2.3 Usage Scenarios of the APM30 and APM30H (Ver.A)

In outdoor scenarios, multiple cabinets and different configurations of cabinets can be used for a DBS3900 to meet various requirements for power backup, transmission, and capacity.

Cabinet Configuration Principles

NOTE

In this section, the APM is APM30 or APM30H (Ver.A), and the TMC is TMC or TMC11H(Ver.A). l A single DBS3900 can be configured with a maximum of 12 RRUs. If there are more than

12 RRUs, they must be configured in different base stations.

(40)

l A single APM supports only one TMC and a maximum of one integrated battery backup system with TEC (IBBS200T). TEC is short for thermoelectric cooling unit.

l A maximum of six power cables and twelve 2-wire fiber optic cables can be led out from a single APM.

l A single DCDU supplies power to a maximum of six RRUs.

l The APM or TMC can be installed on the floor or stacked on the battery cabinet. l A backup battery cabinet (BBC) or IBBS200T can be stacked with a cabinet of the same

type or be stacked under a TMC.

l If an extension cabinet such as a battery cabinet or transmission cabinet is required during an initial site deployment, the extension cabinet is placed on the left, and the basic cabinet is placed on the right. If both an extension battery cabinet and an extension transmission cabinet are required, the battery cabinet is placed on the left of the basic cabinet and the transmission cabinet is placed onto the battery cabinet or on the left of the battery cabinet. l Clearance must be reserved during an initial site deployment for future capacity expansion. In a capacity expansion scenario, the original cabinets are not relocated and new cabinets are added only to the right of the original cabinets unless they are required to be installed to the left of the original cabinets in exactly the reverse order of the original cabinets.

Requirements of Customer Equipment Specifications

Customer equipment to be installed in a Huawei cabinet must satisfy the following requirements: l Dimension requirements (as shown in Figure 2-6):

– The customer equipment must be 19-inch wide, which is the width of the standard equipment.

– The maximum depth of the customer equipment is 310 mm if the equipment supports natural ventilation or has air vents on the right and left; the maximum depth of the customer equipment is 280 mm if the equipment has air vents in the front and back. – A maximum cabling pace in front of the panel is 70 mm.

l Requirement for air vents:

– If the customer equipment has built-in fans, the fans must have air vents on the right and left or on the front and back so that wind blows from left to right or from front to back.

– If the customer equipment support natural ventilation, a minimum of 1 U slot must be reserved above and below the slot respectively for dissipation.

l Requirement for temperature

– In areas where the highest temperature is or is below 40°C, the customer must be able to function properly at –10°C temperature or even lower temperature and at 55°C or even higher temperature.

– In areas where the highest temperature is above 40°C, the customer must be able to function properly at –10°C temperature or even lower temperature and at 60°C or even higher temperature.

2.4 Usage Scenario of the APM30H (Ver.B) or APM30H

(Ver.C)

In outdoor scenarios, multiple cabinets and different configurations of cabinets can be used for the DBS3900 to meet various requirements for power backup, transmission, and capacity.

Cabinet Configuration Principles

l A single DBS3900 can be configured with a maximum of 12 remote radio units (RRUs). If there are more than 12 RRUs, they must be configured in more than one DBS3900. l A single advanced power module (APM) or transmission cabinet (TMC) can provide power

(44)

l A single APM can be configured with only one TMC and a maximum of two integrated battery backup systems with direct cooler (IBBS200Ds) or integrated battery backup systems with TEC (IBBS200Ts). TEC is short for thermoelectric cooling unit.

l A maximum of six power cables and twelve 2-wire fiber optic cables can be led out from a single APM.

l A single direct current distribution unit (DCDU) supplies power to a maximum of six RRUs. l The APM or TMC can be installed on the floor or stacked on the storage battery cabinet. l A backup battery cabinet (BBC) or IBBS200T can be stacked with a cabinet of the same

type or be stacked under a TMC.

l If an auxiliary cabinet such as a storage battery cabinet or transmission cabinet is required during an initial site deployment, the auxiliary cabinet is placed on the left, and the basic cabinet is placed on the right. If both the storage battery cabinet and the transmission cabinet are required, the storage battery cabinet is placed on the left of the basic cabinet and the transmission cabinet is placed onto the storage battery cabinet or on the left of the storage battery cabinet.

l Clearance must be reserved during an initial site deployment for future capacity expansion. In the capacity expansion scenario, the original cabinets are not relocated and new cabinets are added only to the right of the original cabinets unless they are required to be installed to the left of the original cabinets in exactly the reverse order of the original cabinets.

Requirements of Customer Equipment Specifications

Customer equipment to be installed in a Huawei cabinet must satisfy the following requirements: l Dimension requirements (as shown in Figure 2-10):

– The customer equipment must be 19-inch wide, which is the width of the standard equipment.

– The maximum depth of the customer equipment is 280 mm if the equipment supports natural ventilation or has air vents on the right and left; the maximum depth of the customer equipment is 250 mm if the equipment has air vents in the front and back. – A maximum cabling pace in front of the panel is 100 mm.

l Requirement for air vents:

– If the customer equipment has built-in fans, the fans must have air vents on the right and left or on the front and back so that wind blows from left to right or from front to back.

– If the customer equipment support natural ventilation, a minimum of 1 U slot must be reserved above and below the slot respectively for dissipation.

l Requirement for temperature

– In areas where the highest temperature is or is below 40°C, the customer must be able to function properly at –10°C temperature or even lower temperature and at 55°C or even higher temperature.

– In areas where the highest temperature is above 40°C, the customer must be able to function properly at –10°C temperature or even lower temperature and at 60°C or even higher temperature.
