Redundant power supply | 1+1 Pluggable AC and DC power modules can be used together in the same
switch, but power modules that use natural heat dissipation and
power modules that use air cooling cannot be used together. |
Long-term operating temperature [°C(°F)] | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5905.44
ft.) |
Restriction on the operating temperature variation rate [°C(°F)] | When the altitude is 1800-5000 m (5906-16404 ft.), the highest
operating temperature reduces by 1°C (1.8°F) every time the
altitude increases by 220 m (722 ft.). Devices cannot start when the temperature is lower than 0°C (32°F). The operating temperature of the switch is -5°C to +45°C (23°F to
113°F) when 10GE SFP+ optical modules with 40 km or longer
transmission distances are used. |
