Power Socket

The Switch automatically adjusts its power setting to any supply voltage
in the range 90-260 VAC.
Redundant Power To protect against internal power supply failure, you can use this socket
System Socket to connect a Switch 4400 to a SuperStack 3 Advanced Redundant Power
System (RPS). See "Connecting a Redundant Power System" on page 27.

Console Port

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, 8 data bits, no parity and 1 stop
bit.
Expansion Module You can use these slots to install Expansion Modules. These allow the
Slots Switch to support various forms of connection and add extra functionality
to your Switch. Contact your supplier for more information.
WARNING: When an Expansion Module is not installed, ensure the
blanking plate is fitted by tightening all screws with a suitable tool.
