The Summit1 has eight Gigabit Ethernet ports. Six of the ports use SC connectors and
support 1000Base-SX over 850nm Þber-optic cable. Ports 1 and 8 have GBIC connectors
and support the media types and distances listed in
Table 1-1
.
For more information on 1000Base-SX and 1000Base-LX link characteristics,
refer to IEEE Draft P802.3z/D3.1, Table 38-8.
