Product Review

The Juniper MX40-T-AC router offers a notable balance of performance and expandability, with its 60 Gbps throughput and flexibility through 2 fixed 10GbE ports plus 3 MIC slots for customization. However, its limitation to a maximum of 4 10GbE ports and a system capacity of 80 Gbps might not meet the demands of larger, more data-intensive networks. Additionally, its operational power draw of 365W and a weight of 30 lb/13.7 kg when fully loaded could be considered drawbacks for deployments sensitive to energy consumption and physical space.
