You have migrated a
peripheral or DSU cabinet
from an SX-2000 system to a
3300 ICP system and the
Cabinet does not boot up.
Incompatible FIM modules. Before you migrate a PER/DSU to a 3300
ICP, ensure that you identify the types of
FIM modules required before migrating:
• single to single
• multi-mode (820 nm) to multi-mode
(820 nm), or
• multi-mode (1300 nm) to multi-mode
(1300 nm).
The part numbers for the supported FIM
modules are listed in the “Install and
Replace Units” chapter of the MCD
Technician’s Handbook.
LS/GS Trunks. Ensure that the programming matches the
CO trunk equipment configuration (if the
CO equipment is loop start, ensure that the
trunk circuit is programmed as loop start)
and that the system option “Interconnect
Checking for Conference Calls” is enabled
in the System Options form to prevent
“hung-up” trunks.
Check Tip and Ring polarity.
Check Tip and Ring voltages.
Insufficient DTMF receivers (not
enough for peak traffic load).
Add DTMF resources.
Fault in peripheral switch control. Swap the following cards with known
working cards:
• Peripheral switch controller card (slot 16
of a peripheral cabinet)
• Peripheral Resource card
• Control Resource card (SX-2000
MicroLIGHT systems only)
Faulty LS/GS Trunk Card,
E&M Trunk Card, or
DID/Loop-Tie Trunk Card.
Faulty external trunk equipment or
main distribution frame
connections
Fix external trunk equipment and check
main distribution frame connections.
Faulty main distribution frame and
system connections.
Check main distribution frame and system
connections.
Faulty programming. Check programming. See the System
Administration Tool online help for details.
