Design description of cabling system
I. System Overview
Cabling System, also known as structured cabling system is a modular, highly flexible, intelligent building cabling networks, voice is used in building and construction group, data, image signal transmission integrated wiring system.
II. design range
The room cabling system mainly consists of two parts:
A. Auxiliary space Cabling System
B. Data computer room area Cabling System
III. System Design
A. Auxiliary space Cabling System Design
Data and Voice Point Cabling System integrates the speech signal, digital signal in a standard wiring systems through standard designing, this system is an open network platform, can be formed a separate sub-systems when necessary. It can make resource sharing, information database management, e-mail, personal database, report processing, financial management, conference calls, video conferencing, etc.
Set two data point and two voice point at each seat in Noc room meeting room Noc manager office and monitoring center. Point installed above the table's.Set a data point and a voice point in server room power room entrance Room and telecom room. Point installed on the wall.
The system total set of 140 data points and 128 voice points. The horizontal cable using Cat6 4P UTP to achieve 100Mb/s bandwidth to desktop. cable by laying to cable tray between telecom room cabine.using 48-port patch installation.
The system all cables fire rating is required to achieve CMR rating. Outlet socket uses RJ45, Cat.6, concealed.
The principle of pipe laying： 1~2 Cat.6 UTP 4p whit one Ø20 pipe.
3~4 Cat.6 UTP 4p whit one Ø25 pipe.
B. Data computer room area Cabling System Design
1. Cabing system constitute
1) The data center cabling system in accordance with tia_942 of tier 3 standards for design.
2) Integrated wiring system uses a star topology, divided into the main distribution area (MDA), the horizontal distribution area (HDA), and equipment distribution area (EDA).
3) The data computer room total set of 136 cabinet. The first cabinet of each row is the horizontal distribution area (HDA), HDA jurisdiction of seven cabinet of the row.
4) The data computer room cable using pre-connection cable.
5) The data computer room cable using Category 6 cable , within a short distance meet 10-Gigabit Ethernet. panels are using 48-port/1u 6 utp patch panels.
2. Wiring District IV program description
1) MDA, is the core of the data center management area:
Using 24 core OM3 multimode fiber cross-connect (dual route backup) the main distribution area (MDA) and horizontal distribution area (HDA).
2) HDA, the data management area is the horizontal center:
Using 48 core Category 6 cable connect the horizontal distribution area (HDA) and equipment distribution area (EDA) . Within HDA cabinet Using two 6 utp patch panels cross-connect , one patch panels connect to patch panels in the EDA cabinet, and the other one connect switch in the HDA cabinet. Set 48-port lc-lc Fiber optic patch panels in the HDA cabinet , equipment in the EDA cabinet can be connected to this patch on demand.
3) EDA, equipment for storage area:
Equipment distribution area (EDA) Each cabinet set aside in accordance with 15 servers, install a 48-port 6 utp patch panels. using the 1m 3m length jumper, the number of 1:4 configuration. 作者: 穿着拖鞋闯澡堂 时间: 2014-7-11 00:57
