NonStop NS16000 Series Planning Guide (H06.11+)

A G4SA can be configured as:
• Two 10/100/1000 Mbps copper ports and two 10/100 Mbps copper ports
• Two 10/100/1000 Mbps multimode fiber-optic ports and two 10/100 Mbps copper ports
A G4SA complies with the 1000 Base-T standard (802.3ab), 1000 Base-SX standard (802.3z),
and these Ethernet LANs:
• 802.3 (10 Base-T)
• 802.1Q (VLAN tag-aware switch)
• 802.3u (Auto negotiate)
• 802.3x (Flow control)
• 802.3u (100 Base-T and 1000 Base-T)
For detailed information on the G4SA, see the NonStop Gigabit Ethernet 4-Port Installation and
Support Guide.
Fibre Channel Disk Module
The Fibre Channel disk module is a rackmounted enclosure that contains:
• Up to 14 Fibre Channel arbitrated loop disk drives (enclosure front)
• Environmental monitoring unit (EMU) (enclosure rear)
• Fibre Channel arbitrated loop (FC-AL) modules (enclosure rear)
A Fibre Channel disk module connects to a FCSA in an IOAM enclosure. You can daisy-chain
together up to four Fibre Channel disk modules with 14 drives in each one. This illustration shows
a fully populated Fibre Channel disk module:
