DDTS # CSCdz44369
Rarely, when the active TCC2 is removed, small traffic errors of 2 to 30 ms can sometimes occur,
especially on boards with OCN ASIC. To avoid this issue, switch to the protect TCC2 before removing
the working TCC2. This issue is under investigation.

DDTS # CSCdz49928
When using KLM type fuses with specific types of fuse and alarm panels, the PWR-REDUN alarm may
not be displayed once the fuse is blown. A KLM fuse does not have a blown fuse indicator build into it.
As a result, the blown fuse detection circuitry on the FAP may continue to provide voltage on its output
despite a blown fuse.

Ethernet Polarity Detection
The TCC2 does not support polarity detection & correction on the LAN Ethernet port. This is a change
from prior common control cards, such as the TCC+. If your LAN Ethernet connection has the wrong
polarity (due to incorrect wiring on the backplane wire-wrap pins), the connection will work when using
a TCC+, but not with a TCC2. To avoid possible problems, ensure that your Ethernet cable has the
correct mapping of the backplane wire-wrap pins. For Ethernet pin mappings, consult the “DLP-A 21
Install LAN Wires on the Backplane” procedure in the user documentation.

If you are using a TCC+, the Release 4.0.x or 4.1 software will report the polarity issue (previous
releases do not), by raising the standing condition: LAN Connection Polarity Reverse Detected
(COND-LAN-POL-REV). Also, notification will appear on the fan tray LCD, which will display “BP
LAN POL. NEG.” The issue will typically be reported during the software upgrade process, but can also
be raised during a new installation when using TCC+ and Release 4.0.x or 4.1.

If this is a new installation with a TCC2 and you have the Ethernet polarity reversed, the TCC2 will not
communicate over the LAN Ethernet interface (no polarity correction will occur), and no condition will
be reported, nor will the fan tray LCD indicate an issue.
