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 attent ion. T hough this operat ion will not do an y dam age to t he ro uter
or endanger the operator, it may affect the normal operation of the router.
Please follow the f ollowing s afety recom m endations duri ng the ins tallation a nd use of
the router:
z Keep the router away from water or any wet place.
Keep the router away from any heat source.
z
z Make sure that the router is normally grounded.
z Wear ESD-preventive wrist strap during installation.
z Do not hot unplug the modules of the router.
z Do not hot unplug any cable.
z Always use UPS.
Chapter 3
Installation Preparations
3.2 Installation Conditions
R2600/3600 series must be used indoors. T o 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. Som etimes this will r esult in change to the m echanical
performance of the materials and rusting of the metal components. If the relative
humidity is too lo w, the fastening screw will bec ome loosen due to shrink age of the
isolation spacer. In an environment with dry climate, the static electricity may be
produced, putting the CMOS of the router to ris k. High tem perature is of the gr eatest
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:

Quidway R2600/3600 Series Modular Routers
Table 3-1 Humidity requirement in the equipment room
Temperature Relative humidity
Chapter 3
Installation Preparations
Normal operating condition
15OC to 30OC0
Note:
Safety operating
condition
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 n ormal operation of R2600/3600 ser ies. 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.
Normal operating condition
O
Cto 45OC 40% to 65% 10% to 90%

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 rust ing and the aging pr ocesses of
certain parts. The eq uipment room should be pr otected from the invasio n of harmful
gases such as SO

3.2.3 ESD-Preventive Requirements
Although many antistatic considerations have been given to R2600/3600 series,
damage to the router’s circ uit or e ve n th e whole equipment may still h app en when the
static electricity exceeds the tolerance threshold.
In the communication network to which the routers are connected, static induction
mainly comes from:
External electric fields such as outdoor high voltage power line or thunder.
z
z Internal environment like flooring materials or the whole equipment structure.
Thus, the following should be considered to safeguard the equipment against the static
damage:
z Make sure that the equipment and the floor are well grounded.
z Make sure that dust-proof measures are taken.
Maintain an appropriate humidity and temperature.
z
z Wear an ESD-preventive wrist strap and uniform when contacting the circuit
board.
Place the uninstalled circuit board on the antistatic workbench, with its face
z
upward, or put it into the electromagnetic shield bag.
z When observing or rem oving the un insta lled cir cuit bo ard, pleas e touch th e ed ge
of the circuit board, and avoid contacting the devices on it.

3.2.4 Anti-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 (incl uding the grounding s ystem) or conducting li ne (power line,
signal line and transmission line etc.).
So the following should be considered:
z Take effective measures to prevent the power system from being interfered with
by the power grid system.
Separate the working ground of the router from the grounding device of the power
z
supply equipment or anti-lightning grounding device as far as possible.
Keep the router far away from the radio launcher, radar launcher, and high-
z
frequency devices working in high currents.
z Use electromagnetic shielding when necessary.
3.2.5 Lightning 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

Ensure the shell of the chassis is well grounded through the ground wire.
z
z Ensure the neutral point of the socket of AC power supply is well grounded.
z To enhance the lightning protection capability of the power supply, a lightning
arrester could be installed at the input end of the power supply.
z As 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.
3.2.6 Workbench Requirements
No matter whether you are to install the router in the cabi net or direct ly place i t on the
workbench, it is necessary to ensure that:
z There is spacing reserved at the air inlet and outlet in the router so as to facilitate
the radiation of the router cabinet.
z The cabinet and workbench have good radiation systems.
The cabinet and workbench are firm enough to support the weight of the router

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.
Chapter 4
Installation
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 gr ound cable, and make sure that the
ground resistance is n ot greater t han 5- ohm. If the router is inst al led in a s tan dard 1 9inch 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!

8.5 1FE/2FE Module
8.5.1 Introduction
I. Functions
FE (Fast Ethernet) is mainly responsible for the communication between the router and
the LAN.
R2600/3600 series suppor t two k inds of FE m odules: 1F E, 2FE, whi ch are diff erent in
the following aspects:
1FE module provides one RJ-45 connector of 100Mbps Ethernet
z
2FE module provides two RJ-45 connectors of 100Mbps Ethernet
z
The FE module (1FE/2FE) supports the following functions:
z If Category 5 twisted pair is used, 100-meter transmission distance can be
supported.
8-5
Installation Manual
Quidway R2600/3600 Series Modular Routers
z The FE interface can work at the speed of 100Mbps or 10Mbps, and can
implement auto-sensing.
The FE interface can work in full-duplex or half-duplex mode; the former is more
z
commonly used.
II. Arrangement of Ethernet interfaces
The interfaces of FE module should be arranged according to the following principle:
z The fixed Ethernet interface of R2630/R2620/R2630E is Ethernet0, and the
interface number of the first swappable module starts from Ethernet1.
R2631/R2621/R2631E has two fixed Ethernet interfaces: Ethernet0 and Ethernet1.
The interface num ber of the first swappable module s tarts from Ethernet2. The
first Ethernet interface of the R3640/3680/R3640E/R3680E is Ethernet0.
The number of the Ethernet interf ace will increase in ascending order, starting
z
from slot 0.
z In the same 2FE board, the interface sequencing is the same as that of 2FE panel.
For example, if a 1FE is plugged into slot 1 of the Quidway R2630 and 2FE is plugged
into slot 2, the num ber for the Ethernet interface in s lot 1 is Ethernet1, and the two
Ethernet interfaces are numbered Ethernet2 and Ethernet3.

1) When preparing the network cable, please use the twisted cable by preference to ensure the
electromagnetic compatibility.
2) The Ethernet interface between the 1FE/2FE module and the configuration terminal can not be
connected directly through the straight-through cable. Use crossover network cable to connect them
directly.
3) You can use HUB to connect the straight-through cable of the 1FE/2FE module’s Ethernet interface to
the Ethernet interface of the configuration terminal.
8.5.6 Connecting Interface Cable
Step 1: If the Ethernet cable is a straight-through cable, plug one end of the cable to an
Ethernet interface of the FE module, and plug another end to the HUB.
Step 2: Power on the r outer and chec k the status of READY i ndicator on th e router’s
front panel. It is on when the module has completed self-check and works normally . It is
off when the module fails to pas s the se lf - c heck , and please contact the loc a l a gent of
Huawei.
Step 3: After powering on the system, please check the s tatus of the LIN K i ndic ator of
FE. It is on when the line is connected and off when the line is disconnected, in the latter
case, please check the line.
Caution:
When connecting the cables, observe the identifiers on the interfaces to avoid wrong connection and
damage to the module and the router.

8.6 2SA/4SA Module
Warning:
Plugging or unplugging the interface cable of 2SA/4SA module is prohibited when the router is powered on,
otherwise, the equipment or the module may be damaged.
8.6.1 Introduction
Caution:
Chapter 8
Function Modules
Before connecting the sync/async serial interface, please make sure of the following:
1) The type of device (sync/async, DTE/DCE, etc.) connected to the sync/async serial interface, and the
signal standard, baud rate, and synchronization clock as required by the access device.
2) When the EIA/TIA-232 cable is used, the baud rate in synchronous mode cannot exceed 64Kbps.
I. Functions of 2SA/4SA
SA (sync/async seria l inter f ace) s upports synchronous and asynchronous modes. It is
mainly responsible for receiving/transmitting and processing data at the s ync/async
serial interface.
R2600/3600 series support two kinds of SA modules: 2SA, 4SA.
II. Arrangement of 2SA/4SA serial interfaces
The interfaces of 2SA/4SA module are arranged according to the following rules:
z The first sync/async serial interface is Serial0.
z In the s am e 2SA or 4S A m odule, the inter fac e sequ encing is t he sam e as that of
the module panel.
Starting from slot 0, the interface of the f irst SA ranges from Serial0 to Serial1
z
(2SA) or from Serial0 to Serial3 (4SA); the interface of the second SA ranges from
Serial2 to Serial3 (2SA) or from Serial4 to Serial7 (4SA), and so on. For example,
A 4SA is respectively plugged into slots 1 and 3 in the Quidway R3680. So the four
sync/async serial in terfaces in slot 1 ar e numbered from Ser ial0 to Serial3, and
those in slot 3 are numbered from Serial4 to Serial7.

Quidway R2600/3600 Series Modular Routers
III. Introduction to DTE and DCE
2SA/4SA are usual ly connected to Modem . When the y are used as dialup ports, it is
necessary to set their baud rates.
The synchronous serial inter face can work in either DTE mode or DCE mode. Two
devices directly connected should work in DTE and DCE modes respectively. The DCE
side provides the synchronization clock and specifies communication rate, and the
DTE receives the synchronization clock and communicates at the specified rate.
The router normally works as a DTE. To know whether the specific equipment
connected with the router is DT E or DCE, please ref er to the m anual shi pped with th e
equipment. In addition, Table 8- 5 als o helps you ide ntif y the equ ipment type.

IV. Baud rate and transmission di stance on the sync/async serial interface
In different operating modes, the sync/as ync seria l interfac e sup ports different el ectric
signals and baud rates, so different cables should be selecte d in different situations.
The maximum transmission distance of the signal and the baud rate set are associated
with the selected cable. Please refer to the following table for the specific values:

Warning:
Plugging or unplugging the interface cable of the 8AS/16AS module is prohibited when the router is
powered on, otherwise the equipment or the module may be damaged.
8.7.1 Introduction
I. Functions of 8AS and 16AS
AS stands for asynchronous serial interface.
Quidway R2600/3600 series support two kinds of AS module: 8AS, 16AS.
Chapter 8
Function Modules
8AS is mainly responsib le for receiving, transm itting and processing data streams on
the 8-port async interface.
16AS is mainly responsible for receiving, transmitting and processing data streams on
the 16-port async interface.
8AS and 16AS both features the following:
z The maximum speed per line is up to 115.2Kbps, supporting terminal access
service and asynchronous leased line service. In addition, the asynchronous serial
interface can serve as a dialu p access server for the small- and medium -sized
ISPs. Or, it can interc onnect with 8 (8AS) LANs or 16 (16AS) LANs through th e
asynchronous dialup line.
z The interface cable for the 8AS module is a 1-to-8 connection cable: its DB-68 end
is connected with the 8AS module and the DB-9/DB-25 end is connected with the
network. The interface cable for the 8AS module is a “1 to 16” connection cable: its
DB-200 end is connected with the 16AS module and the DB-9/DB-25 end is
connected with the network.
II. Arrangement of interfaces of 8AS and 16AS
The interfaces of 8AS and 16AS are arranged according to the following rules:
z The first interface is Async0.
Starting from slot 0, the interfac e of the first AS ranges from Async0 to Async7
z
(8AS) or from Async0 to Async15 (16AS). The inter f ac e of the sec ond AS ra nges
from Async8 to Async15 (8AS) or from Async16 to Async31 (16AS), and so on.
z In the same 8AS/16AS, the order for the interfaces is the same with the numbering
order on 8AS and 16AS.

For example, an 8AS is plugged to slots 1 and 4 of the Quidway R3680 series
respectively. Then the 8-port asynchronous serial int erfaces in slot 1 are numbered
from Async0 to Async7, and those in slot 4 are numbered from Async8 to Async15.

8.7.6 Connecting Interface Cable
Step 1: Connect the 8AS and 16AS interface cable:
z For the 8-port asynchronous serial interface cable, connect its 68-pin male
connector to the 68-pin fem ale interface. The eight DB-25 connectors or DB-9
connectors of the cable can be respectively connected to different network ports.
z For the 16-port asynchronous serial interface cable, connect its 200-pin male
connector to the 200-pin f emale interf ace. The sixtee n DB-25 connect ors or DB9 connector of the cable can be respectively connected to different network ports.
Step 2: Screw up the k nob to fix the 8 AS/16AS interf ace cable to the DB- 68 interf ace
(8AS) or DB-200 interface (16AS).
Step 3: Power on the system and check the status of READY indicator on the f ront
panel of the router. It is on when the module has completed self-check and works
normally. It is off when the module fails to p ass the self-check. In this cas e, please
contact the local agent of Huawei.
Step 4: Power on the system and check the states of the indicators on the front panels
of 8AS and 16AS:

z LINK indicator of 8AS is on when the li ne is connected, and off when the link is
disconnected.
LINK indic ator of 16AS is on whe n the line is connected, an d off when the lin e is

Caution:
When connecting the cables, observe the identifiers on the interfaces to avoid wrong connection and
damage to the module and the router.

Caution:
If the interface cable of 1E1/2E1/4E1 is led out to the outdoor, a special lightning arrester should be
installed at the input end of the signal line to obtain better lightning protection effect.
8.8.1 Introduction
I. Module function
E1 is an abbreviated term for cE1/PRI module.
The main function of E1 module is to implement the receiving, transmission, and
processing the E1 data str eams. In addition, it provides access to cE1, im plementing
the ISDN PRI function so that one board can serve multiple purposes.
R2600/3600 series routers support three models of cE1/PRI module, i.e., 1E1, 2E1 and
4E1.
II. Arrangement of module interfaces and order
The method for operating on th e cE1 m odul e is diff erent from that for operating on the
other modules: each cE1 interface is a Controller E1. The arrangement of Controller E1
interfaces is as follows:
The first Controller E1 interface is E1 0.
z
Starting from slot 0, the first Controll er E1 interface number for the next slot is
z
equal to the last Controller E1 interface number of the previous slot plus 1.
8-33
Installation Manual
Quidway R2600/3600 Series Modular Routers
z In the same interface unit, the order for the interface numbers is the same as that
for the numbers on the module.
For example, in the Q uidway R3680, plug a 4E1 into slot 1 and a 2E 1 i nto s lot 3. T he
four cE1/PRI interfaces in slot 1 are numbered from Controller E1 0 to Controller E1 3,
and the two cE1/PRI interfaces in slot 3 are numbered from Controller E1 4 to
Controller E1 5.
Caution:
At the corresponding Controller E1, you can bind the timeslot of cE1 to the corresponding Serial0 with the
configuration command. For details, please refer to VRP User Manual - Configuration Guide (V1.5).
