General Guidelines
Installation
The EX 6010 is suitable for either table-top or 19-inch
rack-mounted use. 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 6105
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" racks to be
Cabling guidelines
The Conference Units are connected to the CU 6105
Central Unit using Cat5e F/UTP or U/FTP screened
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
EX 6010, 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 using EX 6010 or a RP 6004 Repeater in a
•
chain). This includes interconnection cables
between the units.
Maximum cable length in one chain when using
EX 6010 or RP 6004 Repeaters and Cat5e cables
•
is 680 m.
Cables must be AWG24 if the number of units in
the tables in section '0 Max. number of units to be
•
connected' is to be used. AWG26 cables will not

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 EX 6010 to the various DCS 6000 units
using CAT5e cabling (F/UTP or U/FTP) screened
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.
•
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 EX 6010 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.

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:
