• AC power—The AC power supply has an IEC 320-type power receptacle and a 15 Amp service connector.
You can use standard right angle power cords with the AC power supply. The power supply includes a
power cord retainer. No ON/OFF switch is provided.
You can install dual power supplies for redundancy.
In low-line applications (90-140V AC), redundancy is not guaranteed. Therefore, we recommend to use both
AC and DC power supplies.
Caution
Products that have an AC power connection are required to have an external SPD provided as part of the
building installation to comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility
and safety.
Note
Do not use interface module and power supply ejector handles to lift the chassis; using the handles to lift the
chassis can deform or damage the handles.
