Is there an easy way to be sure I have the right TDM/LAN bus cables?
For a multi-carrier cabinet, look for a yellow or a blue label on the cable. Older versions of the
TDM/LAN Bus cables WP-91112 (L1 and L2) and WP-91716 (L1 and L2) had white labels. The
correct cables WP-91716 (L6 and L7) originally had blue labels, and currently have yellow labels.

Which AC power supplies are compatible with port carriers in upgrades?
* Not completed drawing.
NOTE:
Do Not Use: Old power supplies (631AR, 631BR, 631WA, and 631WB) are not to be used
in this carrier because if they are mixed and matched with new power supplies, (631DA
and 631DB) in the this carrier the old power supply shorts out the new power supply that
is installed at the other end of the carrier. In a hot plug-in situation this can cause arcing
that damages backplane pins and power supply connector contacts.
