2.1.4.1 Hot Swapping Cards
Hot swapping allows you to remove and replace cards without disconnecting the system power. The
Cisco 6260 chassis supports hot swapping for the following cards:
•
•
•
•
•
•
•
When the system detects that you have added or removed a line card, it automatically runs diagnostic
and discovery routines and acknowledges the presence or absence of the line card. If you remove and
replace a line card with one of the same type, the newly installed line card receives the same provisioning
as the original card. The system resumes operation without any operator intervention.
Hot swapping line cards interrupts service for the subscribers assigned to that line card.
Note
The Cisco 6260 also supports hot swapping for the DS3/2DS3 and OC-3c/OC-3c NI-2 cards. Hot
swapping active NI-2 cards interrupts service for the entire system until the NI-2 card is replaced or until
a redundant NI-2 takes over system operations. However, you can hot swap standby NI-2 cards without
interrupting service.
2.1.4.2 Hot Swapping I/O Modules
Hot swapping allows you to remove and replace an I/O module without disconnecting the system power.
The Cisco 6260 chassis supports hot swapping for the I/O module, but removing the I/O module
interrupts the service for the entire system until it is replaced.
The I/O module must be installed and replaced by a trained technician only.
