High-speed link for Model 550
The Model 550 supports two HSL-2/RIO-G loops. The maximum rated speed of
the HSL-2/RIO-G is 2 Gbps, which is double the speed of the previous
HSL/HSL-2 adapters. The following rules apply to towers that are supported at
these speeds:
New #5094, #5294, #0595, and #5095s come with a #9517 HSL-2/RIO-G
adapter. The #5790 PCI-X Expansion Drawer includes a #9531 HSL-2/RIO-G
adapter.
HSL-2 adapters in existing #5094, #5294, #0595, and #5095 towers must be
replaced with a #6417 2 GBps HSL-2/RIO-G adapter.
Mixing of HSL and HSL-2 towers is permitted with the correct combination of
cables.
See “High-speed link” on page 293 for information about supported HSL cables
and HSL loop maximums. You can find further information in High-speed Link
