Port Locations
on the CE7922
and the CE7900
Controller Tray
154
The CE7922 controller tray and the CE7900 controller tray have host channels that
you can attach to the hosts, and drive channels that you can attach to the drive trays.
The examples in this section show the CE7900 controller tray. The port locations are
the same for the CE7922 controller tray.
Each of the two controllers in the CE7900 controller tray might have two host

cards with four host ports on each card. This configuration is shown in the
following figure. Some CE7900 controller trays might have controllers with only
one host card each.
Controller A is inverted from controller B, which means that its host channels are

upside-down.
