Figure 3-55 Base Station Power Supply via Three
Additional UPSC-D power supply via an external power supply unit
If the power supplied by the UPSC-D (HiPath 3550) is insufficient, additional power can be sup-
plied by installing the external power supply (Powerbox PB3000). To do this, connect the DC
port on the PB3000 to the special DC input on the UPSC-D.
As described on the preceding pages, the base stations must be connected to free U
faces. BS3/1 needs one, BS3/2 needs two, and BS3/3 needs three free U
Powerbox PB3000 is also used if an external power supply unit is required for HiPath 3500 or
HiPath 3300 (19-inch housing).
Section 11.4, "Power-Related Capacity Limits" shows which telephone configurations manage
without an additional power supply and which configurations require an additional one.
