Operation
Page 3-2
The NET-PATHm can operate for two hours after primary power fails. Power loss that
exceeds the internal UPS capacity results in the NET-PATHm performing an orderly
shutdown. Data stored in Flash memory is unaffected by a power loss. Data stored in
SDRAM is lost when the NET-PATHm shuts down after the UPS battery depletes.
When the power restores, the processor checks the memory and reboots the unit. This
initializes all hardware but does not affect the data stored in Flash memory. This
includes the user database. You can program internal NET-PATHm fixed events to
signal power loss, power return, or an orderly shutdown. These fixed events allow the
user to intervene and retrieve data stored in SDRAM, preventing data loss.

Command
Mode
You can communicate with the NET-PATHm through the internal modem, a serial
port, or via Telnet. All modes offer access to the NET-PATHm Command Line
Interface that allows a technician to examine status and control several NET-PATHm
functions.
Use any unassigned port to establish communication with the NET-PATHm
Command Line Interface. You must enter a user name and password to gain access.
Your system administrator can provide you with a login and password. To access the
command line on the NET-PATHm, use one of the following methods:
• Use a third-party terminal program to connect (via null modem cable) to a serial
port on the NET-PATHm.
• Use a third-party terminal program to connect to the NET-PATHm via modem.
• Use a third-party telnet client to connect to the NET-PATHm via the network.
• Use IRISnGEN Remote Agent Manager to establish a dial-up connection and go
transparent to the NET-PATHm.
• Use IRISnGEN Remote Agent Manager to establish a Telnet connection and go
transparent to the NET-PATHm.
Connecting to
the NET-PATHm
Serial Port
To connect to the NET-PATHm serial port
1
Use a null modem cable to connect a serial port on the NET-PATHm to a serial
port on your laptop or PC.
2
Using a terminal program such as ProComm or HyperTerminal, connect the
COM port you are using on your computer to the NET-PATHm. Verify that the
port settings for the baud rate, parity, data bits, and stop bits correspond to the
port settings on the NET-PATHm. Default settings for the NET-PATHm ports are
9600, 8-N-1.
3 Type login and then press the Enter key.
The User name: prompt displays.
4 Type your user name and then press the Enter key.

5 Type your password and then press the Enter key.
6 If the user name and password you enter are correct, the NET-PATH> prompt
displays, indicating a successful logon to the NET-PATHm.
Note
You cannot use a NET-PATHm port for local
communications if that port is assigned to monitor
a host device!
