Figure 5 Switch 4400 / 4400 SE — rear view 2
The appearance of the Switches shown in Figure 1 and Figure 2 differ but
the functionality is identical for both Switches.
Power Socket The Switch automatically adjusts its power setting to any supply voltage
in the range 90-260 VAC.
Redundant Power
System Socket
To protect against internal power supply failure, you can use this 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
Slots
You can use these slots to install Expansion Modules. These allow the
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.
