What is a Cisco terminal server?
A terminal server is a router with multiple, low speed, asynchronous ports that are connected to other serial devices, for example, modems or console ports on routers or switches. The terminal server allows you to use a single point to access the console ports of many devices.

How do I connect to a Cisco console without a serial port?
You will have to either buy a parallel to serial converter and then use a db9 adapter and cisco router console cable to access the router. OR you can buy, what is called as USB PDA adapter. This is a USB to serial port converter. Check this vendor.
What type of cable is used to connect to a Cisco console port?
The console port uses an 8-pin RJ-45 connector. If you did not order a console cable, you need to provide an RJ-45-to-DB-9 adapter cable to connect the switch console port to a PC console port.

Why does Cisco use CLI instead of GUI?
Ease of Use: CLI enable users to type manual command in order to perform the desired task whereas in GUI users provided visuals to communicate with the data switch. So the beginners will pick up a GUI much faster than a CLI.
What is CLI routing?
CLI Routes These white routes display the caller ID when the call connects to the recipient. The Caller ID visible to the receiver is actual information. The white routes are “legal”. By legal, it refers to the route termination on any end.
Why does Cisco use CLI?
The Cisco IOS command-line interface (CLI) is the primary user interface used for configuring, monitoring, and maintaining Cisco devices. This user interface allows you to directly and simply execute Cisco IOS commands, whether using a router console or terminal, or using remote access methods.

What cable is used for Cisco 2509?
The Cisco 2509 - 2512 series routers use a 68-pin connector and breakout cable. This cable provides eight RJ-45 rolled cable async ports on each 68-pin connector. (See CAB-OCTAL-ASYNC Cable Pinouts .) You can connect each RJ-45 rolled cable async port to the console port of a device. The 2511 router allows for a maximum of 16 devices to be remotely accessible. In addition, the NM-16A or NM-32A high-density async network modules are available for the Cisco 2600 and 3600 series routers to provide the same function. (See Understanding 16- and 32-Port Async Network Modules .) For more information on cabling refer to the Serial Cable Connection Guide and the Cabling Guide for Console and AUX Ports.
How to make a terminal server accessible?
In order to make the terminal server accessible, assign a registered public Internet address, and locate the server outside the firewall. When you do so, firewall issues do not interrupt your connection. You can always maintain connectivity to the terminal server and access the connected devices.
How to exit telnet session?
Use the escape sequence Ctrl-Shift-6 then x to exit the current Telnet session.
What is a 68 pin connector?
Note: The async ports from the 68-pin connector are data terminal equipment (DTE) devices. DTE to DTE devices require a rolled (null modem) cable and DTE to data circuit-terminating equipment (DCE) devices require a straight-through cable. The CAB-OCTAL-ASYNC cable is rolled. Therefore, you can connect each cable directly to the console ports of devices with RJ-45 interfaces. However, if the console port of the device to which you connect is a 25-pin interface (DCE), you must use the RJ-45 to 25-pin adapter marked "Modem" (to reverse the "roll") in order to complete the connection.
How to connect to terminal server through the internet?
Use the ip default gateway statement, and point to the the next hop router on the Internet. This command enables you to have connectivity to the terminal server through the Internet even if routing is not enabled. For example, the terminal server is in ROM monitor (ROMMON) mode as a result of a bad reboot after a power outage.
How to connect to the console of the target router?
Use a PC/dumb terminal to connect directly to the console of the target router. The target router is the device connected to the terminal server. This step helps you identify the presence of a port issue.
Can you configure a single modem on a terminal server?
You can also configure a single modem on the auxiliary port of the terminal server, to provide dial-up service to the other devices when network connectivity fails. This document shows how to configure a terminal server to access only the console ports on other routers through Reverse Telnet.
Real World Application
This lab will teach you how to configure a Cisco Access Server which can be used to access all your Cisco Lab devices from a single point of administration.
Lab Prerequisites
Complete Lab 1.2 before attempting this lab or have a current Cisco console session open to the access server.
How many pins does a Cisco 2509 have?
Now there are actually two different versions of the 2509 and 2511 routers. There is the plain ol’ 2509 that has one 68 pin async port on the back of the router or the 2511 which as two of these 68 pin async ports on the back of it. On each async port you can insert an octal cable which gives you eight pigtail RJ-45 ends to plug into the console port or your Cisco routers and switches.
What is the difference between a 2509 and 2511 RJ?
Pretty similar to what we had above, right? The only difference here is that the 2509 has eight RJ-45 style ports on the back into which you can install one end of a rollover cable into and then the other end would go into the back of your Cisco router or Cisco switch that you want to console into. As you can probably imagine, the 2511-RJ is the same as the 2509-RJ with RJ-45 style ports on the back. The 2511-RJ simply has 16 of these ports. The reason some people prefer the RJ models is that they can customize the length of the rollover cables to suit their individual setup.
What is an access server?
Basically what an access server is it is a glorified KVM ServSwitch for Cisco routers and Cisco switches. Just like a KVM ServSwitch, you can use hot keys to flip between devices. In this case your Cisco routers and switches.
Do I need a transceiver for AUI?
You will also need a transceiver if you want to convert the AUI port over to ethernet. This is necessary to establish a TFTP server (IOS updates / recovery), explore remote access, and for other capabilities. We always highly recommend these. They are a cheap add-on that opens up a lot of capability.
