FusionServer 5288 V7 Server
Technical White Paper
Symptom
Improper register settings
cause errors or failures in
reading parameters or
diagnostic information.
Optical modules bring
electromagnetic
interference to nearby
devices.
Services are interrupted
when an optical module is
operating under
overtemperature.
Optical modules cannot
work properly when the
temperature change rate
exceeds the normal range
without adapting to the heat
dissipation policy of the
server.

Cause
Some optical modules that have not been tested for
compatibility have improper register values on page
A0, which can cause errors or failures when the
data bus attempts to read parameters or diagnostic
information.
Some optical modules that have not been tested for
compatibility are not designed in compliance with
EMC standards and have low anti-interference
capability. Additionally, they bring electromagnetic
interference to nearby devices.
The operating temperature ranges of optical
modules that have not been tested for compatibility
cannot meet service requirements. When they are
used under a relatively high temperature, the optical
power decreases, resulting in service interruption.
Some optical modules that are not tested for
compatibility have poor heat dissipation. Since they
are not adapted to the heat dissipation policy of the
server, abnormally high temperatures may occur
continuously after they are running for a period of
time. As a result, the optical modules cannot work
properly.
