Introducing the ProCurve Series 5400zl 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 5400zl 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, laptop, or handheld device
emulating a VT-100 terminal, or on a standard VT-100 terminal.

Reset Button

This button will reset the switch when 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 ProCurve
Manager.
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

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.
