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 and views of H3C transceiver modules and cables, see H3C Transceiver Modules User Guide.

IMPORTANT: · BIDI transceiver modules transmit and receive different central wavelengths for bidirectional transmission of optical signals on a single fiber. · BIDI transceiver modules must be used in matched pairs. For example, if one end uses an SFP-XG-LX-SM1270-BIDI transceiver module, the other end must use an SFP-XG-LX-SM1330-BIDI transceiver module. |

Fan tray alarm LEDs
The FAN-40B-1-A and FAN-40F-1-A fan trays each provide an alarm LED. For more information about the LED, see the user guide for the fan tray.
Power supply alarm LEDs
The PSR450-12A, PSR450-12A1, PSR450-12AHD, and PSR450-12D power supplies each provide an alarm LED. For more information about the LED, see the user manual for the power supply.
5 Cooling system
CAUTION: The chassis and power supplies 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 provide adequate heat dissipation and ensure system stability. Consider the site ventilation design when you plan the installation site for the switch.
