Removing and Replacing an Impedance Panel
Empty slots in the chassis must be covered by impedance panels. Panels must be ordered
separately. See Impedance Panels on page 43 for more information.
If you need to install a component in a slot which has an impedance panel, remove the panel
only when you are ready to install a component in its place.
An impedance panel slides into a slot using the chassis slot guides in the same way as the
corresponding component. MDA and IOM impedance panels have captive screws to secure
the panel. PSU impedance panels have a latch lock that operates like the latch lock on the PSU
components.
