9C300-1 Environmental Module Operation
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 that 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 SmartSwitch 9000 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
COM1 and COM2 Ports
The 9C300-1 Environmental Module front panel has two RJ-45 communication
ports for RS-232 serial communication to and from the SmartSwitch 9000.
Figure 3-5 illustrates a single RJ-45 communication port connector. COM1 and
COM2 can be configured to run the Serial Line Internet Protocol (SLIP), Point-to-
Point Protocol (PPP), Local Management via a terminal or modem connection, or
monitor an American Power Conversion Smart UPS. Refer to the Local
Management Manual for detailed information on configuring the COM1 or
COM2 port.
