Compliant with the IEEE 802.3bz standard, 2500BASE-T requires a Category 6 (Cat 6) or Category 5e (Cat 5e) 100-ohm UTP or STP (recommended) cable with a maximum distance of 100 meters (328 feet). When PoE power supply is used at the same time, a CAT6 STP cable is recommended, and both the port and cable should be properly shielded. Compliant with the IEEE 802.3ab standard, 1000BASE-T port requires a Cat 6 or Cat 5e 100-ohm UTP or STP (recommended) cable with a maximum distance of 100 meters (328 feet). When PoE power supply is used at the same time, a CAT6 STP cable is recommended, and both the port and cable should be properly shielded. The 2500BASE-T/1000BASE-T port requires four pairs of wires to be connected for data transmission. Figure 7-1 shows the four pairs of wires for the 2500BASE-T/1000BASE-T port. Figure 7-1 2500BASE-T/1000BASE-T Twisted Pair Connections The 100BASE-TX port can be connected using 100-ohm Category 5 (Cat 5) cables with a maximum distance of 100 meters (328 ft.).

Figure 7-2 100BASE-TX Twisted Pair Connection 7.2 Cabling Recommendations During installation, route cable bundles upward or downward along the sides of the rack depending on the actual situation in the equipment room. All cable connectors used for transit should be placed at the bottom of the cabinet rather than be exposed outside of the cabinet. Power cords are routed beside the cabinet, and top cabling or bottom cabling is adopted according to the actual situation in the equipment room, such as the positions of the DC power distribution box, AC socket, or lightning protection box. Requirements for Cable Bend Radius The bend radius of a fixed power cord, network cable, or flat cable should be over five times greater than their respective diameters. The bend radius of these cables that are often bent or plugged should be over seven times greater than their respective diameters. The bend radius of a fixed common coaxial cable should be over seven times greater than its diameter. The bend radius of the common coaxial cable that is often bent or plugged should be over 10 times greater than its diameter. The bend radius of a fixed high-speed cable (such as an SFP+ cable) should be over five times greater than its diameter. The bend radius of the fixed high-speed cable that is often bent or plugged should be over 10 times greater than its diameter. Precautions for Bundling up Cables Before cables are bundled, mark labels and stick the labels to cables wherever appropriate. Cables should be neatly and properly bundled in the rack without twisting or bending, as shown in Figure 7-3. 19 Hardware Installation and Reference GuideDebugging Figure 7-3 Bundling up Cables (1) Cables of different types (such as power cords, signal cables, and grounding cables) should be separated in cabling and bundling. Mixed bundling is disallowed. When they are close to each other, you are advised to adopt crossover cabling. In the case of parallel cabling, maintain a minimum distance of 30 mm (1.18 in.) between power cords and signal cables. The cable management brackets and cabling troughs inside and outside the cabinet should be smooth without sharp corners. The metal hole traversed by cables should have a smooth and fully rounding surface or an insulated lining. Use cable ties to bundle up cables properly. Do not connect two or more cable ties to bundle up cables. After bundling up cables with cable ties, cut off the remaining part. The cut should be smooth and trim, without sharp corners, as shown in Figure 7-4. Figure 7-4 Bundling up Cables (2) When cables need to be bent, you should first bundle them up, as shown in Figure 7-5. However, the buckle cannot be bundled within the bend area. Otherwise, considerable stress may be generated in cables, breaking cable cores. 20 Hardware Installation and Reference GuideMonitoring and Maintenance Figure 7-5 Bundling up Cables (3) Cables not to be assembled or remaining parts of cables should be folded and placed in a proper position of the rack or cable trough. The proper position refers to a position that does not affect device running or damage the device or cable. 220 V and 48 V power cords must not be bundled on the guide rails of moving parts. The power cords connecting moving parts such as grounding cables should be reserved with some access after being assembled to avoid suffering tension or stress. After the moving part is installed, the remaining cable part should not touch heat sources, sharp corners, or sharp edges. If heat sources cannot be avoided, high-temperature cables should be used. When screw threads are used to fasten cable terminals, the anchor or screw must be tightly fastened, as shown in Figure 7-6. Figure 7-6 Cable Fastening 1 Flat Washer 2 Nut 3 Spring Washer 4 Flat Washer Hard power cords should be fastened in the terminal connection area to prevent stress on terminal connection and cable. Do not use self-tapping screws to fasten terminals. 21 Hardware Installation and Reference GuideTroubleshooting Power cords of the same type and in the same cabling direction should be bundled up into cable bunches, with cables in cable bunches clean and straight.
