How is the S12700 grounded


The chassis of an S12704, S12708 or S12712 has a ground screw on the lower left part of the rear.
Ensure correct grounding to guarantee the normal operation of the S12700.

What is the temperature of the S12700 in different situations
The temperature range of the S12700 is as follows: Operating temperature: 0°C to 45°C Storage temperature: -40°C to +70°C You can run the display temperature command to view the temperature of the S12700 card. If no alarm is generated, the device is working normally and the temperature is within the allowed range. NOTE: The set transceiver temperature threshold command sets the temperature threshold for adjusting the fan speed. When the temperature of an optical module exceeds the upper threshold, the fan speed is increased. When the temperature of an optical module falls below the lower threshold, the fan speed is reduced. The display transceiver temperature threshold command displays the upper and lower temperature thresholds for adjusting the fan speed.

S12700 SFU clustering
The S12700 uses a hardware architecture that separates the switching plane from the control plane. It has independent SFUs, and the CSS card is installed on the SFU. Packet forwarding is not affected when the S12700 has no MPU installed. This architecture allows two S12700s to set up a CSS with no MPU installed on the standby switch. 1+N backup of MPUs enables a CSS to run stably as long as one MPU of any chassis in the CSS is working normally.

How can I ground the camera
Camera grounding includes video grounding and power grounding. Video grounding: Terminals such as DVR or matrix are used for indirect grounding. It is recommended that video grounding be completed on the local camera if videos are transferred through a video transfer device such as an optical transceiver. Power grounding: The ground terminals of the AC and DC power supplies need to be grounded when a centralized power supply mode is used, for example, switch-mode power supply (SMPS). Grounding standards: For the insulated copper-conductor cables used as ground cables as well as the power cables, their minimum cross-sectional area must be 6 square millimeters, minimum buried depth must be 0.5 m, and ground resistance must be smaller than 4 ohms.
