qualified personnels should be allowed to
install or replace the equipment.
Installing
tools and equipment
The
tools and equipment needed possible for installation are not provided as the
standard equipment with the router , so pleade prepare them by yourself.

fowllowing are tools and equipment needed for typical Router installation:
1.
screw-driver
2.
static-pretentive
wrist strap
3.

The
Router chassis can be set on a desktop or mounted in a rack or other flat
surface .The operation steps of the chapter will meet your network installation
need well , including the following sections:
Setting the chassis on a desktop
Mounting the chassis in a rack
Setting
the chassis on a desktop
The
D-Link 2621Modulor
Router can be put on smooth , flat and secure desktop directly.
Note : Do not put anything that weighs more than 10 pounds(4.5Kg )on the top of the router.Over weight on the top could damage the chassis.
Mounting the chassis in a rack
The
router is installed on the chassis by brackets and mounted the chassis with the
front panel forward . Installing as the following :
Note
:
The
above example only show how to connect the brackets to one side of chassis . The
second bracket connects to the opposite side of the chassis.
After
the brackets are secured to the chassis , you can rack-mount it .As the
following figure :
The
D-Link 2621
modulor Router has 1 console port and 1 remote AUX port. This section introduces
the two ports and the usage .
1. Console port
Console
port speed is 1200bps—115200bps,
standard RJ45
no indicator lamp, parity ckeck is optional and has flaw control.It
connects to the terminal by special console cable ( such as : terminal
STAR-510G),or to PC serial port and terminal analog software( such as : windows
super terminal ) to configure or control the Router .Cable is supplied
with the Router. Communication parameter of terminal serial port can be configured
: speed—9600pbs, 8-bit data bits,1-bit stop bits, no parity and no flaw
cintrol.
RJ-45
connnecter used by console port is as following picture ,RJ45
pin adapted to RJ45
socket, and the number is 1—8 from left to right .,
The
Console port of D-Link 2621
modulor Router connects to computer as the following picture :

The
console cable
used to D-Link 2621
modulor Router Console
port external connecting is as the following picture :
The
cable is used to connect D-Link
2621
modulor Router Console
port
and external console terminal equipment , with one port of RJ45 8—pin, and
another port of DB25and DB9. RJ45
pin insert into a D-Link2621
modulor Router Console
port socket,the
DB25
and DB9
port can choose to use according to the terminal serial port .The
inter connecting is as the following . The console cable numder is RLC0301 .
2.AUX
port
Remote console port ——AUX port speed is 1200bps—57600bps,RJ45 interface,parity chack is optional and has flaw control. The AUXport can connect to every kinds of async terminal or supported by MODEM far control and configuration .AUX port communication parameter also can be configured as::speed—9600bps、8-bit data bits , no parity , 1-bit stop bits.
The AUX port special cable is used to connect AUX port and external Async terminal equipment with one port of RJ45 8-pin and another port 25 pin (DB25) and 9 pin(DB9). RJ45 port insert into D-Link 2600 seriel Router AUX port socket.The DB25 and DB9port can choose to use according to the requirement of async serial port .AUXport conception is similar to Console port.The inter connecting of the cable is as the following ,the cable number is RLC0302。

Ethernet port connecting shows as the following;
UTP
port can connect to HUB
by twist-pair as the following picture:
When
two D-Link
2621modulor
Router connected interactively, UTP(twist-pair)
cross-over cable can be used . TP(twist-pair
)
cross-over cable also can be used to connect one Router to CPU LAN card
twist-pair port directly . Thus , one HUB can be lieved out on LAN. However, the
HUB must be used when more than two Ethernet port connect. UTP
cross connecting is shown as the following piture:
The
color arrangement of cross-over twist-pair cable in the piture is depend
on EIA/TIA
568A
specification:
High
speed serial port supports V.24/V.28(EIA/TIA-232), V.35 physical layer protocol, providing
DB60interface. Users may select corresponding interface cable to connect a
specific device.
Under
any speed, there is a communication distance limit for the serail port.
Basically, the lower the speed, the further the communication distance .
All serial port
signals have distance
limit. Over the distance, signals
will be weaken even lost
. The following shows the speed and the distance limit of different
port.
