System Setup
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 used.
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 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)
shielded 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.
Cabling guidelines
The Conference Units are connected to the CU
61xx Central Unit using Cat5e F/UTP or U/FTP
shielded 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
•
’ is to be used. AWG26 cables 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 is 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
Diameter
Square
AWG22
0.64 mm
0.32 mm2
AWG23/1
0.57 mm
0.25 mm2
AWG24
0.53 mm
0.22 mm2
AWG26
0.42 mm
0.14 mm2
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.
