Introduction
1.1 Overview
The Centellis 2x00 User Card is an independent Field Replaceable Unit (FRU) for the
Centellis 2x00 system. It hosts an PHY for converting a 10Gbps XAUI Ethernet signal to a
Small Form-factor Pluggable (SFP) connector on the face plate. It has independent power
supply derived from the 48V and a 3.3V management supply. It supports full management
access via two IPMBs and accesses one Fabric Interface (FI) of the corresponding
AdvancedTCA blade.
The Centellis 2x00 User Card-10GE module is intended to be used in a Centellis 2x00
chassis. The module when installed in the dedicated User Card slot provides uplink
connectivity from the payload Ethernet fabric channel.
Figure 1-1 shows the functional block diagram of the Centellis 2x00 chassis including the
two 10G User Cards in the lower part of the figure.
Each 10G User Card is connected through the chassis backplane to fabric channel 2 of one
front board via 4x bidirectional Low Voltage Differential Signal (LVDS) signals. The LVDS
signals provide the XAUI 10G Ethernet interface which is converted by the 10G User Card
to a serial 10G Ethernet interface on an SFP+ module.
