| Operating temperature |
0°C to 45°C (32°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)
NOTE:
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.). The operating temperature of the switch is 0°C to 40°C (32°F to 104°F) when it uses GE SFP optical modules with 40 km or longer transmission distances. |
| Short-term operating temperature | -5°C to +50°C (23°F to 122°F) at an altitude of 0-1800 m (0-5906 ft.)
NOTE:
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.). The equipment can operate beyond the normal operating temperature range for a short-term period, but the following conditions must be met:
The equipment may be damaged or experience unexpected exceptions if any of the preceding limits is exceeded. The equipment cannot start when the temperature is lower than 0°C (32°F). The maximum distance of optical modules used in these conditions cannot exceed 10 km. |
| Storage temperature | -40°C to +70°C (-40°F to +158°F) |
| Noise under normal temperature (27°C, sound power) | Noise-free (no fans) |
| Relative humidity | 5% to 95%, noncondensing |
| Operating altitude | 0-5000 m (0-16404 ft.) |
