Installation Steps

Caution!

Correctly connecting the switch ground wire is crucial to the lightning protection andelectromagnetic susceptibility (EMS) of a switch.

The power input end of the switch is connected to a noise filter, whose central groundis directly connected to the chassis, forming the chassis ground (commonly known asPGND). This chassis ground must be securely connected to the earth ground so that thefaradism and leakage electricity can be safely released to the ground, enhancing the EMScapability of the switch.

The correct grounding methods are as below:

l If a grounding strip is available on the installation site, attach one end of theyellow/green ground wire of the switch to the grounding screw on the grounding stripand fasten the captive nut, see Figure 3-28. (Note that the fire main and lightning rodof a building are not suitable for grounding the switch. The ground wire of the switchshould be connected to the grounding device for the equipment room).

Figure 3-28 Grounding the Switch through a Grounding Strip

1. Protective groundingterminal of the switch

2. Grounding bar in theequipment room

l When there is no grounding strip but earth near the equipment room that allows agrounding body to be buried, hammer an angle iron/steel pipe longer than 0.5 m into

3-43



the earth, see Figure 3-29. Weld the yellow-green ground wire of the switch onto theangle iron/steel pipe, and process the joint against erosion.

Figure 3-29 Grounding the Switch by Burying the Grounding Body into the Earth

2. Ground 3. Angle steel or steeltube

l For an AC-powered switch, if none of the above two conditions is available, groundit through the PE wire of the AC power supply, see Figure 3-30. In this case, makesure this PE wire is well connected to the ground at the power distribution room or ACtransformer side.

3-44

3.2.5 Fiber

OverviewOptical fiber is a communication medium that uses a bundle of thin glass rods to transmitthe modulated light. There are two fiber types: single mode fiber and multimode fiber. Theuser may select one according to the particular situation.l Multimode fiber: transmitting signals by using the multiple modes of light; used for

short-distance transmission; usually named as the 8.3/125 um fiber.

3-48



l single mode fiber: transmitting signals by using the single mode of light; used forlong-distance transmission; usually named as the 50/125 um or 62.5/125 um fiber.

Each fiber cable is composed of five parts: fiber core, cladding layer, buffer layer,strengthening layer and outer jacket. Fiber core is the optical transmission componentlocated at the cable core. It is usually made of silicon or glass. The chemical compositionsof fiber core are partially different from those of the cladding layer, so that the lightentering at a specified angle would be reflected continuously by fiber core and claddinglayer. Therefore, light remains in the fiber core during the whole transmission process.

The Physical cross-sectional area of a fiber cable is shown in Figure 3-34. The figureshows the location of the five components.

Figure 3-34 Fiber Cable Cross-sectional Area

Laser Usage Safety

The ZXR10 2900E series Ethernet switch belongs to type I laser equipment.

If an optical interface of the ZXR10 2900E series switch is in working state, do not look atthe interface directly. The beam emitted by the fiber has very great energy, and looking atit directly will damage your retina.

Note:

It will hurt your eyes to have eye contact with laser beams of optical fiber.

Fiber Installation

Each optical interface of the ZXR10 2900E can be connected to an SFP module. Forthe supported rates, refer to the model description. Two types of fibers are available:single-mode fiber andmulti-mode fiber. User can configure the fiber according to the actualapplication. Table 3-38 shows 6 types of fiber.

As for fiber out of the cabinet, make sure to protect the fiber against any damages withplastic corrugated sleeve. The fiber within the protect sleeve must not be wound up andthe corners must be radian. The labels at two ends of the fiber must be clear. The meaningof the label must correctly reflect corresponding serial numbers and relationship betweencabinets and between rows.

4.3 Cable LayingThe ZXR10 2900E cables consist of group wire, power cable, serial console cable, networkcable and fiber.

4.3.1 Installation Specifications

Installation Specifications for Power Cables and Grounding Cables

l Layout Principles

Power cables are straight and with smooth arcs at turning sections.

No connecting or wielding point exists in the middle of a power cable.

The extra part of a cable is cut off, instead of being coiled.

The bending radius at a turning section of a power cable is 5 times greater than thecable diameter.

Power cables are laid properly, without crossing, coiling, or twisting.

Before a signal cable is installed, a connectivity test must be carried out. Both endsof the signal cable are attached with marks or engineering tags.

Power cables and signaling cables are separated by at least 300mm. Do not bindthem together.

For an optical fiber, the turning radius is not less than 4cm.

l Binding Principles

Power cables and signal cables are bound separately.

The binding interval of power cables is 200mm.

Do not let turning components (such as a door) press or drag the cables, and bindingis not allowed at turning sections.

Wire fasteners are facing the same direction. Cut the excessive part after binding,and the cutting is even.

l Overhead Cabling Principle

In overhead cabling mode, the cables are routed out of the top of the DC powerdistribution cabinet to the top of each device cabinet through a cable try.

l Raised-floor Cabling Principle

In raised-floor cabling mode, the cables are routed out of the bottom of the DC powerdistribution cabinet to the bottom of each device cabinet through the anti-static floor.

Installation Steps

1. Plan the cabling path.

When planning the cabling path, take future expansion into consideration, so that thesystem can still operate properly after expansion.

2. Install protective grounding cables and power cables.

Before installing power cables, ensure that the protective grounding cables of theswitch contact the earth well. For details of how to install grounding cables and powercables, refer to Section 3.2 "Cables".

3. Install signal cables.l Install configuration cables.l Lay network cables.l Lay optical fibers.

For details of how to install signal cables, refer to Section 3.2 "Cables".

4.3.2 Power-on ProcedureCheck the lab environment and hardware installation before power-on ZXR10 2900E.

1. To make sure that the switch operates normally and has a normal service life, thecertain temperature and humidity of equipment room should be maintained.l If the humidity of the equipment room has been too high for a long time,

leakage will happen or the insulating function will not good. Sometimes materialmechanical feature will change or metal components will rust. If the relativehumidity is too low, the insulating pad will shrink and cause loose of fastenedscrew. At the same time, static will happen which endangers the circuit of switch.

l The harm of high temperature is larger. The longtime high temperature will speedthe aging process of insulating material, which reduces the reliability of switch andaffects the life of the switch.

2. Check whether the power cable and other cables are connected correctly and reliably.3. Check other hardware.

a. Check whether devices are labeled completely, correctly and clearly.

b. Check whether the switch is firmly installed in a 19-inch standard rack or ondesktop.

c. Check whether rack has a good contact and whether the earthing resistancemeetstechnical requirements.

Caution!l Make sure that the arrester is well grounded before using the lightning arrester for

power.l After inserting AC power cord plug of switch into the socket of lightning arrester, if the

green LED is on and the red LED does not alarm, it means that the lightning arresterof power is running and the function of lightning protection has taken effect.

l When the arrester is installed, users should install and debug according to theinstruction to arrester and comply with the engineering technical requirementsin GB50343 Building Electronic Information System lightning- proof TechnologySpecification and YD/T5098 Telecommunication Bureaus (Stations) LightingOvervoltage Protection Engineering Design Specification, which ensures reasonablegrounding, bonding and isoelectric connection.

l The security of lightning- proof system should be checked regularly such as the checkbefore and after each thunderstorm season including if the lightning- proof moduleof device is damaged or performance is not good, if the bonding performance ofconnection is not good. If these conditions above happen, please change or handlein time.

4.4.2 Installation of Lightning Arrester for Network Port

Note:

Lightning arrester for network port is specially designed for the Ethernet port of 10/100Melectrical interface (RJ-45 connector is used in this case).

Caution!

Lightning arrester for network port will not be provided along with the switch, and youshould purchase it if needed.

If an outdoor network cable should be led to the switch, serially connect the lightningarrester for network port before you plug this cable into the interface on the switch, incase of the possibility that the switch may be damaged due to lightning strike.
