TPRF
Mounting the TPRF31 on a rack
Firstly, insert the sub-rack into the cabinet, and apply 4 screws (not
provided) in order to fi x it (Fig. 4.2.11).
To correctly install the TPRN, the distance between the front door
of the rack and the front side of the TPRF31 should be at least
15cm, otherwise optical cables and any eventual RF cables might
be damaged when the cabinet door is closed.
Leave at least 1HE distance between the TPRF31 Fast MiniRack
and any other subrack element, in order to facilitate air
circulation.
Leave at least a 1HE of free space between the bottom or the top
of the cabinet and the TPRF31s.
Mounting the TPRF31 on a wall
After proper turning and fi xing of the brackets (according to that shown in Figure 4.2.10), drill
into the wall according to the layout in Figure. 4.2.13).
It is strongly suggested to mount the TPRF31 with the the power supplying ports (on the
TPRF31, front side, Fig. 4.2.7) turned upwards
Insert the 4 anchors into the holes you have just drilled, then fi x the TPRF31 fi rmly to the wall by
tightening the screws into the anchors.
TPRF31 Start-Up
Before switching on the TPRN sub-rack, make sure that:
• all the expected modules have been inserted
• the modules have been connected to each other by RF jumpers, according to what has
been planned during the system design
• every TFLN contained in the Master Unit has been connected to its TFAx Remote Units
• each TFAx Remote Unit has been connected to its coverage antennas
• the remote supervision unit (if present) has been connected or housed to the Master Unit
• different sub-racks have been connected to each other via an RS485 bus and each of
them have different addresses
• the rack housing the TPRF31 is large enough to leave a minimum distance of 1HE
between contiguous TPRF31 sub-racks
Remember that TFAx Remote Units should be switched on before relevant Master Units.
