Console Port; Reset Button; Clear Button - HP J4865A Installation And Getting Started Manual

Introducing the HP ProCurve Series 4100gl Switches
Front of the Switch

Console Port

This port is used to connect a console to the switch by using the serial cable
supplied with the switch. This connection is described under "Connecting a
Console to the Switch" in chapter 2, "Installing the Series 4100gl Switches".
The console is a full-featured interface that can be used to configure, monitor,
and troubleshoot the switch. It can be run on a PC emulating a VT-100 terminal,
or on a standard VT-100 terminal.

Reset Button

This button is used to reset the switch while it is powered on. This action clears
any temporary error conditions that may have occurred, executes the switch
self test, and resets all network activity counters to zero. The counters are
displayed in the switch console interface, the switch web browser interface,
and through SNMP network management applications, such as HP ProCurve
Manager for Hubs & Switches.
Press the Reset button also after changing the module type that is installed in
any of the switch module slots while the switch is powered on. In this case,
the switch must be reset to initialize the new module type. See "Hot Swapping
Switch Modules" on

Clear Button

This button is used for the following purposes:
1-8
page 2-21.
Deleting Passwords - When pressed by itself for at least one second, the
Clear button deletes any switch console access passwords that you may
have configured. Use this feature if you have misplaced the password and
need console access.
This button is provided for your convenience, but its presence means
that if you are concerned with the security of the switch configuration
and operation, you should make sure the switch is installed in a secure
location, such as a locked wiring closet.
Restoring Factory Default Configuration - When pressed with the
Reset button in a specific pattern, the Clear button clears any configura­
tion changes you may have made through the switch console, the web
browser interface, or SNMP management, and restores the factory default
configuration to the switch. For the specific method to restore the factory
default configuration, see "Restoring the Factory Default Configuration"
in chapter 4, "Troubleshooting" of this manual.
