Environmental requirements
Ensure that the environmental requirements are met. Refer to the Brocade VDX 8770 Switch Technical
Specifications on page 95.
CAUTION
Do not install the device in an environment where the operating ambient temperature might
exceed 40°C (104°F).
NOTE
The 0° to 40°C (32° to 104°F) range applies to the ambient air temperature at the air intake vents on the
port side of the device.The temperature inside the chassis can reach up to 90°C (194°F) for some
modules during operation. Brocade recommends that the internal temperature not exceed 75°C
(167°F). Cooling policy is based on a combination of ambient temperature and measured temperature
on the modules. Various combinations will result in an increase in fan speed to create more cooling in
the device. If a component approaches a critical temperature that will trigger a module shutdown, there
will be a WARNING message in the RASlog, followed by a CRITICAL message saying that the module
will shut down in two minutes.Use the show environment command to view temperature status.
Chassis slots
Chassis slots are coded and numbered to differentiate between management module slots, switch
fabric module slots, and line card slots. Management modules (MMs) must be installed only in slots M1
and M2. switch fabric modules (SFMs) must be installed only in slots S1 through S6. There must be at
least one switch fabric module installed in either slot S3 or slot S4. The line card slots, L1 through L8,
can be filled with any supported line cards. Unused slots must be filled with the correct filler panels to
maintain adequate cooling.
