The console port allows you to connect a terminal and perform remote or
local out-of-band management. The console port uses a standard null
modem cable and is set to auto-baud (up to a maximum of 19200 baud),
8 data bits, no parity and 1 stop bit.
You can use this slot to install an Expansion Module. Contact your
supplier for further information on the range of Expansion Modules
supported by your Switch.
WARNING: When an Expansion Module is not installed, ensure the
blanking plate is fitted by tightening all screws with a suitable tool.
