■
Ethernet port
■
Synchronous/asynchronous serial port
■
Auxiliary (AUX) port
■
ISDN BRI S/T and U port
■
CT1/PRI port
■
E1/CE1/PRI port
These features allow you to combine the various networking technologies, such as
PSTN/ISDN, FR (Frame Relay), X.25, leased line, and T1 line. These multiple ports
also allow Router 3000 series routers to interoperate with the products of other
manufacturers.
Router 3000 routers use three types of memory:
Router 3012
■
Synchronous Dynamic Random Access Memory (SDRAM) — Saves router
operation system software
■
Flash memory — Saves router program files, configuration files and so on
■
Boot ROM — Saves the boot and initialization programs of the router

■
Connecting the Router to the Ethernet
■
Connecting the Router to the WAN
■
Verifying the Installation
This section provides guidelines for preparing your site and router for installation.
Before installing your router, consider the following safety guidelines:
■
Switch off the power supply before connecting the cables.
■
Keep the router far away from any heat source.
■
To ensure normal heat dissipation, do not stack routers.
■
Do not keep a router in a damp place, and prevent liquid from getting into the
router.
■
Ensure that the neutral point of the power is grounded properly, to avoid
personal injury.
■
Ensure that the power is off before plugging or unplugging the interface cards,
modules and cables of the router.
■
Before removing the chassis, disconnect all the power cords and external
cables.
■
To avoid damage to the router, connect all the cables correctly. Never connect
telephone cables (including the ISDN lines) to the console or AUX port.
20
CHAPTER 2: INSTALLING THE ROUTER
■
During the installation, wear an ESD (Electro-Static Discharge) preventive wrist
strap and ESD-preventive gloves. See “Static Electricity” on page 20 for
additional information on ESD prevention.
3Com recommends that you use an uninterrupted power supply (UPS) with your
router.
General Site
Requirements
The environment of the installation site influences the performance and lifetime of
the router. The installation site for your router should meet the following
requirements for temperature and humidity, dust, gases, static electricity, and
electromagnetic discharge.
Temperature and Humidity
To ensure normal operation and to prolong the operational lifetime of the router,
the temperature and humidity of the equipment room must be within controlled
limits. The requirements for the temperature and humidity of the router
installation site are listed in Table 22.
Table 22 Temperature and Humidity Requirements
Temperature
Relative humidity
00 to 400C (320 to 1040F)
5% to 85%
Dust
Dust is harmful to the safe operation of the router. The specifications for the dust
content and diameter of the granule within the equipment room are listed in
Table 23.

SNMP Management
For help managing routers on your network, you can use 3Com Network
Supervisor software to discover, map, and display network links and IP devices.
To allow Network Supervisor to monitor your routers, you must first configure
SNMP V1 and SNMP Trap support with the following commands:
[3Com]snmp-agent sys-info version v1
[3Com]snmp-agent community read <read-community-string>
[3Com]snmp-agent community write <write-community-string>
[3Com]snmp-agent trap enable
[3Com]snmp-agent target-host trap address <addr> parameter
v1 securityname <security-name-string>
In this example, <addr> is the address of the PC on which you have installed Network
Supervisor.

Applications and
Configuration Files
Using FTP
Uploading files involves transferring them from a PC running the FTP client to a
router running the FTP server, through the router’s Ethernet port. This is called a
put operation.
Downloading files involves transferring them from the FTP server on the router,
through its Ethernet port, to the PC running the FTP client. This is called a get
operation. All FTP clients, including local and remote users, who are connected to
a router can upload and download if they pass user authentication.
Creating a Local FTP Upload/Download Configuration
To transfer files using FTP, you must create the appropriate configuration, as shown
in Figure 23 and Figure 24, and described in the following procedures.

contact your Service representative.
Nothing is Displayed
on the Terminal after
Power-On
After the system runs the power-on self-test (POST), if the system operates
normally, the start-up information is displayed on the console terminal. If the
configuration system has a fault, the terminal may display nothing.
If the terminal does not display any information after the POST, verify that:
■
The power system is operating normally.
■
The console cable is connected correctly.
If the power system is normal and the console cable is connected properly, there
may be something wrong with the console cable or the HyperTerminal
parameters. Check the cable or the parameters.
HyperTerminal parameters should have the following values:
■
Baud — 9600
■
Data bits — 8
■
Stop bit — 1

The Ethernet cable uses an RJ-45 connector and category 5 twisted pair cable.
The Router 3000 series routers provide a fixed 10/100BASE-TX fast Ethernet port
that uses category-5 twisted pair cable, as shown in Figure 29
Figure 29 Ethernet Cable Assembly
The Ethernet cables are classified as straight-through network cable and crossover
network cable. They have the following features:
■
Straight-through network cable — The sequences of the wires crimped at the
RJ-45 connectors of the two ends are the same. The cable is used in the
connection between a terminal device, such as a PC or a router, and the Hub or
Serial Port Cable
53
LAN Switch. Straight-through network cables are delivered along with the
router.
■
Crossover network cable — The sequences of the wires crimped at the RJ-45
connectors of the two ends are different. The cable is used in the connection
between the terminal device, such as a PC or a router, and another terminal
device. You can create this cable yourself, if necessary.

You can use Table 28 as a reference while distinguishing or preparing the two
kinds of Ethernet cables. While preparing the Ethernet cables, follow the
chromatogram given in this table to arrange the wires. Otherwise, communication
quality will be affected even though the equipment at two ends is connected.
Serial Port Cable
The synchronous/asynchronous serial port cable is connected to a DB-50
receptacle. You must select the appropriate cable for the protocol.
54
CHAPTER A: OPTIONAL CABLE SPECIFICATIONS
Synchronous and
Asynchronous mode
V.35 and V.24 (EIA/TIA-232) standards support synchronous operating mode,
while only V.24 (EIA/TIA-232) standard supports the asynchronous operating
mode. The maximum transmission distance and baud rate of the signal vary with
the operating mode. See Table 29 for details.

CAUTION: The baud rate should not exceed 64 Kbps when the V.24 cable
operates in synchronous mode.
DTE and DCE mode
The synchronous serial port can operate in both DTE mode and DCE mode. For
two devices connected directly, one device should operate in DTE mode, and the
other device should operate in DCE mode. The DCE mode device provides a
synchronous clock and specifies the transmission rate, the DTE mode device
accepts the synchronous clock and communicates at the specified transmission
rate. Usually, the router serves as the DTE device. To determine whether the device
is a DTE or a DCE, refer to the user manual for the device. Table 30 helps identify
DTE and DCE devices.
Table 30 Typical DTE and DCE
Type of
Equipment
Type of Interface
Typical Equipment
DTE

Modem, multiplexer or CSU/DSU
In general, the asynchronous serial interface is connected to a modem or a
terminal adapter (TA) to act as the dial-up interface. In this case, it is unnecessary
to determine whether the device is DTE or DCE, you must only select the
appropriate baud rate.
