EX9200-SF3 Components and Features
Component/Feature Descripon
XGE ports Two Ethernet ports provide 10GbE and 1GbE SFP+ interfaces. These ports also are
connected to the Ethernet control switch, which limits the trac for the 10GbE port
and provides security to prevent unwanted access to the control plane through the
external ports.
GPS port One RJ-45 GPS external clock interface port receives GPS and PPS ming from the
GPS external interface. A red LED indicates there is no clock present or the clock is
not OK. A green LED indicates the clock interface is acve and OK. If the LED is o,
the clock interface is not enabled.
External clock interface The external clock interface is on the EX9200-SF3 front panel. The clock source
interface receives GPS and PPS ming from the GPS external interface.
Centralized Stratum3E
clock module
The clock module performs clock monitoring, ltering, and holdover on the
centralized fabric card. This centralized clocking architecture also provides clock
cleanup and distribuon.
In-system removable
Roung Engine
The in-system Roung Engine can support any new Roung Engine that conforms to
the standard modular Roung Engine I/O interface and form factor.
NOTE: When a Roung Engine is not installed in the EX9200-SF3, you need to
cover the empty slot with a blank panel.
Hot-swappable The EX9200-SF3 and associated Roung Engine assembly are hot-swappable. The
system soware provides a mechanism to shut down the Roung Engine/EX9200-
SF3. The system soware also provides a method to reset or reboot the Roung
Engine/EX9200-SF3. This support is provided through CLI commands and various
hardware support circuits.
NOTE: Before removing the module, you must bring the Roung Engine oine to
avoid corrupng the hard drive.
