2.8 Acknowledging / selecting alarms
To acknowledge an alarm, select it from any Alarm window, then use the
Acknowledge command from the Alarms menu, the Alarms Speed
menu, or the toolbar button. As a short cut, you can simply double-click
on the alarm. You can also select multiple alarms.
Once acknowledged, the alarm’s entry in the Unacknowledged Alarms
window will be removed, and the relevant symbols in the Alarm Log
windows will stop flashing. When all alarms for a certain device have
been acknowledged, the Alarm symbol next to the device in the Network
Inspector Window will stop flashing. When all alarms for the whole
network have been acknowledged, the Alarm Panel in the toolbar will
stop flashing.

wish to select/deselect.
2.9 Ports, Links and Terminals
PCNC can receive alert messages either through serial COM ports or
from a TCP/IP network via a Network Interface Card. To receive
messages over TCP/IP you will need to install the SNMP extensions
which are an optional feature of PCNC. Note, however, that PCNC
cannot communicate directly with your NIC. To use PCNC’s SNMP Link,
you need to install the Chameleon
package from NetManage
Inc.
PCNC communicates with the physical network using software modules
called Links. The Control Link is connected to local Cabletron devices.
The Remote Link is connected to a KBU that can receive alerts from
off-site KBUs via the ISDN network. The Auxiliary Link is used to
connect to non-Cabletron devices which do not generate alert messages
