When using one power supply I need to order two or one FAN-40EA?
When using two power supplies do I need to order two PAC-600 WA, two FAN-40EA? Do I need to order any other components if I use two power supplies?

Hello,

 
To answer your questions, please see some recommendations for this device :
  • The CE8800&7800&6800&5800 series switches(except the CE8850-64CQ-EI) have two power supply slots, in which power modules can be installed to provide power to the chassis. A chassis can have one or two power modules. Double power modules can provide a higher reliability.

    The CE8800&7800&6800&5800 series switches(except the CE8850-64CQ-EI) support double power modules (1+1 backup).
    • When both power modules are working properly, they equally provide power for a chassis.
    • When one power module fails, the other one provides all power required for a chassis.
    All power modules are hot swappable.
  • Fan slot

    The CE8800&7800&6800&5800 series switches(except the CE8850-64CQ-EI) have two fan slots, in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability. A chassis must have two working fan modules to ensure normal operating.

    All fan modules are hot swappable.


Which power modules and fan slot are required for this switch ?

Other useful information :

The cooling systems of the CE8800&7800&6800&5800 series switches have front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used. The airflow direction of the power modules and fan modules required on the CE8800&7800&6800&5800 series switches depends on how the switches are installed in cabinets. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If CE8800&7800&6800&5800 series switches are installed with the power supply side facing the front, you are advised to use fan modules and power modules with front-to-back airflow in the switches.

  • Front-to-back airflow: The power modules and fan modules using front-to-back airflow are marked fig_dc_dcb_hw_000804.png or fig_dc_dcb_hw_003906.png. Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2 (CE5800 as an example).
  • Back-to-front airflow: The power modules and fan modules using back-to-front airflow are marked fig_dc_dcb_hw_000805.png or fig_dc_dcb_hw_003905.png. Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 3 (CE5800 as an example).
  • When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used.

Overall, you can have one power supply but 2 fan modules are required. And check the picture for exact part name, only some models are compatible.
