Product Review

The Cisco ASR-920-24TZ-M offers a solid combination of 24 Gigabit Ethernet ports and 4 10-Gigabit Ethernet ports, supporting diverse connectivity needs for high-speed data transfer and network scalability. Its modular power supply design and dual power supply support enhance system reliability and uptime, crucial for mission-critical network operations. However, the device's power consumption at 130W may be a consideration for energy-conscious deployments, especially in environments striving for reduced operational costs.


The Cisco ASR-920-24TZ-M is designed to deliver high-capacity, resilient, and secure aggregation in a compact form factor. It runs on Cisco IOS® XE software, ensuring streamlined management and operation. This device is equipped with 24 Gigabit Ethernet Copper ports and 4 10 Gigabit Ethernet ports, providing ample connectivity for a variety of network configurations and bandwidth requirements. The unit dimensions are 1.72 inches in height, 17.5 inches in width, and 10 inches in depth, making it an ideal fit for space-constrained environments. With a weight of 3.8 kg for the empty chassis, it is relatively lightweight, facilitating easy installation and maintenance. The rack size is standardized at 1 Rack Unit (RU), optimizing rack space in data centers or network closets. For mounting, the Cisco ASR-920-24TZ-M offers flexibility with options including an ETSI Rack-Mount Kit, a 19-inch Rack-Mount Kit, and a 23-inch Rack-Mount Kit. This ensures compatibility with various rack standards and setups. The device supports dual power supplies, with the option for either AC or DC input. This redundancy enhances system reliability, ensuring uninterrupted operation even if one power source fails. The Mean Time Between Failure (MTBF) is reported at 582,610 hours, indicating a high level of reliability over the device's operational lifespan. Power efficiency is a key consideration, with a typical power consumption of 130 Watts. This efficiency is supported by a wide range of input power options, including AC power from 100 V to 240 V and DC power from -36 V to -72 V. Operating conditions for the ASR-920-24TZ-M are broad, capable of functioning in temperatures ranging from -40 °C to 70 °C, and at altitudes up to 1,000 feet. The device can operate effectively within a relative humidity range of 5% to 95% (non-condensing), ensuring performance stability across various environmental conditions. Storage conditions are similarly resilient, accommodating storage temperatures from -40 °C to 70 °C, and at altitudes up to 15,000 feet. This robustness is complemented by compliance with Seismic Zone 4 standards, illustrating the device's durability in physically demanding environments.
  • Electromagnetic compliance is achieved with FCC CFR47 Part 15 Class A certification.
  • Safety standards are rigorously met, including UL 60950-1, CAN/CSA C22.2 No. 60950-1, and several international safety standards.
  • NEBS certifications (GR-63-CORE, GR-1089-CORE, and SR-3580 NEBS Level 4) are in place, confirming its suitability for use in network facilities with stringent requirements.
In summary, the Cisco ASR-920-24TZ-M is a high-performance, reliable, and versatile networking solution. Its compact size, combined with powerful hardware specifications and compliance with numerous safety and operational standards, makes it suitable for a wide range of industrial and enterprise applications.
