Organizing the wiring is an important part of the equipment room. Why should the wiring be arranged? Fortunately, it is necessary to correspond to the ports one by one during later maintenance. This is the purpose of the neat wiring. Wire tips and wiring specifications.
Tools: cable management rack, cable management clip, bridge holder, cable tie, line card, crystal head, adhesive tape, label paper and line processing equipment.
First, wiring skills
1. Use a cable tray. The cabinet wiring rack is a 1U or 1SU sheet metal part with N teeth. The length of the teeth is different, depending on the size of the network equipment and the turning radius of the cable.
2. Use a wire bridge. The wire bridge is a small bridge-shaped structure with a radius protruding from the cabinet. Generally, the cable bridge will appear in the following places: the compartment partition of the cabinet, the column, the square hole strips where the equipment panel is installed, etc.
3. Use a winding reel. This is generally used for optical fiber finishing of communication equipment.
4, flexible use of (travel) bobbin. Inlet (travel) spool refers to the place where the cabling on the subdivision bulkhead is required when cabling is required in different subdivisions. Generally, the incoming (traveling) spool appears between two compartments that need to be isolated from each other, such as between the equipment compartment and the battery compartment.
5. Use cable ties and labels. Cable ties are easy to use and flexible, while labels make it easy to identify after routing, reducing maintenance difficulties.

Second, the wiring specifications in the computer room
1. Core equipment wiring specifications
IDC core network equipment, especially intranet core equipment, will be more interconnected with TOR, so there will be more fiber. The optical fibers of core network equipment must be arranged neatly, and they cannot be interspersed horizontally and vertically. The beautiful wiring in the cabinet is one of the key points in the network equipment wiring specifications.
The optical fibers are routed vertically from the left or right side of the device. Do not block the air inlets and outlets of network devices. The optical fibers are bundled with Velcro bands at intervals (Note: the white bands cannot be fixed), but they cannot be bundled too tightly and not too bent, between 100 and 130 degrees, usually about 110 degrees (the same below ), To be able to loosen, stick the label, and try not to block the label after inserting it into the device port, there must be a certain length of space to facilitate the insertion and removal of optical fibers.

2. Intranet access wiring specifications
The internal network access switch is located at the top of the rack. The 40G MPO fiber of the internal TOR switch is connected to the internal network core, and the 10G-AOC cable is connected to the server. The ILO switch 1G or 10G port is connected to the core of the management network, and the gigabit port is connected to the server. One of the two cabinets in the equipment room shares one intranet TOR and one ILO access switch. Approximately 18 servers are placed in each cabinet.
The cables deployed in the intranet access switch are organized by a cable manager. Each 4 network cables on the cable manager are bundled with cable ties. Each network cable is labeled with a label and the other end is placed in a tray position in the rack. . The length of the optical fiber does not need to be too long, and the degree of bending cannot be too large. The optical fibers with labels attached and connected to different cores should be distinguished by labels with different colors as much as possible.
3.Wiring specifications in the bridge
The interconnection cables between network devices in the equipment room need to be routed through the bridge (except in a single cabinet). The optical fibers and network cables in the bridge are laid out neatly and bundled with cable ties at a certain distance to maintain beauty.

4.Wiring specifications in the cabinet
In the cabinet (common server cabinet), there are mainly internal network AOC cables and ILO management network cable cables, and there are also power cable cables. Therefore, there will be a large number of cables in a single cabinet, and each type of cable needs to be laid inside the cabinet.
Different cables are distinguished by different colored cables, such as the internal network cable: blue, ILO cable: gray, power cable: black, and the reserved cable length should not be too long. It can be from one side of the PDU to the other. Reserve too long cables will affect the cable management.
