Connecting Interface Cables 67 Connecting Interface Cables Connecting Console Cable Introduction Console cable is an 8-core shielded cable. At one end of the cable is a crimped RJ-45 connector that is to be plugged into the console port of the switch. At the other end of the cable are a DB-9 (female) connector and a DB-25 (female) connector. You can plug either of them into the 25-pin (male) or 9-pin (male) serial port on the console terminal as needed. The following figure illustrates the console cable.
CHAPTER 4: SWITCH INSTALLATION n The PC serial port is not hot-swappable, so you are not allowed to insert or remove the console cable into or from the PC serial port. When connecting the console cable, first connect the DB9/DB25 end to the PC serial port and then the RJ45 end to the console port of the switch. And removing the console cable is just in inverse order. When removing the console cable, first remove the RJ-45 end and then the DB9/DB25 end.

CHAPTER 4: SWITCH INSTALLATION Figure 51 LC connector Connecting fiber Step 1: Plug one end of the fiber into the SFP optical module of the Switch 8800 Family. Step 2: Connect the other end of the fiber into the corresponding device. c CAUTION: When the optical interface has not been connected with a fiber connector or its dust-proof mesh is open, there might be some invisible radiation emitted from the optical interface. So do not look into the optical interface directly.
Cable Management 71 Figure 52 Cable bundling example I Intertwined Bent ■ The bending radius of cable body cannot be less than twice of the cable diameter. The bending radius of the cable cannot be less than 5 times of its diameter at the place where it is led out of the connector; ■ Different cables (power cord, signal cable, PGND wire, etc.) should be cabled and bundled separately rather than together in the cabinet. If they are close to each other, you can cable them in cross-shape.
CHAPTER 4: SWITCH INSTALLATION ■ Bundle the cables wherever cable bending cannot be avoided. However, the cable ties cannot be placed inside the bending area in case of the likelihood of cable core break due to excessive stress. See the following figure. Figure 54 Cable bundling example III ■ The spare cables or excessive cable parts should be folded and bundled and placed at a right place in the cabinet or on the cabling channel.
Verifying the Installation 73 ■ When using a hard power cord, fix it near its terminal so as to free the terminal and the cable from stress; ■ Do not use tapping screws to fasten the connecting terminals; ■ The power cords of the same type and in the same direction should be bundled together and kept neatly and straight; The following table lists the requirements in the bundling with cable ties.

6 SWITCH MONITORING AND MAINTENANCE Monitoring the Switch Although the Switch 8800 Family has undergone a comprehensive factory test before delivery, an improper installation may cause problems. This chapter describes how to troubleshoot the Switch 8800 Family. Troubleshooting Console Terminal If the system running properly, when you power on the switch, you will see the boot information on the console terminal.
CHAPTER 6: SWITCH MONITORING AND MAINTENANCE The following PSU faults may appear on the switch. Follow the instructions provided to resolve the problem. Display Power Command Indicates the PSU is Not in Position The Input LED (green) and Output LED (green) stay ON, but the display power command shows that the PSU is not in position (but the other PSU operates normally). This problem is likely caused by a poor connection (badly seated) between the PSU and the backplane.
Hardware Maintenance Troubleshooting I/O Module ■ The fans are working normally. ■ The rotation of the fans has not been blocked. ■ The blank filler panels have been inserted into the I/O module slots. 81 The Switch 8800 Family provides I/O moduleX LEDs on the fabric so that you can check the state of these I/O modules. Table 77 I/O Module LEDs Indicator State description RUN ON indicates an I/O module failure. OFF indicates that the I/O module has failed or it is not in position at all.
