5-2 Netra CT Server Service Manual • February 2007
5.1 Understanding Hot-Swap
Certain FRUs in the Netra CT server are hot-swappable (see Section 1.3.1, “Hot-
Swappable FRUs” on page 1-4 ). Hot-swap, a key feature of the PICMG standard,
means that a CompactPCI board that meets the PICMG standard can be reliably
inserted into or extracted from a powered and operating CompactPCI platform
without affecting the other functions of the platform.
The Netra CT system hot-swap modes are listed in
TABLE 5-1
.
The Netra CT system is configured for full hot-swap by default. You can change the
mode of the slot for the CPU boards and I/O boards to basic or full hot-swap using
the
cfgadm(1M)
command. You might want to change the hot-swap state of a slot to
basic, for example, if you need to insert or remove a third-party I/O board that does
not have full hot-swap support.
Note that whenever you reboot or power your server on and off, hot-swap reverts
back to the default full hot-swap state for all I/O slots.
TABLE 5-1
Netra CT System Hot-Swap Modes
Type of Hot-Swap Description
Basic The hardware connection/disconnection process is performed
automatically by the hardware, while the software connection
process requires user assistance through the
cfgadm (1M
)
command.
Full Both the hardware and the software connection process are
performed automatically.
High Availability High-availability hot-swap provides the ability to control the
hardware connection process. This provides a higher degree of
control than just indicating insertion and extraction of a board. The
hardware connection process is controlled by software on high-
availability systems, such as the Netra CT server.
