Table 3-1 Configuration of the cabinet

Component Configuration

Power Distribution Box Only one power distribution box is

configured.

Subrack l The MPR is configured with one

main processing subrack (MPS) and

depending on the traffic volume zero

to two extended processing subracks

(EPSs).

l The EPR is configured with one to

three EPSs, depending on the traffic

volume.

Air Defence Subrack Two air defence subracks are

configured.

Independent Fan Subrack Only one independent fan subrack is

configured in the N68E-22 cabinet and

no independent fan subrack is

configured in the N68E-21-N cabinet.

Rear Cable Trough Three rear cable troughs are configured.

NOTE

l The subracks are numbered from bottom to top, and the MPS is numbered 0.

l The components of the N68E-21-N cabinet are the same as those of the N68E-22 cabinet, except that the

N68E-21-N cabinet is not configured with the independent fan subrack.

3.4 Technical Specifications of the Cabinet

The technical specifications of the cabinet consist of cabinet dimensions, height of the available

space, cabinet weight, rated input voltage, input voltage range, Electromagnetic Compatibility

(EMC), power consumption, and heat dissipation.

Technical Specifications of the BSC6900 Cabinet (N68E-22)

The BSC6900 uses the Huawei N68E-22 cabinet or N68E-21-N cabinet. The two models of

cabinets have different technical specifications.

Table 3-2 describes the technical specifications of the BSC6900 cabinet (N68E-22).

Rated input voltage -48 V DC power supply

Input voltage range -40 V to -57 V

EMC l Meets the requirements in ETSI EN300 386

l Meets the requirements in Council directive 89/336/

EEC

Power consumption The cabinet power consumption equals the sum of power

consumption of all subracks in the cabinet.

It is recommended that the power distribution system

provide a maximum of 5100 W power per cabinet to

facilitate capacity expansion.

Heat consumption The heat generated by a cabinet equals the total heat

generated by all subracks in the cabinet.

To facilitate capacity expansion in future, the air

conditioning system installed onsite must be able to

dissipate a maximum of 4100 W heat from each cabinet.

Heat dissipation A fan and air defense frames are installed in a BSC cabinet.

Air flows in from the bottom of the cabinet and flows out

from the top of the cabinet, ensuring good heat dissipation.

WARNING

When the voltage of power supply is lower than the lower threshold of the input voltage scope,

multiple boards will become abnormal at the same time.

Therefore, check the power system if multiple boards are abnormal at the same time.

NOTE

An empty cabinet refers to the one that is configured with front and rear doors, side panels, a power

distribution box, and a set of cables.

WARNING

When the voltage of power supply is lower than the lower threshold of the input voltage scope,

multiple boards will become abnormal at the same time.

Therefore, check the power system if multiple boards are abnormal at the same time.

3.5 Cable Connections of the Cabinet

This section describes the connections of the power cables, PGND cables, and signal cables in

the cabinet.

NOTE

The BSC6900 uses the Huawei N68E-22 or N68E-21-N cabinet. Only the Huawei N68E-22 cabinet requires

the independent fan subrack. The MPR and EPR mentioned in this section are of the N68E-22 model.

3.5.2 Connections of Power Cables and PGND Cables in the Cabinet

The power cables in the cabinet are used to connect the power distribution box to the subrack

and independent fan subrack, thus ensuring stable power supply to the subrack and independent

fan subrack. The PGND cables are used to connect the cabinet to the grounding bar in the

equipment room, thus protecting the cabinet from electrostatic discharge.
