Backplane Links and Bus Connections
•
A SwitchBlade chassis contains two controller bays each capable of
housing a switch controller card. See “Switching Performance and
Characteristics” on page 10 for more information.
•
33 MHz 64 bit PCI routing and control bus links all switch controller
and line card bays. This bus provides a high performance
communication channel between switch controller CPUs, and also
allows high speed routing between line cards that have WAN
interfaces.
Earth/Ground Point
•
An earth/ground point is provided on the chassis’s rear panel. This
point can be used to bond the chassis to earth/ground. Even if this point
is used, earth/ground leads of AC and DC power supplies must still be
connected.

For guidelines on how many PSUs are required for a particular configuration,
see “How Many PSUs do You Need?” on page 33.
