About the HSSDC FC-AL Port
The Sun Fire V490 system back panel includes an FC-AL port with a high-speed
serial data connector (HSSDC).
Note – At this time, no Sun storage products are supported utilizing the HSSDC
connector.
About the FC-AL Host Adapters
The Sun Fire V490 server uses an intelligent Fibre Channel processor as its on-board
FC-AL controller. Integrated into the system centerplane, the processor resides on
PCI Bus C and supports a 64-bit, 66-MHz PCI interface. The on-board FC-AL
controller controls FC-AL operations on Loop A.
To take advantage of the dual-loop capability of the FC-AL backplane, an optional
PCI FC-AL host adapter card and optional cable are required to control the second
loop (Loop B). For this purpose, Sun offers the Sun StorEdge PCI Dual Fibre Channel
Host Adapter card. See the Sun Fire V490 Server Parts Installation and Removal Guide,
which is included on the Sun Fire V490 Documentation CD, for installation
instructions.
Configuration Rules
■
The Sun Fire V490 server does not support all FC-AL host adapter cards. Contact
your Sun sales or support engineer for a list of supported cards.
■
For best performance, install 66-MHz FC-AL host adapter cards into a 66-MHz
PCI slot (slot 0 or 1, if available). See “About the PCI Cards and Buses” on
page 31.
Note – Do not attempt to access any internal components unless you are a qualified
service technician. Detailed service instructions can be found in the Sun Fire V490
Server Parts Installation and Removal Guide, which is included on the Sun Fire V490
Documentation CD.
