z Supporting -48 V DC and 110/220 V AC power supply |
|
z Providing at most 12 U space for user equipment when not |
|
configured with additional devices |
|
z Supporting internal storage batteries in the case of AC input |
|
z Supporting piled installation with the storage battery cabinet |
|
(under the APM30 cabinet), which is optional |
|
|
DCDU |
The DCDU is a power distribution box and supports one DC |
|
input and nine DC outputs. |
|
|
EMUA |
The EMUA is an environment monitoring unit and implements |
|
monitoring for the site environment and user equipment. |
|
For details on the functions of the EMUA, see the EMUA User |
|
Guide. |
|
|
SLPU |
The SLPU is a lightning protection unit, which is used to |
|
configure the UELP and UFLP. It implements lightning |
|
protection for E1/T1 and FE/GE signals. |
|
|
DDF |
DDFs are classified into two types, which are used for coaxial |
|
cables and twisted-pair cables respectively. A DDF is required |
|
when the transmission equipment and BBU3900 are configured |
|
in the same cabinet. |
|
|
DC power system |
Made up of PSUDC/DC modules, the DC power system converts |
|
+24 V DC input to -48 V DC output. |
|
|
AC power system |
Made up of PSUAC/DC modules and PMU modules, the AC |
|
power system converts 220/110 V AC input to -48 V DC |
|
output. |
