MT56DSU-R Owner's Manual
2.4 Installation Procedure
After your CC216G modem rack has been installed in your computer
cabinet or in a stand-alone cabinet of your choosing, the MT56DSU-
R can be inserted into the rack. Refer to the Rack Mounted Modems
Owner's Manual for rack installation procedures. Then, perform the
following procedure in Table 2-2 to install the MT56DSU-R.
1.
Verify that the DIP switches on the MT56DSU-R are set for your
particular configuration; refer to Table 2-1.
2.
Before the MT56DSU-R is inserted into the modem rack, the
16-pin shunt on the back of the board needs to be in correct
position. If the MT56DSU-R is being connected to a RS232
interface, the 16-pin shunt needs to be placed in the "RS-232"
position. If the MT56DSU-R is being connected to a V.35
interface, place the 16-pin shunt in the "V.35" position.
3.
Determine which slot the MT56DSU-R board is going to be
placed in the rack. Apply the DSU LED sticker to the door, refer
to the Rack Mounted Modems Owner's Manual for the notes
about the CC216G.
4.
Open the door of the modem rack.
5.
Ensure that the MT56DSU-R board is positioned so that the
LEDs are toward the top of the board, insert the board in the
slot you have choosen to add the DSU LED sticker. The board's
gold edge connector will mate with the rack's backplane. The
edge connector is offset so that the board cannot be inserted
incorrectly.
6.
To connect the DTE to the MT56DSU-R using an RS232 cable,
connect the cable to the RS232 port on the DTE and the other
end to the DB25 connector on the back of the rack. Refer to the
Rack Mounted Modems Owner's manual for cable connections.
