3.1.4.2 Installing the Ethernet Connection
Connect a standard Category 5 network cable to the Ethernet RJ-45 port (and the other as
optional redundancy/backup). Connect the other end of the Category 5 network cables to
your IP network. The Ethernet connectors (labeled Ethernet 1 and Ethernet 2) are wired
according to Figure
3-7.
When assigning an IP address to the gateway using HTTP (under Step
1 in Section 4.2.1),
you may be required to disconnect this cable and re-cable it differently.

Note: For redundant operation it is recommended to connect each of the Ethernet
connectors to a different switch.
3.1.4.3 Connecting the RS-232 Port to Your PC
Using a standard RS-232 straight cable (not a cross-over cable) with DB-9 connectors,
connect the RS-232 port to either COM1 or COM2 RS-232 communication port on your
PC. The required connector pinout and gender are shown below in Figure
3-8.
Note that the RS-232 port is available only on the 1, 2 and 4-span configuration.
For information on establishing a serial communications link with the gateway, refer to
Section
11.2 on page 248.
