Keyswitch
This is a standard CPU keyswitch, discussed on page 3-15.
Front Panel Connectors
The full functionality of these ports is detailed in GFK-1541, TCP/IP Ethernet Communications for
the Series 90 PLC User's Manual.
Shield Ground Connection Tab
This tab is used to make the module's shield ground connection. A wire with the applicable
terminal ends is supplied with the module for this purpose. Please see the section "CPU363, 364,
and 374 Shield Grounding" in Chapter 2 ("Installation") for details.

Station Mgr - This connector is used to connect a terminal or terminal emulator to access the
Station Manager software on the Ethernet Interface. This RJ-11 connector has the same pinout
as Port 1 of the CPUs 351, 352, 353, and 364 shown in Table 5-5. The IC693CBL316 cable
can be used to access this port. See Chapter 10 for a data sheet on this cable.
10/100 Ethernet (Port 1 and Port 2) – these two 8-pin, RJ-45 ports provide a direct
connection to an Ethernet network via an embedded network switch.
The two Ethernet ports are 10-BASE-T/100-BASE-Tx Autonegotiating Full-Duplex ports,
which provide direct connection to one or two 10-BASE-T/100-BASE-TX cat 5 (twisted pair)
Ethernet LAN cables. Cables may be shielded or unshielded, and direct or cross-over. Please
note that the ports are connected to an embedded switch. There is not a separate IP address for
each port.
The LINK/ACT LED on each port goes on when a network link is established and blinks when
data is being transferred through the port. The 100Mbps LED goes on if the network link has
been established at 100 MBPS and goes off if the network link has been established at
10Mbps.
The CPU and Ethernet Interface firmware, which is stored in Flash memory, is loaded through
the serial port connector on the PLC Power Supply using a personal computer that has been
equipped with the loader and CPU firmware software.
