Hot Swap Controller
The CC8-BLUES is provided with a Hot Swap controlling mechanism according to the PICMG 2.1
R2.0 specification. Hot Swap defines a process for installing and removing boards without
adversely effecting a running system. Since the CC8-BLUES was designed with cluster-computing
in mind, it was important to allow hot-plugging of the board.
The CC8-BLUES is equipped with the MIC2580 Hot Swap Controller. The MIC2580 provides for
safe and orderly insertion and removal of the CC8-BLUES from a hot-plug compliant
CompactPCI system. The MIC2580 incorporates a circuit breaker function that protects all four
supplies (+12V, +5V, +3.3V, and –12V) upon an overcurrent fault condition. Current foldback
limiting prevents large transient currents caused by plugging adapter cards into live backplanes,
such as in a CompactPCI system. A slew-rate control limits high inrush currents to all loads that
occur when power is applied to large capacitive loads. Voltage supervisory functions for all four
power supplies are provided.
