This 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:
The NEMI software consists of the following:
 |
Note NEMI software can be upgraded through Ethernet or serial ports. Flash memory can be reprogrammed through an Ethernet or serial port connection. Refer to the Cisco Metro 1500 Series Software Configuration Guide for more NEMI information. |
The modem should be connected by a cable that can transmit all the signals listed in Table C-1 to the NEMI DB9 serial connector.
| Signal | Description | Pin |
|---|---|---|
RxD | Receive data | 2 |
TxD | Transmit data | 3 |
DTR | Data terminal ready | 4 |
GND | Signal ground | 5 |
DSR | Data set ready | 6 |
RTS | Request To Send | 7 |
CTS | Clear To Send | 8 |
RI | Ring indicator | 9 |
When a WCM is installed, the data marked "Automatic Read" is automatically supplied to the NEMI. See Table C-2 through Table C-7.
