SCBE2 Redundancy

Copyright © 2016, Juniper Networks, Inc.
A bandwidth of up to 360 Gbps per slot with redundant fabric support and 480 Gbps
per slot without redundancy, and improved fabric performance on account of using
the next-generation fabric (XF2) chip.
A central clocking module and a centralized clocking architecture that support clock
cleanup and distribution. The Stratum 3 clock module performs clock monitoring,
filtering, and holdover at a centralized chassis location.
Full performance with fabric redundancy for higher-capacity line cards such as MPC4.
Support for MPC line cards only
Two 10-Gigabit Ethernet SFP+ ports
Support for cross-coupling of clock input (which requires an enhanced midplane:
CHAS-BP3-MX240-S). You can configure the system such that one SCBE2 supports
a GPS interface, and the other SCBE2 supports a BITS interface.
The Routing Engine is installed directly into a slot on the SCBE2 (see

Figure 37: SCBE2

You can install either one or two SCBE2s. SCBE2s are installed horizontally into the front
of the chassis in the slots labeled
panel.
The control boards operate in redundancy fabric mode by default. You can configure the
control board to be in redundancy mode or in increased fabric bandwidth mode.
