3.9 Connecting Interface Cables

3.9.1 Cable Routing Recommendations

Interface cables and power cables should be routed separately. You can bind long cables with cable ties. For specific binding requirements, refer to Appendix A “Cable Binding”.

I. Workbench-mounted switch

All interface cables are routed to the left side (the cable management bracket) of the chassis, and power cables are routed to the front of the chassis.

II. Rack-Mounted switch

l The interface cables are bound on the cable management bracket on the left side of the chassis and are routed up or down to pass through the chassis top or the raised floor, depending on the available equipment room condition (that is, signal cables are routed into the chassis either from the cabling racks on the chassis top or from the cabling trough under the floor).

l All digital signal cable connectors should be put at the bottom of the cabinet. Do not put them outside the cabinet.

l Power cables run along the left-front of the chassis and out of the chassis either from the top or the raised floor, depending on the equipment room conditions (PDF, lightning protection box, and terminal block, etc.) in the equipment room.

Caution:

l Do not bind cables at the air exhaust vents of the switch to prevent premature cable aging.

l Fix cables as near the device as possible. The cables between the fixing point and device interfaces must be bound loosely.

l To identify cables, you can stick labels on them. For more information, refer to Appendix B “Engineering Labels for Cables”.

II. Connecting the console cable

Take the following steps to connect the console cable, when configuring the switch on the terminal.

1) Plug the DB-9 female connector of the console cable into the serial port of the PC/terminal where the switch is to be configured.

2) Connect the RJ-45 connector of the console cable to the console port of the switch.

Figure 3-22 Connect the console cable

& Note:

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 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 end.

3.9.3 Connecting the AUX Cable

You need an AUX cable when configuring the S9500 series with the remote modem dial-up approach.

I. Introduction

The AUX cable is an 8-core shielded cable. At one end of the cable is an RS-232-compliant RJ-45 connector that can be plugged into the AUX port of the switch. At the other end is DB-9 (male) connector. You can plug it into the DB-9 (female) port of the modem. The AUX cable is the same as the console cable. For details, refer to Figure 3-21 and Table 3-3.

II. Connecting AUX cable

1) Plug the RJ-45 connector of the AUX cable into the AUX port of the switch.

2) Plug the DB-9 (male) connector at the other end into the serial port of the modem.

3.9.4 Connecting Network Cables

I. Introduction to RJ-45 connector

The 10/100/1000Base-T ports of the S9500 series support MDI/MDI-X auto-sensing. They are connected to category-5 shielded cables or above that are equipped with RJ-45 connectors.

Figure 3-23 RJ-45 connector

3.9.5 Connecting Fiber

I. Installing fiber management tray (optional)

& Note:

The installation method described below is based on an N68 cabinet. The installation procedure is only for your reference if you use a non-N68 cabinet.

A fiber management tray (FMT) is installed in a cabinet for winding redundant fibers between the S9500 and other devices.

1) Preparations

The installation prerequisites are as follows:

l The cabinet is fixed well.

l The device has been installed completely.

The installation involves the following materials:

l FMT

l M5×10 self-tapping screws (two screws for one FMT)

2) Installation Procedure

To install the fiber management tray, proceed as shown in Figure 3-24.

l Align the fiber management tray and the installation holes on the column of the cabinet.

l Use a Phillips screwdriver to fix each fiber management tray with two M5×10 self-tapping screws.

Figure 3-24 Install FMTs

II. Introduction to fiber connector

& Note:

l When selecting a fiber network facility, make sure that the type of the connector and the fiber match the adopted optical port.

l Before connecting the fiber, make sure that the receive-end optical power does not exceed the optical module’s upper threshold of receiving optical power. Excessive receiving optical power is very likely to burn the optical module.

l All the megabit and gigabit optical modules available on the S9500 series are SFP modules and all interfaces on SFP modules adopt LC connectors.

Fiber connectors are indispensable passive components in an optical fiber communication system. They allow the removable connection between optical channels, which makes the optical system debugging and maintenance more convenient and the transit dispatching of the system more flexible. Among various fiber connectors, only the LC connector is introduced here.

Figure 3-25 LC connector

III. Precautions

l Be sure to install the dust cover if the optical port is not connected to a fiber connector.

l Some invisible rays may be emitted from the optical port if the optical port is not connected to a fiber connector or the dust cover is removed. Therefore, never stare at the optical port directly.

l Fiber connectors must be protected under safe and reliable outer packing, and be fitted with dust caps. Fiber connectors must be installed with dust caps when they are not in use. Take care not to scratch their end face. Replace the dust cap if it loose or polluted.

l Before connecting a fiber, use dustfree paper and absolute alcohol to clean the end face of the fiber connector. You can brush the end face only in one direction. You also need to brush the end face of the other fiber connector.

l Never bend or curve a fiber when connecting it. After a fiber is installed well, the bend radius must be not less than 40 mm (the minimum dynamic bend radius is 20 D, and the minimum static bend radius is 10 D. D indicates the outer diameter of fiber jackets).

l If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted surface (the filleting radius must be not less than 2 mm). When passing through a metallic board hole or bending along the acute side of mechanical parts, the fiber must wear jackets or cushions.

l Insert and remove a plug with care. Never exert a fierce force to the fiber or plug; otherwise the plug may be damaged or the fiber may be broken. Never pull, press or extrude the fiber fiercely. For the allowed maximum tensile load and crush load, refer to Table 3-4.

Table 3-4 Allowed maximum tensile force and crush load

Period of force	Tensile load (N)	Crush load (N/100 mm)
Short period	150	500
Long term	80	100

IV. Connection procedure

1) Connect one end of the fiber to the SFP module of the S9500 series.

2) Connect the other end of the fiber to the peer device.
