EMC Connectrix B Series v6.2 ED-DCX-4S-B Hardware Reference Manual
Specifications
Environmental requirements
Table 19 lists the environmental operating ranges for the
ED-DCX-4S-B. The requirements for non-operating conditions are
also provided for acceptable storage and transportation
environments.
Note: The 10° to 40° Celsius range applies to the ambient air temperature at
the air intake vents on the nonport side of the ED-DCX-4S-B.
The temperature inside the ED-DCX-4S-B can be up to 75
° Celsius during
operation. If the internal temperature range exceeds the operating ranges of
the components, the LEDs, error messages, and Fabric Watch alerts will
indicate a problem. Use the tempShow command or Fabric Watch commands
to view temperature status.
