ensure that the bare copper wire has been cleaned and antioxidant is applied to the bare wire. In
addition, anti-rotation devices or lock washers must be used with all screw connections for the
grounding wire.
Environmental requirements
DANGER
Do not install the router in an environment where the operating ambient temperature might
exceed 40°C (104°F).
Table 5 lists the environmental operating ranges for the Brocade VDX 8770-4. The requirements for
non-operating conditions are also provided for acceptable storage and transportation
environments.
NOTE
The 0 ° to 40 ° C (32 ° to 104 ° F) range applies to the ambient air temperature at the air intake vents
on the left side (as you face the port side) and port side of the Brocade VDX 8770-4.
The temperature inside the Brocade VDX 8770-4 can be 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
switch.
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.
