Router chassis installation

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 :

 

Connecting to console port

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 1200bps115200bps, 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。

Connecting to Fast Ethernet interface

10/100Mbps siutes to Ethernet portsupplies UTP (RJ45) interfacewith ACTLink100Mbps indicator lamp, can be connected to HUB  on UTP port through  twist-pair. UTP port number-order is similar  to Console port , the order is as the following table:

1.        10/100Mbps Ethernet port  and HUB connecting picture is as the following :

UTP port can connect to HUB by twist-pair as the following picture:

  Color arrangement of twist-pair in the picture  is depend on  EIA/TIA 568A specification:

 

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:  

Connecting to Serial port

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.
