Product Description

The SC 4812ET BTS consists of an RF Cabinet that is an outdoor, weatherized version of the SC 4812T. The RF cabinet is powered by 27 VDC and each cabinet has the capability to support up to 4 carriers (at 3 sector) or 2 carriers (at 6 sector). An optional outdoor, weatherized Power Cabinet that provides AC/DC rectified power and battery back–up is also available. An air to air heat exchanger is used for conditioning each cabinet, except in the LPA area of the RF cabinet which uses blower fans to draw outside air over the LPAs.

The SC 4812T utilizes a new RF “Trunking” technique that provides shared power between sectors and increased RF output capability. The SC 4812ET will support additional expansion cabinets to add more carriers. Duplexer/Directional couplers will be standard equipment for the SC 4812ET BTS.

The RF Cabinet houses the fan modules, Combined CDMA Channel Processor shelf (C–CCP), Linear Power Amplifiers (LPA) modules, LPA trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive Filter/Directional Couplers (DRDC) and a DC Power distribution assembly. The Power Cabinet (PC) provides +27 V DC distribution and battery backup for the SC 4812ET. The Power Cabinet houses batteries, battery heaters, rectifiers, an AC Load Center (ACLC), a power distribution assembly, and two duplexed GFCI convenience outlets.

Overview

The major components which make up the Motorola SC 4812ET RF Cabinet (see Figure 1-2) and Power Cabinet (see Figure 1-7) system are illustrated in this section.

CAUTION

A service tent [reference: Pelsue Cabinet Mounted Service Tent; Pelsue (800–525–8460) P/N CM564866M] must be in place prior to opening the main doors of the SC 4812ET RF or Power Cabinet during times of inclement weather (rain, snow, sleet, or hail). This will prevent moisture from being drawn into the electronics by internal fans and damaging the equipment.

A service tent [reference: Pelsue Cabinet Mounted Service Tent; Pelsue (800–525–8460) P/N CM564866M] with a heater is required to service the SC 4812ET RF Cabinet when temperatures are below –10 degrees C (14 degrees F). Temperatures inside the tent should be above 0 degrees C (32 degrees F) prior to opening the main cabinet door. This will prevent a rapid temperature change to the electronics which could result in site outage.

External Blower Assembly (EBA)

The External Blower Assembly (see Figure 1-5) is a modular unit that provides cooling to the LPA’s, two blowers are used in the RF Cabinet.

Figure 1-5: External Blower Assembly (EBA)

CAUTION

The EBA contains two blowers and provides cooling that is VITAL to prevent service outage and possible damage to the LPAs. Since the SC 4812ET can continue to operate normally with one functional blower in the EBA, the EBA should not be removed until the replacement EBA is onsite. Then, the EBA is replaced as a unit while the RF cabinet is running. The replacement must be done within 3 minutes to prevent damage to the LPAs. Refer to the SC 4812ET FRU Guide for details regarding FRU replacement.
