Does the module support N+1 redundancy?

Yes. The design allows N+1 power redundancy across four slots, ensuring uninterrupted operation if one PEM fails. You can install an extra module for full redundancy.

Which chassis models are compatible with SKU 12000/4-DC-PEM?

This DC PEM is compatible with Cisco 12000 series chassis, including Cisco 12012, 12016, and 12008. Verify chassis firmware meets minimum Cisco IOS release requirements.

How do I install the Cisco 12000 DC PEM?

Slide the module into an available PEM bay until it clicks, then secure the captive screws. Connect the –48 VDC input cables and verify status LEDs indicate normal operation.

What monitoring features are available?

The module offers real-time power metrics via Cisco IOS MIBs and CLI commands. You can monitor input voltage, current draw, module temperature, and fault status for proactive management.

What are the physical dimensions and weight?

The 4-slot DC PEM measures 89 mm (H) x 235 mm (W) x 280 mm (D) and weighs approximately 3.5 kg. Its compact form factor fits standard 12000 series power bays.

What environmental conditions does it require?

Operating temperature ranges from 0°C to 40°C (32°F to 104°F) with up to 10,000 ft (3,048 m) altitude. It meets ETSI, NEBS, and ETSI ETS 300-019 compliance for humidity and vibration.

Which certifications and compliance standards are met?

The PEM is UL-listed, CE-marked, and complies with FCC Class A, RoHS, and NEBS Level 3. It meets international safety and EMC requirements for carrier-grade deployments.
