Cisco 2600 Series Router Connection question

I need to be able to connect to a cisco 2620 router with my laptop. My laptop has a NIC card and a modem pc card. My question is can I connect to the router with a cross-over cable direct to the router or do I need to use a db-25/rj-45 adapter that connects to the db-25 port on my laptop and then connect to the router with the cross-over. Also, do I need some type of terminal software on the laptop (running win98) to be able to configure the router, or will it run the cisco IOS within the dos window just fine...

thanks for the help..
 
If you want to connect to the rouer with Ethernet, for Telnet or SSH access, then you need a crossover Ethernet cable.

If you want to attach to the "Console" port, then you'll need a "rolled" cable* and a DB9 to RJ45 adapter. If you connect to the Console (or Aux) port, you'll need some flavor of terminal emulation software, HyperTerm being the most popular, since it's included with Windows.

The 25-pin connector on your laptop is a parallel port, and it won't connect to anything on a Cisco router.

Good Luck

* Rolled cable: usually a flat eight conductor cable where the pin order is exactly reversed on one end relative to the other (1...8 --> 8...1). Category-rated cable will work but is unnecessary.
 
Thanks alot for the reply...woops..sorry..i meant db-9. Yes, I want to be able to connect directly to the console port (in the event that the network is down and I need to configure). So there's no way i could connect to the console port using a rollover direct from my NIC? I'm trying to avoid buying an adapter...also, i don't have access to the router at this moment but want to be prepared when i do which is why I'm asking now..
 
A nic is ethernet. The console port on a router is serial. no talkie-talkie.

A rolled rj45 cable and a db9-rj45 DTE adapter will do the trick. i know you can get them cheap somewhere.

<---remembers throwing out about 300 of them. 😱
 
okay...i gotcha...these are the kind of things that come to light when newbies like me practice on emulators rather than real harware...thanks for the help.

I guess for the next few weeks I am going to save all the topics related to cisco hardware for some extra reference!
Thanks

In that case, you'd probably like this link which has been helpful to me in getting up to speed on this specific router....course the cisco site in general is very useful-and FREE!
