IDC core network equipment, especially the internal network core equipment, will be more interconnected with TOR, so there will be more optical fibers. The optical fiber layout of the core network equipment must be neat and not interspersed. The neat and beautiful wiring in the cabinet is one of the key points in the network equipment wiring specification.
The optical fiber is laid vertically from the left or right side of the device, and the place where it is laid cannot block the air inlet and outlet of the network device. The optical fibers are bound with Velcro straps at intervals (note: white fixing straps cannot be used), but they cannot be tied too tightly and the bending degree cannot be too large. They are usually between 100 degrees and 130 degrees, mostly about 110 degrees (the same below) ), to be able to relax freely. Stick the label, try not to block the label after inserting it into the device port, and leave a certain length of space to facilitate the removal and insertion of the optical fiber.
The internal network access switch is located at the top of the rack. The 40G MPO fiber of the internal network TOR switch is connected to the internal network core, and the 10G-AOC cable is connected to the server. The 1G or 10G port of the ILO switch is connected to the core of the management network, and the Gigabit port is connected to the server. The two cabinets in the computer room share an intranet TOR and an ILO access switch, and roughly 18 servers are placed in each cabinet.
The cables laid out by the internal network access switch are organized by a cable organizer. On the cable organizer, each 4 network cables are bound with a cable tie. Each network cable is marked with a label, and the other end is placed on the tray in the rack. The lowering length of the optical fiber does not need to be too long, and the bending degree cannot be too large. The optical fibers that are labeled and connected to different cores should be distinguished by labels of different colors as much as possible.
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 neatly arranged separately and tied with cable ties at intervals to keep the appearance beautiful.
Inside the cabinet (ordinary server cabinet) there are mainly intranet AOC cables and ILO management network cables, as well as power cables. Therefore, there will be more cables in a single cabinet, and each type of cable needs to be bundled and laid inside the cabinet. Different cables are distinguished by cables of different colors, such as internal network cable: blue, ILO cable: gray, and power cable: black. The length of the reserved cable should not be too long. It can be from one side of the PDU to the other side of the PDU, and the reserved length of the cable will affect the cable management.
