On a TPS TX Series or TXE 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 identical I/O module without interruption to the TPS device.
 |
NoteHot-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.
- The second slot of the 5500TX device supports only the first four segments of a 6-segment I/O module.
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.
When the device is managed by the SMS, a delay of up to 1 minute can occur before
the SMS recognizes the changed I/O module.
|
NoteWhen you insert a bypass I/O module, the
bypass I/O module always starts up in bypass mode. A bypass I/O module remains
in
bypass mode until you remove it from bypass mode. To change the module from bypass
mode to normal mode using the SMS, click the device and select Device
Configuration -> HA (High Availability) -> Zero Power HA. To
configure this using the device CLI, refer to the respective documentation.
Rebooting the TPS does not change the bypass mode of the bypass I/O module.
