Slot Layout

Table 4-179 Slots on the CE8851-32CQ8DQ-P
Slot Type Slot ID Slot Direction Remarks
Power Slots PWR1, PWR2 Horizontal
  • This switch has two power module slots and supports pluggable power modules. A chassis can use one or two power modules. In particular, dual power modules provide higher reliability.
  • This switch supports 1+1 backup of power modules. When both power modules are working properly, each of them provides half of the power required for the chassis. When one power module fails, the other one provides all power required for the chassis.
  • The power modules of the devices are hot swappable.
Fan Slots FAN1 to FAN6 Horizontal
  • This switch has six fan slots in which pluggable fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability.
  • It is recommended that six fan modules be properly installed on a switch to ensure normal switch operating. The switch supports six pluggable fan modules that work in hot standby mode. 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 fan modules are hot swappable.

Ports

Port Connector Type Description Available Components
200GE/100GE/40GE QSFP56 Optical Port QSFP56

Port for inputting and outputting 200GE/100GE/40GE optical signals

1. 100GE ports can be configured as 40GE or 50GE (50GE: 2 x 25GE) ports but cannot be split into 2 x 50GE ports.

2. A 100GE port can be split into 4 x 25GE, 4 x 10GE, or 2 x 50GE (50GE: 2 x 25GE) ports. Ports 1 and 2, 3 and 4, ..., and 31 and 32 form different groups. The two ports in a group need to be split together. For example, ports 1 and 2 form a group. When port 1 is split, port 2 is also split. 200GE ports can be configured as 40GE/100GE ports and can be split into 2 x 100GE (100GE: 2 x 50GE) ports. In V300R020C00, ports 1 and 2 cannot be split, and 200GE ports cannot be split. This restriction does not apply to V300R020C10 and later versions.

NOTE:

1. Support for optical modules:

(1) In the case of port-side air intake, downlink 100GE/200GE ports support 100G-SR4/CWDM4/LR4/4WDM.

(2) In the case of port-side air exhaust, downlink 100GE/200GE ports support 100G-SR4/CWDM4.

2. Support for copper cables: When 200GE copper cables are used, contact Huawei engineers for interconnection verification.
400GE/200GE/100GE/40GE QSFP-DD optical port QSFP-DD

Port for inputting and outputting 400GE/200GE/100GE/40GE optical signals

1. 400GE ports can be used as 200GE, 100GE, and 40GE ports.

2. In V300R020C10, a 400GE port can be used as a 200GE/100GE/40GE port and can be split into 4 x 100GE (100GE: 2 x 50GE but not 4 x 25GE) ports. Other port split modes, such as 2 x 200GE/2 x 100GE/2 x 40GE/8 x 50GE/8 x 25GE/8 x 10GE/4 x 50GE/4 x 25GE/4 x 10GE, are not supported. In V300R021C10, a 400GE port can be dynamically split into 2 x 200GE ports. Currently, 2 x 200GE AOCs and 2.5 m copper cables can be used.

NOTE:

1. Support for optical modules:

(1) In the case of port-side air intake, uplink 400GE ports support 400G-SR8/SR4/DR4/FR4. When the ambient temperature ranges from 0°C to 35°C (32°F to 95°F), 400G-LR8 is supported. However, the noise of the device exceeds the threshold at room temperature.

(2) In the case of port-side air exhaust, uplink 400GE ports support 400G-SR8/SR4. However, the noise of the device exceeds the threshold at room temperature.

V300R021C10 and later versions:

40GE/100GE/200GE/400GE copper cables are supported. A 400GE port can be dynamically split into 2 x 200GE ports. 2.5 m copper cables can be used. When 200GE and 400GE copper cables are used, contact Huawei engineers for interconnection verification.

V300R020C10 and V300R021C00:

40GE/100GE/200GE/400GE copper cables are supported. After uplink ports are split, copper cables are not supported. When 200GE and 400GE copper cables are used, contact Huawei engineers for interconnection verification.

V300R020C00:

40GE/100GE copper cables are supported. After a port is split, copper cables are not supported. 200GE/400GE copper cables are not supported.

Heat Dissipation System

The cooling system of the CloudEngine 8800 series switches uses front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used.

  • Front-to-back airflow: Power modules and fan modules with front-to-back airflow are identified by . Air flows into the chassis from the power supply side and is exhausted from the port side, as shown in Figure 4-218 (using a CE6866-48S8CQ-P chassis as an example).
  • Back-to-front airflow: Power modules and fan modules with back-to-front airflow are identified by . Air flows into the chassis from the port side and is exhausted from the power supply side, as shown in Figure 4-219 (using a CE6866-48S8CQ-P chassis as an example).
    Figure 4-218 Front-to-back airflow for port-side exhaust
    Figure 4-219 Back-to-front airflow for port-side intake

The airflow direction of the power modules and fan modules required on the CloudEngine 8800 series switches depends on how the device is installed in a cabinet. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If a switch is installed with the power supply side facing the front and the port side facing the back, the switch needs to adopt fan modules and power modules with front-to-back airflow.

Power modules and fan modules using forced air cooling on a switch must have the same airflow direction. If a switch adopts power modules with back-to-front airflow, the switch must use fan modules with back-to-front airflow as well.
