This product requires surge protection as part of the building installation. To comply with the Telcordia
Note
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.
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.

LED Indicators

This section describes the different types of LEDs and their behavior.

PWR and STAT LEDs

The PWR LEDs are available on the front panel. These LEDs provide power on the board (PWR) status.
During power up state, these LEDs provide booting status and report errors.
Note The digital code signing functionality validates the integrity and authenticity of the ROMMON image
before booting it.
