I have a new switch that I want to configure.  It is an HP E2620-24.  What application on Windows Server 2008 would I use to access the switch and how is it done?  Thanks.

Normally you would use a terminal emulator for that like putty: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html

Don't use hyperterm, It's a mess ;)

8. (Optional) Connect a Console to the Switch
The E2620 Switches have a full-featured console interface for performing
switch management tasks including the following:
¦ monitor switch and port status and observe network activity statistics
¦ modify the switch’s configuration to optimize switch performance,
enhance network traffic control, and improve network security
¦ read the event log and access diagnostic tools to help in troubleshooting
¦ download new software to the switch
¦ add passwords to control access to the switch from the console, web
browser interface, and network management stations
The console can be accessed through these methods:
¦ Out-of-band:The E2620 Switches come with a serialcable for connecting
a PC or VT-100 terminal, to be used as a console, directly to the console
port of the switch.
¦ In-Band: Access the console using Telnet from a PC or UNIX station on
the network, and a VT-100 terminal emulator. This method requires that
the switch is configured an IP newtork address and subnet mask (for
example, manually through the console port or automatically through
DHCP/Bootp). For more information on IP addressing and on starting a
Telnet session, see chapter 3, “Configuring the Switch”. Also, see the
Management and Configuration Guide for your switch at

I am trying to setup a Telnet session with the switch.  I have the cable they provided plugged into the serial port on the PC and I am plugged into the console jack on the switch.  When I attempt to access the switch from the Telnet session it tells me that COM1 cannot be accessed thru port 23 (default).  It states "could not open connection to the host, on port 23.  Connection failed.  I have added Telnet to the Windows firewall and I am still not able to connect.  Any ideas?  Thanks!

Ok, for a console session use the option 'serial' (in putty).
