10.2.2.10. Information on the 19“ AP 3500 IP Access Point 
Figure 17 “AP 3500 IP - front view”
shows the front view of a AP 3500 IP. The shelf can be mounted in a 19“
rack using additional angle brackets and has a height of 3HE.
There is space on the left for 4 modules and the topmost slot is allocated
to the HG 3575 (NCUI2/4). Peripheral modules of the OpenScape 4000 can
be inserted into the other slots. These modules are covered by a metal
panel that is inserted separately. In the figure, this panel has been
removed from the bottom slot.
At the rear, either the usual main distribution cables can be attached
or plug-in patch panels can be used to connect the devices directly using
Western plugs.
In addition to the modules, the rack also contains 2 power supply
modules on top of one another. The AP 3500 IP can be operated using a
power supply module. A second may also be operated as a redundant unit.
A ventilator module is located at the right-hand side. Because the
modules are in a horizontal position, the system has to be forced ventilated.
IMPORTANT:
The ventilation openings on the left and right-hand
side of the housing must not be obstructed. The operating position of
the equipment is horizontal.
Figure 182. AP 3500 IP - front view
The AP 3500 IP can be extended by four slots using a AP 3505 IP with
a similar structure (no HG 3575 in the AP 3505).
Special features
- The AP 3500 IP represents the left and the optional AP 3505 IP represents the right half of a conventional shelf.
- The slots are counted from bottom up and are numbered 1,2,3 and 4 in the AP 3500 IP (4 is HG 3575), and 5,6,7 and 8 in the optional AP 3505 IP.
- Boards with front connectors can only be used if they are fitted with a suitable metal panel (for example, STMI2, DIUN2 starting with status -X-7, SLC24 starting with status -X200-9, PBXXX starting with status -X-F3, ...)
- SIVAPAC modules with adapters are not supported, because they do not fit under the shielding cover. As an exception, a number of these boards are fitted with a new plastic panel C39228-A402-C21. (TMEW2, SLMA,TMDID,TMEMUS).
