I/O module replacement
On a TPS TX Series device, hot swapping allows you to add, remove, or replace an I/O module without
shutting down the device. When the device is turned on, you can hot swap an I/O module without
interruption to the TPS device.
Note: Hot-swapping I/O modules during system initialization is not supported.
When you hot swap an I/O module, keep the following points in mind:
• The module port configuration is always reset.
• The module segment configuration, including link-down synchronization, Intrinsic HA, and inspection
bypass, is always preserved.
When the device is turned off, cold swapping allows you to add, remove, or replace an I/O module as you
would when you hot swap. However, when you cold swap an I/O module, if the replacement module type is
the same, the module port configuration is preserved.
