5-10 Netra CP3260 Blade Server User’s Guide • April 2009
5.2.3.1 PCI Express Switch
The Netra CP3260 uses the PLX PCI switch that encompasses a 32-lane PCI Express
switch with six configurable ports (x1, x2, x4, x8, x16).
5.2.3.2 Base Interface
The Netra CP3260 provides dual redundant 10/100/1000BASE-T Ethernet links to
connect to the midplane Base interface channels. A x4 lane port from the PCI Express
switch connects to a dual gigabit controller.
5.2.3.3 Fabric Interface
The dual XAUI ports from UltraSPARC T2 processor are multiplexed between the
midplane Zone 2 connector (that is, the fabric interface). The XAUI interface operate
at 10-Gbps or 1-Gbps.
5.2.3.4 Common ARTM
The Netra CP3260 provides a Zone 3 interface to a common ARTM which essentially
appears as an AMC card. The common ARTM supports the AMC.1 and AMC.2
compliant interfaces.
An X8 PCI Express channel is routed to the RTM slot.
The ARTM interface provides an Ethernet SERDES interface for AMC.2 compliant
functionality. These ports are sourced from the dual Gigabit Ethernet controller that
connects to the PCI Express switch using a x4 lane PCI-E channels. (See
Section 5.2.4,
“Other ARTM Interfaces” on page 5-11 for other non-AMC interfaces routed to the
ARTM.)
ARTM Power and Management
The common ARTMs require two voltages:
■
3.3V STBY for management (current limited to 100 mA)
■
12V power for payload on ARTM (Maximum 25 Watts).
Power management is handled by the ATCA shelf manager’s Intelligent Platform
Management Controller (IPMC).
