Chapter 4 Manage the Switch via the Device Manager Web Interface
Use SNMP Management Applications
You can use SNMP management applications such as IntraVue or HP OpenView
to configure and manage the switch.
Refer to SNMP on page 111 for more
information.
Configure Alarm Settings
The switch software monitors conditions on a per port or a global basis. If the
conditions do not match the set parameters, an alarm or a system message is
triggered. By default, the switch sends the system messages to a logging facility.
You can configure the switch to send SNMP traps to an SNMP server. You also
can configure the switch to trigger an external alarm device by using the two
independent alarm relays.
Alarm Relay Settings
You can configure the switch to trigger an external alarm device. The switch
supports two alarm inputs and one alarm output. The switch software is
configured to detect faults which are used to energize the relay coil and change
the state on both of the relay contacts. Normally open contacts close and
normally closed contacts open.
To configure alarm relay settings, from the Configure menu, choose
Alarm Settings.
On the Alarm Relay Setup tab, click one of these options for each type of alarm
relay:
• Normally Opened—The normal condition is that no current flows
through the contact. The alarm is generated when current flows.
• Normally Closed—The normal condition has current flowing through the
contact. The alarm is generated when the current stops flowing.
