Connect the SER MGT Cable
The SP serial management port is labeled SER MGT. This port is the default connection between the SP and a terminal or a computer. You must make this connection so that you can assign a static IP address to the NET MGT port later in this document.
 | Caution - Do not attach a modem to this port. |
-
On the first compute node (compute node 1), connect a Category 5 (or better)
RJ-45 cable from the SER MGT port to a terminal device or an NTS server.
When connecting a DB-9 cable, use an adapter to perform the crossovers given for each connector.
Note - Do not connect a terminal to the SER MGT port on the second compute node (compute node 2). The SER MGT port connection is necessary only for the first compute node.
-
Configure a terminal or terminal emulator with these settings:
-
9600 baud
-
8 bits
-
No parity
-
1 Stop bit
-
No handshake
A null modem configuration is needed, meaning the transmit and receive signals are reversed (crossed over) for DTE to DTE communications. You can use the supplied RJ-45 crossover adapters with a standard RJ-45 cable to achieve the null modem configuration.
Note - If you power on the compute node for the first time and do not have a terminal or terminal emulator (PC or workstation) connected to the SP SER MGT port, you will not see system messages. -
