guide 1:                  TYPES DE CABLES RJ 45 


  1- Straight-through Cabling :

  In a straight-through cable, the colored wires are in the same
sequence at both ends of the cable.

Tx+	    1  	 1	Tx+
Tx-	    2	 2      Tx-
Rx+	    3	 3      Rx+

-	    5	 5	-
Rx-	    6	 6	Rx-
-	    7	 7	-
-	    8	 8	-

  2-Crossover Cable:

  In a crossover cable, the first (far left) colored wire at one end
of the cable is the third colored wire at the other end of the cable.

Signal	Pin	Pin	Signal
Tx+	1	3	Rx+

Rx+	3	1	Tx+
-	4	4	-
-	5	5	-
Rx-	6	2	Tx-
-	7	7	-
-	8	8	-

  3-Rolled Cable:

  In a rolled cable, the colored wires at one end of the cable 
are in the reverse sequence of the colored wires at the other end
of the cable.

Signal	Pin	Pin	Signal
-	1	8	-
-	2	7	-
-	3	6	-
-	4	5	-
-	5	4	-
-	6	3	-
-	7	2	-
-	8	1	-

Note: CAB-OCTAL-ASYNC, the 8-port RJ-45 adapter that is used with the 
Cisco 2509, 2510, 2511, and 2512, is the same as a rolled cable.

guide 3:                  DB9 Connectors 



General Information: 

 
A typical cable using DB9 connectors made by CompuCable. 


The DB9 connector is used by serial port devices. On a typical PC
the DB9 connector is located on the back of the computer and is 
assigned to one of the Com Ports. It has 9 pins arranged in two 
rows one on top of the other. The top row has 5 pins and the lower 
row has 4 pins.

Pin Signals: 

.Pin 1 - Received Line Signal Detect 
.Pin 2 - Received Data 
.Pin 3 - Transmitted Data 
.Pin 4 - Data Terminal Ready (DTR) 
.Pin 5 - Signal Ground 
.Pin 6 - Data Set Ready (DSR) 
.Pin 7 - Request to Send (RTS) 
.Pin 8 - Clear to Send (CTS) 
.Pin 9 - Ring Indicator (RI)

guide 4:          Console Port Settings for
                     terminal Connection


Before you connect a terminal to the console port,configure
the terminal to match the router console port as follows:

   .9600 baud 
   .8 data bits 
   .no parity 
   .2 stop bits (9600 8N2) OR 1 stop bit* 
     *Dependant on the router

Types of Console and AUX Connectors:

As described in the following table,Cisco routers have 
three types of console and AUX connectors:

   .RJ-45 

   .DB-25 DCE 

   .DB-25 DTE 

There are three styles of RJ-45-to-DB-25 connectors: 
DCE style (modem), DTE style, and DCE style (non modem).
Each one has a different role. Generally, DTE is for 
terminals, DCE (modem) is for modems, and DCE (non-modem)
is obsolete.

Note: You can change a DCE style (non modem) to a DCE style (modem)
by moving pin 6 to pin 8.

Cabling for console and AUX port:
 
RJ-45 Cables 
RS 232 Straight-through Cable 

Types of RJ-45 Cabling:

Cisco products use the following types of RJ-45 cables:


   .Straight-through
     
   .Crossover
    
   .Rolled
     
   .RJ-45 to DB9 female

Note: The console port does not support modem control or hardware
flow control.

How to Identify an RJ-45 Cable:


To identify the RJ-45 cable type, hold the two ends of the 
cable next to one another so you can see the colored wires
inside the ends, as shown in the following figure.



There are three types of commonly used RJ-45 cabling:
straight, cross and rolled. If you hold the two ends 
of an RJ-45 cable side by side, you'll see eight colored 
strips, or pins, at each end. If the order of the colored
pins is the same at each end, then the cable is straight. 
If the order of the colors is reversed at each end, then 
the cable is rolled.


Adapters:

There are two types of adapters needed to connect a PC to a router.
 
   .RJ-45-to-DB-9 Adapter 
   .RJ-45-to-DB-25 Adapter 
 
RJ-45-to-DB-9 Adapter:

This adapter connects a router to a PC though a COM port.

RJ-45-to-DB-25 Adapter:

This adapter connects a router to PC through a serial port.

guide 5:          Auxiliary Port Signals and Pinouts
                     

Use the thin, flat, RJ-45-to-RJ-45 roll-over cable and RJ-45-to-DB-25 
male DCE adapter (labeled "MODEM") to connect the auxiliary port to a modem.
the figure below  shows how to connect the auxiliary port to a modem. 
the table lists the pinouts for the asynchronous serial auxiliary port, 
the RJ-45-to-RJ-45 roll-over cable, and the RJ-45-to-DB-25 male DCE adapter
(labeled "MODEM").
