arraycabinet,localareanetwork(LAN)Switch,andkeyboard&video&mouse switcher (KVMS) are installed in the cabinet. This chapter describes the structure of the SG7000 cabinet as well as the structure and performance of the internal components.1.1Overview of Cabinet TheSG7000adoptstheN68-22standardcabinet.Thissectiondescribesthe appearance, structure, technical specifications and features of the cabinet.1.1.1Appearance of Cabinet The dimensions of the N68-22 cabinet are 2,200 mm (H) x 600 mm (W) x 800 mm (D). The usable internal space height is 46 U (1 U = 44.45 mm). The weight of an empty cabinet is about 130 kg. Figure 1-1 shows the appearance of the cabinet.

This is to facilitate the wiring and bundling of the internal cables.The N68-22 cabinet can be installed on the cement floor or in a room with an antistatic floor. The N800 series support is used when the cabinet is installed in a room with an antistatic floor.1.1.3N800 Supports and FittingsI. Introduction to Supports Thesupportisusedtoraisethecabinetandthusfacilitatecablingintheequipment room.Itismadeofweldedsteelsheets.Thecabinet,sliderailsandsupportare secured together by bolts to secure and support the cabinet.There are four types of N800 supports, three of which are height-adjustable and the last one has a fixed height.Figure 1-3 shows the appearance of the N800 series supports.

The adjustment is implemented through relative movement of the upper and lower supports.Type IV has a fixed height, and is mainly used in situations of extreme antistatic floor heights. The minimum floor height applicable for this type of support is 100 mm. II. Introduction to Bracket and Slide Assembly The bracket is used to support the floor around the cabinet, while the slide to connect the cabinet with the support. Figure 1-4 shows the appearance of the slide.(2)(1) (1) Hole for connecting the support(2) Hole for connecting the cabinet Figure 1-4 Appearance and dimensions of the slide III. Number of Supports and Number of Bracket and Slide Assemblies The number of supports can be calculated using the formula of 2 x N. That is, each cabinet independently uses one set of supports (2 supports), and a row of cabinets (N cabinets) uses 2 x N supports.Each cabinet uses one set of bracket and slide assembly, which is delivered with the supports.Eachsetofbracketandslideassemblycomprisestwoslides,twolateral brackets, two bracket fixing pieces, one front bracket, and one rear bracket.Hardware Description Manual U-SYS SG7000 Signaling GatewayChapter 1Cabinets Huawei Technologies Proprietary 1-5 Each cabinet needs two bracket fixing pieces, one front bracket, and one rear bracket. Each row of cabinet also uses two lateral brackets. If only one cabinet forms a row, two lateral brackets are also needed.1.1.4Technical Specifications and Features of Cabinet Table 1-2 lists the specifications and features of the N68-22 cabinet.Table 1-2 Technical specifications and features of the N68-22 cabinet Design standards The cabinet complies with International Electrotechnical Commission (IEC)297standardsandadoptsthemodulardesigntofacilitate capacity expansion and maintenance.Outer dimensions2,200 mm (H) x 600 mm (W) x 800 mm (D) Capacity The usable internal space height is 46 U.

Its internal components include the BAM, disk array cabinet (optional), KVMS, LAN Switch and frames. The basic cabinet provides such functions as basic service processing, external interfaces (FE, clock, E1, and so on) of the SG7000, and communication between the foreground and background.The fixed configuration of the basic cabinet includes one BAM, two LAN Switches, one KVMS, one or two frames, and one direct current (DC) power distribution box. You can also configure another BAM to form the dual-system mode. In this case, a disk array cabinet is also needed. The weight of a basic cabinet with full configuration is about 400 kg.Figure 1-5 shows the full configuration of a dual-system basic cabinet.Hardware Description Manual U-SYS SG7000 Signaling GatewayChapter 1Cabinets Huawei Technologies Proprietary 1-7 KVMSLAN Switch 0Dummy panelDC power distribution boxLAN Switch 1BAM 0BAM 1LAN Switch cabling f rameLAN Switch cabling f rameAir def lectorService f rame 1Service f rame 0Air def lectorDummy panelAir def lectorDummy panelDisk arraycabinet Figure 1-5 Configuration of the basic cabinet1.2.2Extended Cabinet Theextendedcabinetprovidesthebasicserviceprocessingfunctionandexternal interfaces.Onlyframesareconfiguredintheextendedcabinet.Thenumberofthe Hardware Description Manual U-SYS SG7000 Signaling GatewayChapter 1Cabinets Huawei Technologies Proprietary 1-8 frames configured depends on the system capacity.

This section describes the specifications and features of these components.1.3.1BAM Note:Themanufacturer,model,andhardwareconfigurationoftheBAMservermaydiffer from what are described here. In that case, the delivery prevails. The description of this document is for reference only. The BAM is a server of the operation and maintenance (O&M) system of the SG7000. It acts as a bridge between the SG7000 and workstations. The BAM forwards the O&M commands of workstations (local/remote) to the host and redirects the responses of the host to related O&M workstations. In addition, it stores and forwards alarm information and service statistics data. You can install one BAM or two as you like. The SG7000 adopts IBM X343 server as the BAM server, which is fixedly configured in the basic cabinet.I. Appearance of IBM X343 Figure 1-7 is the front view the BAM server with the case.

Function Usually, the air deflector is above or under the service frame. It changes the direction of air slowly and separates the heat dissipation channel. This forms the ventilation mode in which air comes in from the front, goes out from the rear. It also decreases the loss generated by the compression of air. Figure 1-22 shows the heat dissipation channel inside the cabinet after the air deflector is installed.
