Cabinet

Technique Feature

ZXSDR BS8900 is featured by the following items:

1. The cabinet is painted in light grey, pleasant to eyes.

2. The

cabinet design

is

technique oriented

with

reasonable

layout

and color arrangement.

3. The cabinet is waterproof treated, equipped with a heat-dis-

sipation window, a sun shield and a base against theft and

overall sealed for dust-proof.

4. The equipments all adopt bolts connection with lap seams filled

by shielding material to make every component well contacted

and spray coated after conduction oxidation.

5. Special requirements are made on the package of important

components. Prior protection should be taken to connectors

during overall cabinet transportation.

It is common to place the baseband power cabinet on a storage

battery cabinet or an RF cabinet, in which case a sun shield is

needed but the base is not necessary.

Heat

Exchanger

The heat exchanger has been installed inside baseband power cab-

inet before equipment consignment.

Judging from the feedback indices from temperature sensor, the

heat exchanger provides cooling or heating function to keep a sta-

ble temperature inside the cabinet and ensure the normal opera-

tion of equipments.

Confidential and Proprietary Information of ZTE CORPORATION 3

ZXSDR BS8900 Hardware Manual

The heat exchanger consists of extracting core, heater, external

ventilation fan, internal ventilation fan and control panel. Two air

channels (inner and outer) are set to implement air convection.

Figure 3 shows the heat exchanger structure.

Transmission

Equipment (Optional)

Transmission equipment is an optional configuration. The base-

band power cabinet reserves a space of 19" wide and 4 U high for

its installation.

The transmission equipment adopts - 48 V DC supply with 200 W

power consumption.

The transmission equipment completes transmission signals con-

version. ZXSDR BS8900 supports various types of transmis- sion

equipments, such as SDH, microwave, PDH optical transmis- sion

and HDSL.

Caution:

The transmission equipment demands a relatively small working

temperature range. Pay attention to the temperature in local en-

vironment for inside transmission equipment configuration since it

will decrease the BBU working temperature range.

Lightning

Subrack

The lightning subrack prevents the external RS232/RS485, dry

contact, E1/T1 and FE/GE interfaces of ZXSDR BS8900 out- door

transmission equipment from lightning and avoids damages to

the equipment caused by lightning induction and static electric-

ity.

The lightning subrack fulfills the following functions:

�

Supports lightning protection of 8 dry contacts.

�

Supports lightning protection of one RS232 channel and one

RS485 channel.

�

Supports lightning protection of 8 E1 channels.

�

Supports lightning protection of 2 FE/GE electrical interfaces.

The lightning subrack locates in the baseband power cabinet, an

option for configuration. Figure 6 shows the lightning subrack

panel.
