2 P R EPARING TO I NSTALL THE R OUTER Safety W arnings As you prepar e to install your router , consider the following safety guidelines: ■ Switch off the power supply befor e connecting the cables. ■ Keep the router far away from any heat sour ce.
20 C HAPTER 2: P REPARING TO I NSTALL THE R OUTER the router . If the equ ipment is always very hot, the aging process of insulating materials accelerates, which affects the r eliability of the r outer and even its operational lifetime. The requirements fo r the temperatur e and humidity of the router installation site are listed in Ta b l e 1 .
Preventing Lightning Damage 21 T o prevent damage caused by the static electricity , insure that: ■ The equipment is grounded ■ The equipment room is dust-proof ■ Adequate temper ature and humid.
22 C HAPTER 2: P REPARING TO I NSTALL THE R OUTER Workbench Requirements Whether you install the router in a cabinet or directly place it on the workb ench, it is necessary to ensure that: ■ There is spacing r eserved at the air inlet and outlet in the router so as to facilitate the ventilation of the r outer cabinet.
3 I NSTALLING THE R OUTER There ar e two ways you can install your router: ■ On a vertical surface ■ On a workbench Mounting the Router on a V ertical Surface The Router 3000 series routers can be.

Connecting the Router to the Console Terminal 25 Figure 3 illustrates the power supply . Figure 3 Router 3000 Power Supply T o connect the AC power cord: 1 T ur n off the power to the router . 2 Connect the output of the power supply to the pow er input on the rear panel of the router .
26 C HAPTER 3: I NSTALLING THE R OUTER T o co nfigure the r outer through the console terminal: 1 T ur n off power to the router . 2 Select a console terminal — The c onsol e port can be either a standar d ASCII terminal with an RS-232 serial interf ace, or a PC.
Connecting the Router to the WAN 27 When connecting the router to a hub or a LAN switch, use the straight-through network cable. 3 Connect one end of the Ethern et cable to the appropriate Ethern et module on the rou t e r . 4 Connect the other end of the Ethernet cabl e to the Ether net interface of the Hub or the LAN switch.
28 C HAPTER 3: I NSTALLING THE R OUTER T o co nnect the AUX cable: 1 T ur n off power to the router . 2 Plug the RJ-45 connector of the AUX cable into the AUX port of the router . 3 Connect the DB-25 or DB-9 adapter of the AUX cable t o the serial interface of the analog modem.
Connecting the Router to the WAN 29 In general, the asynchronous serial interface is connected to a modem or a terminal adapter (T A) to act as the dial-up interface. In this case , it is unnecessary to determine whether the device is DT E or DCE, you must only select the appropriate baud rate.
