the rate that you want to set.

* Note: Do not use the 20%, 40%, or 80% options of the Web

Agent or CLI.

Frames Transmitted with Cyclic Redundancy Check (CRC)
Errors

Problem:

For certain revisions of the Cajun P550R/P580/P880/P882 switch
12- and 20-port module (Model M5520-100TX, module Type 9,
revision level A or B and M5512-100TX, Revision A), a temperature
sensitivity problem has been found when operating at 10 Mbps. This
sensitivity results in the port transmitting frames with CRC errors.
These frames, since they have CRC errors, are then dropped by the
receiving station.

Workaround:

The following legacy-cli command allows you to implement a new
configuration to disable the power saving mode of the Phy chip. This
has the same effect as moving the port’s operational temperature
past the problem range. The new configuration is saved only in
NVRAM:

> port set DisablePowerSave on

* Note: Except for this command, the Legacy-CLI is not

supported by the Cajun Switch.
