Switch Hardware Features
Clear Button
This button is used for these purposes:
■ Deleting Passwords - When pressed by itself for at least three seconds,
the 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, any configuration changes you may
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, see “Restoring the Factory Default Configuration”
in chapter 4, “Troubleshooting” of this manual.
Switch Features
The features of the ProCurve 1810G-24 Switch include:
■ 24 auto-sensing 10/100/1000Base-T RJ-45 ports.
■ plug-and-play networking—all ports are enabled—just connect the
network cables to active network devices and your switched network is
operational.
■ IEEE 802.3ab Auto MDI /MDI-X on all twisted-pair ports, meaning that all
connections can be made using straight-through twisted-pair cables.
Cross-over cables are not required, although they will also work. The pin
operation of each port is automatically adjusted for the attached device:
if the switch detects that a 10/100 Mbps switch or hub is connected to the
port, it configures the port as MDI; if the switch detects that a 10/100 Mbps
end-node device is connected to the port, it configures the port as MDI-X.
■ a “Green Mode” option that keeps LEDs turned off except for when the
Mode Select button is pressed.
■ an automatic low-power mode for ports when a link is not present.
■ automatic learning of the network addresses in each switch’s 8000-
address forwarding table.
■ automatically negotiated full-duplex operation for all 10/100/1000Base-T
RJ-45 ports when connected to other auto-negotiating devices
■ the mini-GBIC ports always operate at full duplex.
