CAUTION: The switch has five fan tray slots. To ensure good ventilation of the switch, follow these guidelines to install and remove fan trays: · The switch comes with the fan tray slots empty. As a best practice to ensure adequate heat dissipation, install fan trays of the same model on the switch. Before powering on the switch, make sure the number of installed fan trays meets the minimum requirement. · Make sure all slots have a module or filler panel installed when the switch is operating. · If multiple fan trays fail on an operating switch, do not remove the fan trays at the same time. Replace the fan trays one after another and finish replacing each fan tray within 3 minutes. |
The switch supports the FAN-80B-1-B fan tray.

As a best practice, use H3C transceiver modules and cables for the switch. H3C transceiver modules and cables are subject to change over time. For the most up-to-date list of H3C transceiver modules and cables, contact H3C Support or marketing staff.
For information about the specifications of H3C transceiver modules and cables, see H3C Transceiver Modules User Guide.
The switch uses high-power ports in high density. Bringing up the ports simultaneously takes a comparatively long time. To reduce the time to bring up a port, the system does not turn off the laser transmitter on the transceiver module when shutting down the port.
Console port
The switch has a serial console port and a mini USB console port.

6 Cooling system
|
|
CAUTION: The chassis and power modules use separate air aisles. Make sure the two aisles are not blocked when the switch is operating. |
The switch uses a highly efficient front-rear air aisle cooling system to ensure adequate heat dissipation and improve system reliability. Consider the ventilation design at the installation site when you plan the installation location for the switch.

7 Cable routing recommendations
You can purchase one cable management frame for the switch and install it on the rack posts immediately above or below the switch as required. For more organized cabling, you can purchase two cable management frames so that the switch has a cable management frame installed both above and below it.
Route the signal cables along the left or right side of the cable management frame as required. Cable routing in Figure7-1 is for your reference.
