Optional USB Extender
You can plug the keyboard and mouse directly into the USB connectors of a compute
module (see “Connecting a Keyboard and Mouse” on page 19), or you can use an
optional USB extender that allows you to place the keyboard and mouse up to 328.68 feet
(100 m) from the compute module, see Figure 2-16 on page 58.
Note: The local extender (LEX) receives AC power from the system power source or
power distribution strip (PDS) in the rack. A 6-ft. (1.82-m) adapter cable connects the
extender’s power adapter to the PDU. The REX requires AC power from a source within
a 6-ft. (1.82-m) range from the keyboard/mouse connection point.
