For other EPNs or the PPN, disconnect 1 end of the TDM/LAN cable
(between the D and A carriers) from the D carrier.
2. Remove the ZAHF4 TDM/LAN bus terminator from slot 21 of the D carrier.
3. Disconnect 1 end of the 8 ground straps (between the D and E carriers)
from the D carrier (see
high/critical reliability, respectively). These straps will be reconnected to the
new D carrier.
4. Disconnect the 8 ground straps from the D carrier (between the D and A
carriers or the D carrier and the enhanced fan unit—see
