System Components
System Description
1-11
• Two types of operations ports for system management access—Craft and Ethernet:
— The XCRP and XCRP3 Controller cards have two Craft ports, labeled “CRAFT 1” and “CRAFT 2”;
the XCRP4 Controller card has a single Craft port, labeled “CRAFT”. Each port has a DB-9
connector and provides an RS-232 connection to a local console terminal, a terminal server, or a
modem. The Craft port provides access to the SmartEdge OS CLI for configuring and monitoring
task; it is enabled on both the active and standby controller cards.
— All controller cards have a single Ethernet port with an RJ-45 connector that runs at 100 Mbps and
provides a connection to an Ethernet device such as a switch or hub. This port provides access to
the SmartEdge OS CLI from either a local or remote management workstation for configuring and
monitoring tasks. Using this port, the system can also communicate with a remote workstation that
is running the NetOp EMS software.
• Temperature and voltage monitoring
Temperature is monitored at both air inlet and air outlet locations on a controller card;
an over-temperature interrupt signals the SmartEdge OS when the temperature rises above safe
operating conditions. Voltages are also monitored and reported to the SmartEdge OS. Administrators
can display both temperature and voltage data using commands in the SmartEdge OS CLI
• Fully redundant configuration:
— When two controller cards are installed in the SmartEdge 1200 chassis, one functions as the active
controller and the other card functions as the standby controller, providing full redundancy for
high-reliability networking requirements. In the event of a controller card failure, the redundant card
automatically becomes the active controller, thereby avoiding any unnecessary service disruption in
the network.
— Redundancy extends to the console connections on the controller cards: the console ports can each
be connected to a terminal server, and the Ethernet management ports can be connected to the same
Ethernet hub, with individual cables.
— The software automatically switches to the external timing secondary source should the primary
source fail. If both sources fail, the active controller card uses an internal timing source.
Note
The CRAFT 2 port is the only enabled Craft port on the XCRP and XCRP3 Controller cards.
Note
Support for 1-Gbps speed of the port on the XCRP4 Controller card depends on the release of
the SmartEdge OS.
Note
The Ethernet management port on the standby controller card is disabled unless the card
becomes the active controller card.
Note
If you upgrade the active controller card with a new software release, the active controller
upgrades the standby controller.
