- The DC chassis and AC & high-voltage DC chassis have similar appearances and structures except that they use DC and AC & high-voltage DC power modules (PMs) and power entry modules (PEMs) respectively. The figures show the appearance of an AC & high-voltage DC chassis as an example.
- Figures in the document are for reference only, and the actual appearance of the devices may vary depending on the exact device model.
Components
In the CloudEngine 16816 chassis, MPUs and LPUs are installed horizontally in the front of the chassis, and SFUs are installed vertically at the rear of the chassis, as shown in Figure 3-14.

Table 3-18 Slots on the CloudEngine 16816
| Slot Type | Slot ID | Slot Direction | Remarks |
|---|---|---|---|
| LPU slot | Slots 1 to 16 | The top of the board faces upwards | Different types of LPUs can be installed in the same chassis. |
| MPU slot | Slots 17 and 18 | The top of the board faces upwards | Two MPUs work in active/standby mode for 1:1 hot standby. By default, the MPU with a smaller slot ID is the active MPU, and the MPU with a larger slot ID is the standby MPU. |
| SFU slot | Slots 1 to 9 (Slots 1, 2, and 9 cannot be used.) | The right side of the board faces upwards | SFUs work in load balancing and redundancy mode. SFUs in the same chassis must be the same model. That is, SFUs of different models cannot be installed in the same chassis. |
| PM slot | Slots 1 to 20 | The indicator light end upwards | PMs are plug-and-play. |
| Fan module slot | Slots 1 to 3 | The indicator light end upwards | At the normal temperature range, the system can operate properly for a short time after a single fan module fails. You are advised to replace the faulty fan module immediately. |
The SFU reduction mode is configured using the set sfu reduced-mode command. In this mode, only slots 3, 5, 6, and 8 are available and slots 1, 2, 4, 7, and 9 are unavailable. In V200R021C10 and later versions, after SFUs are installed in slots 1, 2, 4, 7, and 9, the SFUs will be powered off and alarms will be reported to the NMS.
By default, SFUs in slots 3 to 8 are available, that is, the set sfu reduced-mode command is not run. In V200R021C10 and later versions, after SFUs are installed in slots 1, 2, and 9, the SFUs will be powered off and alarms will be reported to the NMS.

- Temperature and humidity are measured at 1.5 m (4.92 ft.) above the floor and 0.4 m (1.31 ft.) in front of the rack. There should be no protection board in the front or rear of the rack.
- If the PMs use a 110 V AC power source, follow these suggestions:
- Use double live wires. In this case, the output power of a PM is 3000 W.
- If only one live wire is used, the output power of a PM is 1500 W. In this case, it is recommended that you use more PMs or change the PM backup mode to increase the output power.
- For details about power consumption calculation, see the Hardware Configuration Tool.
