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

.
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.
