5. Connect eight network cables from the EP8 ports marked ETHERNET to your
Ethernet network patch panel, hub, or switch.
6. Daisy-chain the ADMIN IN port on one chassis to the ADMIN OUT port on the
next chassis using the yellow daisy-chain cable provided. Connect the remaining
ADMIN OUT port to the Admin C/Port.
NOTE: If any C/Port users also use a Multi-Video Expander (MVX) with multiple
monitors, the Admin C/Port should also be equipped with an MXV and
multiple monitors. Otherwise, video from a blade equipped with an MVX
will not be viewable at the Admin C/Port.
7. Daisy-chain the SPARE IN port on one chassis to the SPARE OUT port on the
next chassis using the red daisy-chain cable provided. Connect the remaining
SPARE IN port to the Spare blade’s C/PORT port.
We suggest routing the cables down the sides of the rack to the back panel, with
the network cables on one side and the desktop cables on the other.
NOTE: Connecting a network cable to a C/Port jack on the chassis, or a C/Port cable
to a Network jack, will not damage the unit, but the system will not operate
correctly. This is a common installation error and should be one of the first
things checked when troubleshooting a problem with a system’s operation.
