The 5U84 chassis retains two sliding drawers, so has drawer panels that augment the operator's (ops) panel
on the left rack ear flange. Each drawer has its own set of dedicated connectors behind the midplane that allow
continuous operation, even if the drawer is extended to the fully open service position or closed with the
drawer latch engaged.
The front panel area is the primary physical user interface. Closely watch the ops and drawer panels for status.
