• Use the Rx and Tx count registers in CT System/Controls to determine which
ports are carrying most traffic, and from this, based on the operational mode
selected in the DAC ES or DAC GE plug-ins screen, determine which channel
is primarily affected (requires additional bandwidth).
• If traffic requirements have changed since the DAC ES or DAC GE was first
configured, also review port priority selections. When frames are being
dropped, it is likely that traffic assigned on lowest priority ports will be most
affected.
When buffer space runs out, frames will be dropped, and a dropped-frame
counter increments to provide the ratio count of dropped frames to total frames.
No communications with the electrical or optical transceiver module. This is a
critical alarm.
Equipment malfunction.
Withdraw the DAC GE, pause, then reinsert.
Replace the DAC GE.
The DAC GE processor software is unavailable or unstable. This is a major
alarm.
There is a version mismatch in the CPU software.
DAC GE requires SW release 3.1 or later. SW must be upgraded to to 3.4 or later
to secure access to RWPR and to advanced link aggregation.
Replace the DAC GE.
