Appendix C Ports and LEDs
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.
