Redundant power supply

Cold backup of uplink hybrid optical-electrical ports or electrical ports and power adapters, cold backup of uplink hybrid optical-electrical ports and electrical ports, and preferential power supply by power adapters (By default, no power adapter is provided, and the power adapter 02221024 can be used.)

Long-term operating temperature [°C(°F)]

-5°C to +45°C (23°F to 113°F) at an altitude of 0-1800 m (0-5906 ft.)

Short-term operating temperature [°C(°F)]

Not supported

Restriction on the operating temperature variation rate [°C(°F)]

When the altitude is 1800-5000 m (5905.44-16404 ft.), the highest operating temperature reduces by 1°C (1.8°F) every time the altitude increases by 220 m (721.78 ft.).

The device cannot start when the temperature is lower than 0°C (32°F).

The operating temperature of a device ranges from -5°C to +45°C (23°F to 113°F)) when the device uses the following optical modules:

- GE optical modules with a transmission distance of less than or equal to 10 km
