Quidway R2600/3600 Series Modular Routers	Installation Preparations

Chapter 3 Installation Preparations

3.1 Safety Recommendations

Routers play the key role in data communications network. Please pay attention to the following:

Warning: It indicates that this operation may seriously damage the router or endanger the operator. Please follow the operation procedures for sake of safety.

Caution: It indicates that during the installation and usage of the router, the operation needs attention. Though this operation will not do any damage to the router or endanger the operator, it may affect the normal operation of the router.

Please follow the following safety recommendations during the installation and use of the router:

zKeep the router away from water or any wet place.

zKeep the router away from any heat source.

zMake sure that the router is normally grounded.

zWear ESD-preventive wrist strap during installation.

zDo not hot unplug the modules of the router.

zDo not hot unplug any cable.

zAlways use UPS.

3.2Installation Conditions

R2600/3600 series must be used indoors. To ensure the normal operation and prolong their service life, the following requirements for installation site must be met.

3.2.1 Temperature and Humidity Requirements

Certain requirements on temperature and humidity in the equipment room shall be met. If the relative humidity is too high, the insulation materials in it will deteriorate easily or even lead to electric leakage. Sometimes this will result in change to the mechanical performance of the materials and rusting of the metal components. If the relative humidity is too low, the fastening screw will become loosen due to shrinkage of the isolation spacer. In an environment with dry climate, the static electricity may be produced, putting the CMOS of the router to risk. High temperature is of the greatest risk: for it will significantly degrade the router’s reliability, speed up the aging process of the insulating materials, and shorten the service life of the router. The requirements on the temperature and humidity for R2600/3600 series are shown in Table 3-1:

3-1

Installation Manual							Chapter 3
Quidway R2600/3600 Series Modular Routers						Installation Preparations
Table 3-1 Humidity requirement in the equipment room
		Temperature				Relative humidity
	Normal operating condition		Safety operating		Normal operating condition		Safety operating
			condition				condition
	15OC to 30OC		0OCto 45OC		40% to 65%		10% to 90%

Note:

1)The values of environmental temperature and humidity in the equipment room are measured at 1.5m high and 0.4m away from the front of the router rack when there is no protective board installed in front and at the back of the rack.

2)Safety operating condition refers to the continuous operation for less than 48 hours or the accumulative annual operation time less than 15 days.

3)The extreme environment refers to the likely environmental temperature and humidity when the air conditioning system in the equipment room fails (the normal operating condition should be recovered

within five hours for each failure).

3.2.2 Cleanness Requirements

Dust undermines the normal operation of R2600/3600 series. Dust dropping on the equipment can cause electrostatic adsorption, which degrades the contact performance of the metal connection parts or connectors. This happens more frequently when the indoor relative humidity is low, which will not only shorten the router’s service life, but also cause communication failure.

The recommended specification on dust content and particle diameter in the equipment room is shown in Table 3-2:

Table 3-2 Specification on dust content in equipment room

Maxim diameter ( m)	Max. intensity (particles per cubic meter)
0.5	1.4 x 107
1	7 x 105
3	2.4 x 105
5	1.3 x 105

The routers also have rigorous demand on the content of salts, acids and sulfides in the air. These harmful gases will speed up the metal rusting and the aging processes of certain parts. The equipment room should be protected from the invasion of harmful gases such as SO2, H2S, NO2, NH3 and Cl2, the value limits of which are shown in Table 3-3:

3-2

Installation Manual			Chapter 3
Quidway R2600/3600 Series Modular Routers			Installation Preparations
Table 3-3 Value limits for harmful gas contents in equipment room
	Gas	Average (mg/m3)	Max. (mg/m3)
	SO2	0.2	1.5
	H2S	0	0.03
	NO2	0.04	0.15
	NH3	0.05	0.15
	Cl2	0.01	0.3

3.2.3 ESD-Preventive Requirements

Although many antistatic considerations have been given to R2600/3600 series, damage to the router’s circuit or even the whole equipment may still happen when the static electricity exceeds the tolerance threshold.

In the communication network to which the routers are connected, static induction mainly comes from:

zExternal electric fields such as outdoor high voltage power line or thunder.

zInternal environment like flooring materials or the whole equipment structure.

Thus, the following should be considered to safeguard the equipment against the static damage:

zMake sure that the equipment and the floor are well grounded.

zMake sure that dust-proof measures are taken.

zMaintain an appropriate humidity and temperature.

zWear an ESD-preventive wrist strap and uniform when contacting the circuit board.

zPlace the uninstalled circuit board on the antistatic workbench, with its face upward, or put it into the electromagnetic shield bag.

zWhen observing or removing the uninstalled circuit board, please touch the edge of the circuit board, and avoid contacting the devices on it.

3.2.4Anti-interference Requirements

The interference sources, no matter where they come from, affect the routers with capacitance coupling, inductance coupling, radiation of electromagnetic wave, common impedance (including the grounding system) or conducting line (power line, signal line and transmission line etc.).

So the following should be considered:

zTake effective measures to prevent the power system from being interfered with by the power grid system.

zSeparate the working ground of the router from the grounding device of the power supply equipment or anti-lightning grounding device as far as possible.

zKeep the router far away from the radio launcher, radar launcher, and highfrequency devices working in high currents.

zUse electromagnetic shielding when necessary.

3.2.5Lightning Protection Requirements

Although many measures have been taken to protect R2600/3600 series from lightning, if the lightning intensity exceeds a certain range, damage to the router may still happen. To protect the router from lightning better, the following should be considered:

3-3

Installation Manual	Chapter 3
Quidway R2600/3600 Series Modular Routers	Installation Preparations

zEnsure the shell of the chassis is well grounded through the ground wire.

zEnsure the neutral point of the socket of AC power supply is well grounded.

zTo enhance the lightning protection capability of the power supply, a lightning arrester could be installed at the input end of the power supply.

zAs for the signal line led out to the outdoor from the function modules of R2600/3600 series, such as ISDN line, telephone line, E1 line, etc, a special lightning arrester should be installed at the input end of the signal line to enhance the lightning protection capability.

3.2.6Workbench Requirements

No matter whether you are to install the router in the cabinet or directly place it on the workbench, it is necessary to ensure that:

zThere is spacing reserved at the air inlet and outlet in the router so as to facilitate the radiation of the router cabinet.

zThe cabinet and workbench have good radiation systems.

zThe cabinet and workbench are firm enough to support the weight of the router and other installation accessories.

zThe cabinet and workbench are well grounded.

3.3Tools and Devices Required

1)Tools required

zPhillips screwdriver

zFlathead screwdriver

zESD-preventive wrist strap

2)Connection cables z Power cable

z Console cable z Auxiliary cable z Ethernet cable

z Interface cable for selected modules

3)Required Devices

zEthernet HUB or LANSWITCH

R2600/3600 series have been designed according to the size of the standard 19-inch cabinet, and their dimensions are respectively:

Quidway R3680, R3680E: Width x height x depth = 440mm x 86mm x 400mm

Quidway R2630, R2630E, R2631, R2631E, R3640, and R3640E:

Width x height x depth = 440mm x 43mm x 400mm

Quidway R2620, R2621: Width x height x depth = 440mm x 86mm x 300mm

As shown in Figure 4-2, the flow for installing the router is as follows:

Step 1: Check the grounding condition and secureness of the cabinet. Secure the bracket to both sides of the front/rear panel of the router.

Step 2: Place the router on one of the trays in the cabinet. Move the router to a proper position along the guide rail in the cabinet. Leave an appropriate space between the router and guide rail.

Step 3: Screw the bracket to the fixed guide rail at both sides of the cabinet.

In this way, the router is firmly fixed to the cabinet through the tray at each slot in the cabinet and the bracket of the router.

Figure 4-2 Mechanical installation of the Quidway R26/ 36 series

4.2.2 Installing the Router on Workbench

In most of the cases, you do not have a standard 19-inch cabinet. Then, you can place the routers on clean workbenches. This is a simple operation. During this operation, the operator:

zMust ensure the stability and good grounding of the workbench.

zMust reserve a 10cm for heat-dissipation around the router.

zDo not place any heavy object on the router.

Quidway R2600/3600 Series Modular Routers	Installation

Step 4: Check that the power indicator in the rear panel of the router is on. It is on when the power cable is correctly connected.

4.3.2 Connecting Ground Cable

Warning:

The normal connection of the router’s ground cable is the primary guarantee for the anti-lightning and anti-interference capability of the router, so you must connect the ground cable carefully.

The AC input connector of R2600/3600 series comes with an AC noise filter unit, whose central ground is directly connected with the cabinet, forming the so-called chassis ground (also called the protection ground). This chassis must be well grounded so that the induction power and leakage power can be released to the ground to improve the whole router’s performance to withstand electromagnetic interference. This ground also provides protection against the lightning and over-voltage likely to be caused by the external network cable such as the E1 interface and ISDN cables.

The ground point of the chassis is located near the AC power and switch at the back of the cabinet, as shown in Figure 4-7. The point shall be connected to the ground.

Ground point

Figure 4-7 Ground point on the chassis

Please connect this point to the ground with a ground cable, and make sure that the ground resistance is not greater than 5-ohm. If the router is installed in a standard 19inch cabinet, then this cabinet should be grounded in the same way.

Warning:

The router must be well grounded for the normal working; otherwise it cannot guard against lightning, and is likely to cause damage to the router and the far-end equipment connected with this router!

4.4 Connecting Interface Cable on Main Control Panel

Note that Console and AUX interface cannot be used at the same time. You can only choose either of them.
