Temperature and Humidity
The operating environmental site requirements are listed in
XR 12406 Router Technical Specifications and Warnings.”
The temperature and
humidity ranges listed are those within which the Cisco XR 12406 Router will
continue to operate. You can maintain normal operation by anticipating and
correcting environmental irregularities before they approach critical values.
The environmental monitoring functionality built into the Cisco XR 12406 Router
protects the system and components from potential damage from overvoltage and
over temperature conditions. To assure normal operation and avoid maintenance
difficulty, plan and prepare your site before you install the router.
Power Connection Guidelines
A Cisco XR 12406 Router can be configured with either an AC-input power
subsystem or a DC-input power subsystem. Site power requirements differ
depending on which source power scheme is used. Follow these precautions and
recommendations when planning power connections to the router:
•
Check the power at your site before installation and periodically after
installation to ensure that you are receiving clean power.
•
If necessary, install a power conditioner.
•
Install proper grounding to avoid damage from lightning and power surges.
Note
When operating your router on a single power module, the second power
module bay must have a blank filler (MAS-GSR-PWRBLANK=)
installed to ensure EMI compliance.
