Alarms
Note
Alarms
The switch has four alarm inputs and one alarm output.
Alarm Input
The alarm input is a dry-contact alarm port. You can connect up to four alarm inputs from devices, such as a
door, a temperature gauge, or a fire alarm, to the alarm port. You can use the CLI to set the alarm severity to
minor, or major. An alarm generates a system message and turns on an LED. See the ??? for the LED
descriptions.
Alarm Output
The alarm output can be configured as a major alarm. Output alarms often control an external alarm, such as
a bell or a light. To connect an external alarm device to the relay, you connect two relay contact wires to
complete the electrical circuit. See for information on the alarm pinouts. see the
Mini USB Port
Note
Figure 2: USB Mini-Type B Port
The configurable inactivity timeout reactivates the RJ-45 console port if the USB console port is activated,
but no input activity occurs on it for a specified time period. When the USB console port deactivates due to
a timeout, you can restore its operation by disconnecting and reconnecting the USB cable. For information
on using the CLI to configure the USB console interface, see the switch software guide.
SD Flash Memory Card
The switch supports a flash memory card that makes it possible to replace a failed switch without reconfiguring
the new switch. The slot for the flash memory card is on the front of the switch. The flash card is hot swappable
and can be accessed on the front panel in non hazardous locations only. A cover protects the flash card and
holds the card firmly in place. The cover is hinged and closed with a captive screw. This prevents the card
from coming loose and protects against shock and vibration.
For more information on inserting and removing the flash memory card, see

The output of the PoE circuit has been evaluated as a Limited Power Source (LPS) per IEC 60950-1.
The 5-pin mini-Type B connectors resemble the 4-pin mini-Type B connectors. They are not compatible. Use
only the 5-pin mini-Type B.
