Interface speed
•
1000 Mbps (recommended)
•
Full duplex
The following transceiver modules are available for the HIM-4GBP/HIM-8GBP:
•
100 Mbps fiber SFP transceiver modules.
•
1000 Mbps fiber SFP transceiver modules.
•
100/1000 Mbps fiber SFP transceiver modules.
•
10/100/1000 Mbps copper SFP transceiver modules (support for 10/100/1000 Mbps
autosensing on the HIM-4GBP/HIM-8GBP).
Prepare the transceiver modules yourself as required.
H3C recommends that you use H3C SFP transceiver modules for the device. H3C does not guarantee the
compatibility of SFP transceiver modules from other vendors with the device. The device reports an alarm
when non-H3C SFP transceiver modules are installed.
Interface cables
Use interface cables for the HIM-4GBP/HIM-8GBP as follows:
•
Fiber SFP transceiver module
—Fibers with the LC connector.
•
Copper SFP transceiver module
—Category-5 straight-through or crossover twisted pair cable when
the port is operating at 10/100 Mbps and Category-6 twisted pair cable when the port is
operating at 1000 Mbps.
