The 4xflexi supports hot swapping. Hot swapping allows you to remove, replace, and rearrange the line cards without disconnecting the system power. When the system detects that a line card is added or removed, it automatically runs diagnostic and discovery routines, and acknowledges the presence or absence of the line card.
If you remove and replace a 4xflexi with another 4xflexi, the newly installed line card receives the same provisioning as the original line card. The system resumes operation without any operator intervention.
|
Note If you are using a Cisco 6100/6130 with NI-1 system and you remove a Dual-port CAP ATU-C line card (2xCAP), a Quad-Port DMT-2 ATU-C (4xDMT-2), or a Quad-port STU-C line card (4xSDSL) and replace it with a 4xflexi, you must follow the upgrade procedure in either the Cisco 6130 with NI-1 Direct Connect Installation Guide or the Cisco 6100 with NI-1 Direct Connect Installation Guide. |
If an unprovisioned line card is installed for the first time, the system identifies it as present but unprovisioned. Instructions for provisioning the line card are found in the appropriate software guide for your chassis.
The following items are examples of recommended line card installation and replacement practices:
Any line card that is only partially connected to the backplane can disrupt system operation.

|
Note This section applies to the Cisco 6100 or Cisco 6130 with NI-1 system only. |
When the 4xflexi is reset, the system controller executes boot code that is stored in Flash memory. The boot code initializes the serial management bus (SMB). If the current image in the 4xflexi flash is not the latest image available, the system controller sends the correct image for the 4xflexi over the SMB. The image is loaded and run from Flash memory. The system controller also sends a new image if you place either a 4xflexi with a DMT image in a slot that is preprovisioned for CAP or a 4xflexi with a CAP image in a slot that is preprovisioned for DMT.
