3.2 Components of the Cabinet Based on functions, cabinets are classified into the main processing rack (MPR) and extended processing rack (EPR). The components of the MPR are the same as those of the EPR. The components are subracks, air defence subrack, and rear cable troughs.
Classification of Cabinets Based on the logical functions of subracks configured, cabinets are classified into the main processing rack (MPR) and extended processing rack (EPR). The MPR is configured with main processing subracks (MPSs) and extended processing subracks (EPSs), but the EPR is configured only with EPSs. An MPS and an EPS have the same physical structure but are configured with different boards. Specifically, an MPS is configured with the OMU and GCU, whereas an EPS is not configured with the OMU or GCU. Only one MPR is configured in the BSC6910. The number of EPRs to be configured depends on the traffic volume, but only one EPR can be configured in the BSC6910. You can also choose not to configure the EPR. Figure 3-2 shows the components of a BSC6910 cabinet (N68E-22).

range Power consumption
The maximum power consumption of a subrack is 4000 W. Currently, the cabinet power consumption is rated at 7100 W through hardware and software configurations, preventing the high density of power from affecting heat dissipation. It is recommended that the power distribution system provide a maximum of 4000 W power per subrack and 7100 W power per cabinet to facilitate capacity expansion.
Heat consumption
It is recommended that the air conditioning system dissipate a maximum of 4000 W heat per subrack and 7100 W heat per cabinet to facilitate capacity expansion.
Heat dissipation
Fans, air deflectors, and an air defense frame are installed in a BSC cabinet. Each subrack has separate air channels where air flows in from the front and flows out from the rear, ensuring good heat dissipation.
An empty cabinet is configured with front and rear doors, side panels, and a set of cables.
When the voltage of power supply is lower than the lower threshold for the input voltage, multiple boards may become abnormal at the same time. Therefore, check the power system if multiple boards become abnormal at the same time.
3.4 Cabinet Cable Cabinet cables consists of cabinet power cables, PGND cables, and cabinet signal cables.
3.4.1 Relationship Between the PDF and Subracks This section describes the relationship between the power outputs on the Power Distribution Frame (PDF) and the inputs of the subracks configured in a cabinet. The power outputs on the PDF connect to the power inputs on each subrack of the BSC6910. In each subrack, there are two power entry modules (PEMs). On each PEM, there are two power inputs. As shown in Figure 3-3 and Figure 3-4, PDF output area A consists of PDF outputs 1 and 2, and PDF output area B consists of PDF outputs 3 and 4.PDF output areas A and B work in active/standby mode. The BSC6910 power supply principles are as follows:

BSC6910 GSM Hardware Description
3 Cabinet
The PDF provides two power sources (one active and one standby) for the equipment and one PGND connection for each cabinet.
PEM 00 and PEM 01 work in active/standby mode and connect to the active and standby power sources, respectively. PEM 00 and PEM 01 work concurrently in normal cases. If either of them becomes faulty, the other PEM continues to supply power to the system to ensure stable operation. Therefore, you can rectify one faulty power input when the power is properly supplied, improving the reliability and availability of the power supply system.
The two power outputs of PEM 00 work in load sharing mode. The subrack that houses PEM 00 can work properly only when the two power outputs of PEM 00 are normal. The working principle of PEM 01 is the same as that of PEM 00.
Figure 3-3 shows the relationship between power outputs and inputs when only one subrack is configured in a cabinet. Figure 3-3 Relationship between power outputs and inputs when only one subrack is configured
Figure 3-4 shows the relationship between power outputs and inputs when three subracks are configured in a cabinet.

(1) Front slot
(2) Backplane
(3) Rear slot
Each subrack provides a total of 28 slots. The 14 slots on the front side of the backplane are numbered from 00 to 13, and those on the rear side from 14 to 27.
Two adjacent slots, such as slots 00 and 01 or slots 02 and 03, can be configured as a pair of active/standby slots. A pair of active/standby boards must be installed in a pair of active/standby slots.
The pair of active/standby boards installed in the active/standby slots must be of the same type. For example, if slots 14 is configured with GCUa board, slots 15 must be configured with GCUa board.
Different types of boards can be installed in non-active/standby slots. For example, if the GCUa board is installed in slot 15, the EXOUa board can be installed in slot 16.
Each slot provides a different switching bandwidth. A board must be configured in a slot with sufficient bandwidth. Figure 5-5 shows the switching bandwidth of each slot when the subrack is configured with two SCUb boards.

Description
1-5
Bits 1 to 5 are used to set the subrack number. Bit 1 is the least significant bit. If a bit is set to ON, it indicates 0. If a bit is set to OFF, it indicates 1.
6
Odd parity check bit
7
Reserved, undefined, generally set to ON
8 (the most significant bit)
Startup type of the subrack, must set to OFF
You must set the DIP switch before powering on the subrack. The setting after the power-on is invalid.
DIP Switch Setting Principle The DIP switch uses odd parity check, so the number of bits that are set to OFF must be odd. The setting is as follows: 1.
Set bits 1 to 5 to appropriate values.
2.
Set bit 7 to ON.
3.
Set bit 8 to OFF.
4.
Count the number of bits that are set to OFF. −
If the number is even, set bit 6 to OFF.
−
If the number is odd, set bit 6 to ON.

7.3 Optical Fiber An optical fiber is used to connect an optical interface board to the Optical Distribution Frame (ODF) or another NE, or to interconnect SCUb boards. It is optional in the BSC6910. The number of optical fibers to be installed depends on site requirements.
Classification of Optical Fiber According to the types of optical connectors at both ends of the optical fiber, the optical fiber can be classified into the following types:
LC/PC-LC/PC single-mode/multimode optical fiber
LC/PC-FC/PC single-mode/multimode optical fiber
LC/PC-SC/PC single-mode/multimode optical fiber
In actual installation, the LC/PC optical connector at one end of the optical fiber is connected to an optical interface board in the BSC6910, and the connector type at the other end of the optical fiber depends on site requirements.
The SFP+ high-speed cable has two length specifications: 3 m (9.84 ft.) and 10 m (32.80 ft.). When the cabling distance between two subracks in different cabinets is longer than 10 m (32.80 ft.), the SCUb boards in the two subracks need to be connected using a multimode optical fiber. The SCUb boards inside the same cabinet are connected using SFP+ high-speed cables.
The LC/PC-LC/PC single-mode/multimode optical fiber connects an optical interface board to the ODF or another NE or interconnects optical interface boards.
In practice, two optical fibers form a pair. Both ends of each optical fiber in the pair are attached with temporary labels. If one end of the optical fiber is connected to the TX port, the other end should be connected to the RX port.
The TX and RX ends of each optical fiber must be connected correctly. Otherwise, the optical signals cannot be received or transmitted.
