This product requires surge protection as part of the building installation. To comply with the Telcordia GR-1089 NEBS
standard for electromagnetic compatibility and safety, an external surge protective device (SPD) is required at the AC power
service equipment.
Note
For DC systems, if a surge of more than 500 V is expected, add an appropriate external surge protective device.
Note
The routers support AC and DC power supplies in a 1+1 redundant configuration.
One AC and one DC power supply in the same router is also a supported configuration.
Note
The router has a single fan-tray with four fans. The system is designed to operate at its maximum operating temperature of 70º C, in
case of failure of a single fan operating temperature of 65º C. The fan tray is field-replaceable.
Licensing
The router supports the following types of licenses:
• Port Licensing—Port Upgrade license is available as a "Pay as you Grow" model.
• 6 ports 1GE upgrade license
• 2 ports 10G upgrade license
• Bulk License to enable 12x1port 1GE and 4x10GE ports
