VPort 2140 User’s Manual Introduction
1-6
5: 75 Ohm DIP Switch
There are four 75 Ohm DIP switches numbered from “1” to “4” on the front panel. They are used
to enable the 75-Ohm resistance video impedance. DIP switches should be turned to the “ON”
position if cameras are connected to the video inputs. If users want to connect another device to
the video output, such as a VCR or multiplexer, the switches should be turned to the “OFF”
position to disable the impedance.
6: System LEDs: “POWER,” “CONNECT,” and “SERIAL”
Each time the Video Server starts up, it will perform a Power-On-Self-Test (POST) to examine
each hardware module. VPort 2140 has 3 LEDs:
a. POWER: power indicator
b. CONNECT: checks if the Video Server is alive
c. SERIAL: checks if the RS-232/485 COM ports are in use
As soon as the administrator plugs in the power connector, both the CONNECT and SERIAL
LED’s will flash, one by one, until the diagnosis is finished. If the result is good, these 2 LEDs
will turn off momentarily, and then follow the pattern shown in the table below. If any of the
modules fails, refer to Chapter 7, Troubleshooting, under Power On Self Test for the error
pattern, and then follow the troubleshooting procedures. If the system still does not operate
normally, please contact your reseller for technical service.

OFF: Network not alive
LINK Check the 10/ 100 Mbps Ethernet speed ON: 100 Mbps
OFF: 10 Mbps
FDX Check if transmission is full or half duplex ON: Full Duplex
OFF: Half Duplex
