3.1.4 19-inch Rack Mounting for MP-124
MP-124 Gateway is supplied with brackets (‘ears’) fitted to each side of the enclosure so that the
MP-124 can be immediately installed in the 19-inch rack.
$ To install the rack mount MP-124, take the next 9 steps:
Step 1 Insert the MP-124 into the 19-inch rack, adjust it to the correct position and use two
standard rack-screws (not supplied) to secure each of the two brackets to the rack
frame.
Step 2 Insert each of the RJ-11 connectors on the 2-wire line cords of the POTS phones into
the RJ-11 sockets on the front of the MDF Adaptor Block
Up to 3,000 m (10,000 feet) of 24 AWG line cord can be used to connect telephones.
Step 3 Attach to the each of the sockets on the rear of the MDF Adaptor Block one pair of
wires from a 25-pair Octopus cable.
Step 4 Connect the wire-pairs at the other end of the Octopus cable to a male 50-pin Telco
connector. The pinout must be that shown in Table 3-1 and Figure 3-2 on page 24.
Step 5 Insert and fasten this 50-pin connector into the female 50-pin Telco connector
mounted at the rear of the MP-124 and labeled Analog Lines 1-24.
Step 6 Insert the RJ-45 connector of the 10/100 Base-T cable into the RJ-45 connector
mounted at the rear of the MP-124 and labeled Eth 1 for connection to your LAN.
Step 7 Connect an electrically grounded strap to the chassis ground screw on the rear of the
MP-124 and fasten it securely according to the current standards.
Step 8 Connect an electric power cord of the correct rating, from a grounded supply of the
correct voltage, into the power socket mounted at the rear of the MP-124 and labeled
100 - 250 V ~ 50 – 60 Hz 2A.
