Base Station Power Supply via Three U
P0/E
Interfaces
Connect the BS3/3 base station to three free interfaces on the SLC16N as shown in Figure 3-
74. Be careful not to exceed the maximum connection cable lengths (1000 m for 2x0.6 mm).
The use of three U
P0/E
interfaces increases the traffic capacity in the base station.
Additional UPSC-D power supply via EPSU2
If the power supplied by the UPSC-D (HiPath 3550) is insufficient, additional power can be sup-
plied by installing the external power supply EPSU2. To do this, connect the DC port on the
EPSU2 to the special DC input on the UPSC-D.
As described on the preceding pages, the base stations must be connected to one (BS3/1) or
two (BS2/2 and BS3/3) or three (BS3/3) free U
P0/E
interfaces on SLC16N.
If you need an additional external power supply for the 19-inch housing in HiPath 3500 or Hi-
Path 3300, you should use the EPSU2-R power supply. This is installed in the ECR expansion
cabinet rack (see Section 9.2.4).
Section 11.5, “Power-Related Capacity Limits” shows which telephone configurations manage
without an additional power supply and which configurations require an additional one.
