• If the Full Duplex (FDx) indicator LED is lit, the port LEDs light for those ports that are
operating in full-duplex mode.
• If the Speed (Spd) indicator LED is lit, the port LEDs behave as follows to indicate the
connection speed for the port:
— OFF = 10 Mb/s
— Flashing = 100 Mb/s (the flashing behavior is a repeated on/off cycle once every 0.5 s)
— ON = 1000 Mb/s
2.4.1.3 Reset Button
The reset button is used to reset the switch while it is turned on. This action clears any temporary
error conditions that occurred and executes the switch self-test.
2.4.1.4 Clear Button
The clear button is used for the following purposes:
• Deleting passwords — When pressed by itself for at least 1 second, the button deletes any
switch console access passwords that you 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 must 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, any configuration changes you have made through the switch console, the Web
browser interface, and SNMP management are removed, and the factory default configuration
is restored to the switch. For the specific method to restore the factory default configuration,
refer to the HP ProCurve Switch 2650 Installation and Getting Started Guide.
2.4.1.5 Back Side of HP ProCurve Switch 2626
The ProCurve Switch (Figure 2-13 “HP ProCurve Switch Rear View”) has a power connector,
but does not have a power switch. It is powered on when connected to an active AC power
source. The switch automatically adjusts to any voltage between 100 volts and 240 volts (50–60
Hz). No voltage range settings are required.
The console port on the back of the ProCurve Switch 2626 is used to connect the switch to a
console (laptop of PC VT100 terminal emulator) by way of a serial cable.
