
reset mode.
The network jack provides two LED indicators:
Green LED: (Link) Indicates Ethernet connection
when illuminated.
Yellow LED: (Activity) Indicator flashes to indicate
network activity.
Signal Connections
The VE8002B/VE8002BR has 3 signal connectors
on the rear panel:
 1 RCA jack for AUX audio input
 2 RJ-45 connectors for signal connections for
each networked channel
AUX Input: Local audio may be input via the
rear panel RCA jack. Nominal input impedance
is 600 Ohms. Connect any compatible audio
source using an RCA patch cable. Audio
supplied through the rear panel RCA jack is
transformer coupled to the Audio Out channels
when Audio Out is idle. This is typically
used for background music.
Networked Channels: Access to the networked
audio output, audio input, contact closure input and
relay closure output is provided via two rear panel
RJ-45 connectors. Provided with the
VE8002B/VE8002BR are two 3 foot RJ-45 patch
cables and two VM-186 RJ-45 connectors. Signal
connections are made by connecting one end of a
patch cable to the VE8002B/VE8002BR and the
other end of the patch cable to the VM-186
connector. Access to the signals is via screw
connections or 110-style punchdown block on the
VM-186. Signals are present on pairs of pins. (See
Figure 1).
