The ALARM LED indicates the presence, or absence, of an unread system
alarm(s). Unread system alarms can be read using the LCD and five-function
keypad. The possible states and descriptions of the ALARM LED are listed in
Table 3-5.
Out-of-Band Management
Out-of-band management refers to managing the system via a Local Management
(LM) connection or an SNMP-based management application which does not use
the same network connection to the chassis as “user data.”
The 9C300-1 Environmental Module provides four out-of-band management
interfaces for managing the MMAC-Plus system. These interfaces are listed
below:
• Two serial communication ports, COM1 and COM2
• One standard Cabletron EPIM interface
• Liquid Crystal Display (4 lines by 40 characters) and an associated five button
keypad
