Hot Swapping

Hot Swapping is the installation or removal of a component (such as a PIC)
without powering down or restarting the switch or router.
The following PICs can be hot swapped only if they are to be installed or
removed from an AR040 NSM, and the AR040 is installed in a switch or router
running Software Release 2.3.1 or later.
• AT-AR021 (S) BRI- S/T
• AT-AR021 (U) BRI-U
• AT-AR022 ETH
• AT-AR023 SYN
• AT-AR026 4ETH
The following PICs cannot be hot swapped.
• AT-AR020 PRI E1/T1
• AT-AR024 ASYN4
• AT-AR027 VoIP-FXS
These PICs, PICs installed directly into routers (that is, PICs not installed in an
AR040 NSM), or PICs installed in any device running Software Release 2.2.3 or
earlier must be installed or removed using the Standard Method (as outlined
below).
