Optical cable:
Optical cable supporting 1 Gbps must be used to interconnect PhoeniX G2 IDU and EMM (ASI
or E1) modules. Either Single-mode or Multi-mode optical fiber can be used. The same type
SFP modules have to be installed in both devices PhoeniX G2 IDU and EMM. In order to
interconnect two Phoenix G2 IDUs for 1+1 Full redundancy configuration 2.5 Gbps optical
cable and SFP modules must be used.

Powering Phoenix G2 IDU/ODU
Next step is to interconnect LLM IDU DC power connector with power source using power
cable. In case AC/DC Power supply, 48VDC, 80W (EU - P/N I0AB4810, US – P/N I0AB4811,
AUS - I0AB4818) provided by SAF Tehnika JSC is used to power up PhoeniX G2 IDU,
interconnect IDU and power source through appropriate connectors. Otherwise perform the
following steps to ensure that PhoeniX G2 IDU is powered up correctly:
1.
It is necessary to interconnect PhoeniX G2 IDU DC power connector (located on left
side of front panel) with power source. For this purpose power cable is required. Any 2
wire power cable of good quality which fits well in SAF Tehnika’s supplied 4 pole
“screw on” power connector could be used. The power cable connector is 4 pole, type
2ESDV-04. This connector has screw clamp terminals that accommodate 24 AWG to
12 AWG wire. The recommended wire size for construction of power cables under 3
meters in length, supplying 48 V DC, is 18 AWG. The opposite end of the power cable
should have a termination appropriate for the power supply being used. The power
cable should be of sufficient length to avoid tension in the cable and provide a service
loop for connection, but not be of excessive length. Using the power cable connector
of type 2ESDV-04, pins 1/2 (labelled ‘-‘) should be connected to the power supply
terminal supplying 48 V DC, while pins 3/4 (labelled ‘+’) should be grounded. Refer to
Figure 2.10
.
Note that pins 3/4 (‘+’) of the PhoeniX G2 IDU DC Power connector (
Figure 2.10
) is connected
to the IDU chassis ground internal to the IDU. Use of a power supply with an inappropriate
ground reference may cause damage to PhoeniX G2 IDU and/or the power supply.
2.
Connect the power cable to the 48 V DC power supply, and place the voltmeter probes
at the unconnected ends of the power cable, with the positive voltmeter probe on pin
1/2 (’-’) of the cable connector and the negative probe on pin 3/4 (’+’). The connector
screw terminal screw heads may be used as convenient monitor points. Refer to
Figure 2.10
.
3.
Turn on the –48 V DC supply. Verify that the digital voltmeter reads between 36 V DC
and 57 V DC when monitoring the cable points specified above. Adjust the power
supply output voltage and/or change the connections of the power supply to achieve
this reading.
4.
With the negative voltmeter probe still on pins 3/4 (’+’) of the power cable connector
(and the power supply still on), put the positive voltmeter probe to the PhoeniX G2 IDU
