are discussed in the VS2000 VS-Link Installation and
Configuration Guide:
• Backup server
• “Hot-swapping”
• Individual modem reset capability
• Terminal program (WCOM32)
• Port Monitor program (PORTMON)
See the VS2000 VS-Link
Configuration Guide for information about installing
the software for this product and for reference
information for the AT command set.
™ Installation and
Installing VS2000 Hardware
Use the following procedure to connect the VS2000.
1. Record the model and serial numbers of the VS2000.
Serial Number* VS2000 Network Address*
00 C0 4E
* Identification tags are located on the back panel. You can
write this information on the blank sticker shipped with the
VS2000.
2. Optionally, mount the VS2000 into the rack using
the enclosed mounting brackets. The unit is
designed to install in the rack with the front or back
of the unit facing the front of the rack.
Warning: If mounting the VS2000 into a rack mount
3. Connect the cable from the appropriate Ethernet
connection (10Base-T or AUI) on the VS2000 to your
server or Ethernet hub.
Note: If connecting the VS2000 directly to the server, an
unit, make sure the rack is not top heavy.
Ethernet crossover cable is required.

Power-On Diagnostics
When you switch a VS2000 on, it performs a selfdiagnostic. The results are displayed via the LED lights
on the back panel. If the unit is working correctly, the
following events should take place:
1. Turn the power switch to the On position.
2. All LEDs should light up briefly, to show that they
are working.
3. Both 10Base-T lights should remain lit after the
port LEDs go out, while the unit establishes the
Ethernet connection and polarity.
4. If using 10Base-T cabling, the lower LED remains
lit to indicate that the Ethernet connection is
established and polarity is correct.
5. The Port 2 LED begins flashing, to indicate that the
VS2000 is waiting for the server to initiate VS-Link
communications.
Note: The following steps only occur after you have
installed the VS-Link software. Use the VS2000
VS-Link Installation and Configuration Guide for
software installation information.
After installing the software, turn off the VS2000
and verify the full diagnostics sequence.
6. The upper 10Base-T LED flashes briefly, as the
server acquires control of the VS2000.
7. The port LEDs begin flashing in a “sweeping”
sequence, to indicate that the unit is operating
normally.
Note: See the following tables if you are not seeing the
LED sweeping sequence activity.

properly or it is connected to the AUI
port.
Ethernet Crossover Cable
If you are connecting from the VS2000 10Base-T
connector directly to the NIC card in the server, you
need a crossover cable, wired as follows:

Modem Cables
The VS2000 modem ports use standard telephone-type
unshielded twisted-pair cables with RJ11 modular
connectors. These cables can be purchased anywhere
commercial or consumer telephone products are sold.

which can be determined by turning the equipment off
and on, you are encouraged to try and correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the equipment and
the receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV
technician for help.

VS2000 - Canada
The VS2000 connects directly to off-premises Common
Carrier facilities using the standard two-wire telephone
connection. In some cases, the building’s inside wiring
associated with a single line individual server may be
extended by means of a certified connector assembly
(telephone extension card).
NOTICE: The Industry Canada label identifies certified
equipment. This certification means the equipment
meets telecommunications network protective,
operational, and safety requirements as prescribed in the
appropriate Terminal Equipment Technical
Requirements document(s). The Department does not
guarantee the equipment will operate to the user’s
satisfaction.
Before installing this equipment, users should ensure
that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment
must also be installed using an acceptable method of
connection. The customer should be aware that
compliance with the above conditions may not prevent
degradation of service in some situations.
Repairs to certified equipment should be coordinated by
a representative designated by the supplier. Any
repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the
telecommunications company cause to request the user
to disconnect the equipment.
Users should ensure for their own protection that the
electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe
system, if present, are connected together. This
precaution may be particularly important in rural areas.
CAUTION: Users should not attempt to make such
connections themselves, but should contact the
appropriate electric inspection authority or electrician,
as appropriate.
NOTICE: The Ringer Equivalence Number (REN)
assigned to each terminal device provides an indication
of the maximum number of terminals allowed to be
connected to a telephone interface. The termination on
an interface may consist of any combination of devices,
subject only to the requirement that the sum of the
Ringer Equivalence Numbers of all the devices does not
exceed 5.
This digital apparatus meets the Class A limits for radio
noise for digital apparatus set out in the interferencecausing equipment standard entitled: “Digital
Apparatus,” ICES-003 of Industry Canada.
When connecting the VS2000 to the telephone service,
avoid contact with the telecommunications lead wire.
Grasp the insulated part of the jack, and do not contact
the back of the circuit board. Telephone wiring can carry
dangerous voltages from electrical faults or lightning.
External Wiring
Any external communications wiring you may install
needs to be constructed to all relevant electrical codes.
In the United States this is the National Electrical Code
Article 800. Contact a licensed electrician for details.
