NEMI Software SpecificationsNEMI Software Specifications
The appendix lists the hardware and software specifications of the NEMI, settings for an external modem, and the SNMP protocols for the wavelength channel modules (WCMs). This appendix includes the following sections:
NEMI Software
The NEMI software consists of the following:
- Linux 2.0.35
- SNMP agent
- Telnet server
- FTP server
- NTP server
 |
Note NEMI software can be upgraded through Ethernet or serial ports. Flash memory can be reprogrammed through an Ethernet or serial port connection. See the "Transferri ng a System Update" section. |
SNMP Features of WCMs
When a WCM is installed, the data marked "Automatic Read" is automatically supplied to the NEMI. See Table C-1 through Table C-6.
