2.3 Hardware installation
Rail-mount system
The rail-mount system can be used to mount the DTE-3114 on a DIN rail (TS32, TS35). The rail can
be mounted directly on a wall, or the DekTec 19”-rack-mountable rail can be used to install up to
12 DTE modules in 3U-height 19” rack space. Special consideration is required to avoid
overheating of the unit, see section 2.4.
Network connection
A standard Cat5 (or higher) patch cable can be used to connect a DTE-3114 to the network. Either a
straight-through or cross-over network cable can be used; the type of cable will be automatically
recognized (auto-MDIX operation). The DTE-3114 will automatically select the link speed of the
connected network (10/100/1000Mbps).
Power
The DTE-3114 can be powered from the network using Power over Ethernet (PoE). Alternatively,
when the switch supports Ethernet without PoE, a 24V/400mA power adapter can be applied using
the auxiliary 24V DC power jack. If both PoE and auxiliary power are supplied, the DTE-3114 will
use auxiliary power.
Note: Switching between the power supplies (e.g. connecting auxiliary power while the unit is
operational in PoE mode) can cause a restart of the DTE-3114.
RF outputs
The DTE-3114 has a 75-Ω main RF output and a 75-Ω RF monitoring output. The RF level of the
main output can be configured by the user to a power level between -32 and -9dBm; The RF level of
the monitor output (-25.5dBm) is not adjustable.
Reset button
When the DTE-3114 is operational and the reset button is hold down for approximately one second
the device will reboot and the device will obtain an IP address through DHCP (even if a static IP
address was configured). This should be required in exceptional cases only, because the DTE-3114
has an internal watchdog function that automatically resets the device if the software crashes.
