The
hme
device driver handles the
SUNW,hme
device on these hardware
devices:
•
SunSwift SBus Adapter
•
SunFastEthernet Adapter 2.0
•
Sun Ultra 1 Creator Series systems
•
Sun Ultra 2 Series system
•
Ultra Enterprise 3000, 4000, 5000, and 6000 systems
This chapter gives a hardware overview of the
SUNW,hme
device, provides
information on the operating speeds and modes for the
SUNW,hme
device, and
discusses auto-negotiation, the internal transceiver, and the external
transceiver for the
hme
device driver. Note that the external transceiver is not
present on the SunSwift SBus Adapter.
Hardware Overview
The
SUNW,hme
device provides 10BASE-TX or 100BASE-T networking
interfaces using the Fast Ethernet Parallel Port SCSI (FEPS) ASIC and an
internal transceiver. The driver automatically sets the link speed to 10 or 100
Mbps and conforms to the 100BASE-T IEEE 802.3u Ethernet standard. The
FEPS ASIC provides the SBus interface and Media Access Control (MAC)
functions. The internal transceiver, which connects to an RJ-45 connector on all
of the above hardware devices, provides the physical layer functions.
