Operating temperature |
Operating temperature: (at an altitude below 1,800 m [5,905.51 ft.], with industrial optical transceivers installed) ● –40°C to +65°C (–40°F to +149°F) (installed in an enclosed cabinet) ● –40°C to +70°C (–40°F to +158°F) (installed in a ventilated cabinet with a minimum air velocity of 80 Line Feet Minute [LFM]) ● –40°C to +75°C (–40°F to +167°F) (installed in a fan-equipped cabinet with a minimum air velocity of 200 LFM) Note: At an altitude between 1,800 m (5,905.51 ft.) and 5,000 m (16,404.20 ft.), every time the altitude increases by 220 m (721.78 ft.), the maximum temperature decreases by 1°C (1.8°F). Storage temperature: –40°C to +85°C (–40℉ to +185℉) |

IP rating |
IP41 by default. When the IS52-shield protection enclosure is installed, the IP rating reaches IP55. Note: Without any protection enclosure, the front panel of the switch should not be installed upward to meet the IP41 protection requirements. |
IP40 Note: For bare metal servers, the front panel port should not be installed upward to meet IP40 requirements. |
