Protecting and Monitoring Hot Swappable Cards in High
Availability Systems вЂ“ Design Note 360
David Soo
Introduction
Mission critical systems, such as those used by
п¬Ѓnancial institutions and internet providers, require
high availability computing equipment. These systems
duplicate or make redundant certain functional blocks
in the system. This allows the system to operate on
the backup elements when blocks fail. High availability
systems typically place these blocks into separate cards
that can be swapped out if they fail or show signs of
trouble. This requires sophisticated monitoring to
determine when a functional block has failed and if a
back-up is operating.
Redundant Power
Often the reliability of the power distribution is improved
by providing two supplies to each card. Each supply
is fuse protected and then diode ORвЂ™ed to form one
supply rail for the card. To further increase reliability,
the voltage and current information is monitored for
power usage and usage history. This allows the system
to determine if the card is using its allotted power or …

DESIGN FEATURES Hot Swap for High Availability Systems
by David Soo Introduction
Critical computer, mass storage and
communication systems are designed
to operate with zero down time, or to
at least approach that ideal. Such
high availability systems must continue functioning even when system
upgrades and maintenance are performed. Often this requires circuit
boards be inserted into, and removed
from, a live powered system.
Hot swapping requires a power
switch to initially isolate and then
control inrush current via a controlled
ramp up of power, which prevents
any disturbance to the backplane
and adjacent circuits. Because the
Hot Swap circuit is the gateway for
all board power, it is a natural place
to monitor and collect power supply
data. Such data reveals the health
of the board and the integrity of the
power path.
With this in mind, the LTC4260 …
