Figure 5 Hub Port - front view
Power Requirements
In most cases, there is no need to connect the 5V PSU supply as each port
independently takes its own power from the PS/2 keyboard connection to
the host computer.
Each Local Hub port normally takes power through the PS/2 keyboard connection to the host
computer. If any ports are used for video/serial only applications, the external 5V PSU
(supplied) should be connected to power the rack.
The green LED beside each Hub port indicates the power status of the port, and the integrity
of the CATx connection:
LED off Port not powered or keyboard PS/2 cable to Local Unit
disconnected.
LED on continuously Remote Unit not powered, CATx cable disconnected, or PC in
BIOS boot sequence.
Dual Access Hubs only: local console active.
LED flashing Remote Unit powered, data link operating correctly.
NEVER CONNECT A REMOTE UNIT’S POWER SUPPLY TO A
LOCAL HUB. THIS COULD DAMAGE THE EXTENDER SYSTEM.
Interconnect – carries video and data signals.
Connect to Interconnect port on Remote Unit
using CATx cable.
