Description
You can hot swap power supplies while the switch is operational. One power
supply is required for continuous switch operation.
Hot insertion or removal of the 8402CQ is not supported.
8402CQ can only be hot swapped with another 8402CQ using
controlled hot swap on page 29.
The 8402CQ must not be hot removed or pulled from the slot.
Important:
The slot becomes inoperable until the next reboot.

8402CQ.
For 8402CQ to operate, it must be inserted prior to the boot time. Insertion of
the 8402CQ into an empty slot while the switch is operational, results in a log
error message and the slot remains powered off until the 8402CQ is removed,
and a different ESM type is inserted.
Any ESM can be hot swapped or replaced with the same ESM type. The rest of
the configuration continues to work as original until the ESM comes online, after
which the configuration for that ESM is applied.
Any ESM except the 8424XT, 8418XTQ, 8424GS, and 8424GT can be hot
swapped or replaced with 8418XSQ, 8424XS, or 8408QQ.
The rest of the configuration continues to work as original until the replacement
ESM comes online. When the replacement ESM is online the previous
configuration for that slot is removed from the running configuration. The new
ESM type can now be configured.
The 8424XT, 8418XTQ, 8424GS, and 8424GT ESMs can only be hot swapped
or replaced with another ESM of the same type. The rest of the configuration
continues to work as original until the ESM comes online, after which the
configuration for that ESM is applied.
Upon pulling out an 8424XT, 8418XTQ, 8424GS or 8424GT ESM, and inserting
another type of ESM, the new module is powered off without any initialization
and the system must be rebooted to utilize that slot. An alarm or message is
logged to indicate that slot is powered off and requires the insertion of the
previous card type to restore the related configuration.
Upon pulling out an 8418XSQ, 8424XS, or 8408QQ and inserting an 8424XT,
8418XTQ, 8424GS, or 8424GT, the newly inserted ESM is powered off without
any initialization and the system must be rebooted to utilize that slot. An alarm
or message is logged to indicate that slot is powered off and requires the
insertion of the previous card type to restore the related configuration.
