CDE-200 Connector Locations
Caution
In some CDE-200 chassis the streaming interface NICs are installed in slots 4 and 5 (counting from the
left-most slot). In this hardware configuration, the Gigabit Ethernet interfaces on the motherboard are
detected as interfaces 3/0 and 4/0, and the interfaces on the NICs are detected as 1/0, 2/0, 5/0, and 6/0.
The interface numbering must be taken into consideration when configuring IP addresses and
port-channels.
Serial Console Interface Connector Pin Assignments
The serial console interface connector is a 9-pin, RS-232 D-type, DTE connector. A null modem cable
is required to connect a workstation running the Linux or Windows operating system.
