DCS 6000 Digital Conference System

General Guidelines

Installation

The CU 6110 is suitable for either tabletop or 19-
inch rack-mounted use. Four feet (for tabletop
use) and two mounting brackets (for rack
mounting) are supplied.
When installing in a 19" rack the supplied 19"
brackets shall be fixed to the front side of the CU
6110 Central Unit by unscrewing the crews
holding the top and button cover and then fix the
brackets using the same screws.
The unit has a low noise built-in fan taking air in
at the left side of the unit and blowing the hot air
out at the right side. That allows units in 19"

Cabling guidelines

The Conference Units are connected to the CU
6110 Central Unit using shielded CAT5e (F/UTP or
U/FTP) cables and the following guidelines have to
be observed:
•
The conference units are daisy chain connected
to the central unit
•
The number of units, which can be connected
to CU 6110, depends on length of the feeding
cable and the length of the cable between each
unit.
If the feeding cables are short and the cables
between the units are short, more units can be
connected than if the feeding cable is long
and/or the cables are long between the units.
•
Maximum cable length in one chain is 200 m
(before inserting RP 6004 Repeater in a chain).
This includes interconnection cables between
the units.
•
Maximum cable length in one chain when using
RP 6004 Repeaters and Cat5e cables is 680 m.
•
Cables must be AWG24 if the number of units
in the tables in section 'Max. number of units
to be connected' is to be used. AWG26 cables
racks to be stacked close with other units without
extra room for cooling air between them. Please
check that other units in the rack will allow this.
Connect the CU 6110 to the various DCS 6000
units using shielded CAT5e (F/UTP or U/FTP)
cables following the guidelines in the next
chapter.
The operation and installation of the various DCS
6000 units is found in the User Manuals for the
specific units.
will not allow as many units. DIS cables
series EC 6001-xx are all AWG 24.
•
It is desirable that the square of the feeding
cables are as big as possible to minimize the
voltage drop in the cables. Cat5e cables are
delivered in various gauges:
The following table shows the
Diameter/square for various AWG types:
Type
AWG22
AWG23/1
AWG24
AWG26
Although the DCS-LAN chain output connectors
have a 125 W supply, this 125 W power is not
all available with long cables, as there will be a
power drop in the feeding cable from the CU
6110 Central Unit to the units connected.
Please consult the next sections for details
about the number of units, which can be
connected depending on the cable length.
