LEDs
The LEDs on the switch provide activity or status information.
For detailed information on all of the switch LEDs, see “Configuring the MSA
SAN Switch 2/8.”
Optical Ports
All optical ports support full fabric capability, allowing the MSA SAN Switch to
link or cascade to other HP StorageWorks Fibre Channel switches, building a
highly scalable SAN fabric.
The optical ports are connected via Small Form Factor Pluggable (SFP) media,
which are universal and self-configuring.
Each optical port supports link speeds up to 2 Gb/s and, independent of the other
ports, automatically negotiates to the highest speed possible for the devices
connected to that port.
These ports conform to the American National Standards Institute (ANSI) Fibre
Channel, FC-PI specification for Fibre Channel SFP transceivers.
The optical ports are numbered from left to right and are color-coded into two
groups, indicating which ports can be used in the same ISL Trunking group.
ISL trunking is an optional feature that enables distribution of traffic over the
combined bandwidth of up to four ISLs between two directly connected switches,
while preserving in-order delivery. Ports 1 through 3 can be used in a three-port
trunking group and ports 4 through 7 can be used in a four-port trunking group,
creating aggregate bandwidths of 6 Gb/s and 8 Gb/s, respectively. For specific
information about ISL trunking, refer to the HP StorageWorks ISL Trunking User
Guide. This guide is included on the documentation CD, included in the shipping
carton.
