Global Alarms
To configure global alarms, also known as facility alarms, from the Configure
menu, choose Alarm Settings and click the Global tab.
Field Description
FCS Hysteresis (1-10) The frame check sequence (FCS) error hysteresis threshold is used to determine when an alarm condition is cleared. This value is
expressed as a percentage of fluctuation from the FCS bit error rate. The default setting is 8%.
You can adjust the percentage to prevent toggling the alarm condition when the FCS bit error rate fluctuates near the configured
bit error rate. Valid percentages for global settings are 1…10. This setting also can be configured on an individual port by
clicking the Port tab.
Alarm Name These types of alarms can be enabled or disabled:
• Dual Power Supply—The switch monitors DC power supply levels. If the system is configured to operate in a dual power
mode, an alarm is triggered if a power supply fails or is missing. The alarm is automatically cleared when the power supplies
are present or working. You can configure the power supply alarm to be connected to the hardware relays.
• Temperature-Primary—An alarm is triggered when the system temperature is higher or lower than the configured
thresholds. By default, the primary temperature alarm is associated with the major relay.
• Temperature-Secondary—An alarm is triggered when the system temperature is higher or lower than the configured
thresholds.
• License-File-Corrupt—An alarm is triggered when the license file is corrupt.
DM Alarms Alarm information appears on the dashboard of the Device Manager Web interface.
SNMP Trap Alarm traps will be sent to an SNMP server, if SNMP is enabled on the Configure > Security > SNMP window.
HW Relay The switch's alarm relay is triggered, sending a fault signal to a connected external alarm device, such as a bell, light, or other
signaling device that you have configured.
Syslog Alarm traps are recorded in the syslog. You can view the syslog on the Monitor > Syslog window.
Thresholds (MAX) in °C The maximum temperature threshold for the corresponding Temperature-Primary or Temperature-Secondary alarm, if enabled.
Thresholds (MIN) in °C The minimum temperature threshold for the corresponding Temperature-Primary or Temperature-Secondary alarm, if enabled.
