Functional Notes
The current SHDSL NIM card (1200867L1) supports two code images commonly referred to as the “active”
image and the “inactive” image. When a firmware upgrade is performed on the card (through the copy
<filename> interface shdsl x/y Enable mode command), the new firmware is placed in the “inactive”
image space. This new code will not be executed until the boot alternate-image command is issued.
When the user does this, the NIM will reboot (taking the current line down) with the new code. At this point,
the old code becomes the “inactive” image and the new recently updated code becomes the “active”
image.
