What is the switching performance of JC105B?

Switching capacity is 256 Gbps with 155 Mpps throughput. Features cut-through design for low latency (~4 µs on 64-byte packets), large MAC table (32k entries), and IPv4 routing table (16k entries), ensuring wire-speed Layer 2/3 performance in high-density environments.

Does it support Layer 3 features?

Yes, as a managed Layer 3 Ethernet switch, it provides full Layer 2/3 dual-stack IPv4/IPv6 capabilities, including routing. Supports IEEE 802.1AB LLDP for discovery and secure CLI management over IP networks for remote administration.

What power options are available?

Requires redundant, hot-swappable power supplies JC680A or JC681A (not included). Supports AC 100-240V, 50/60 Hz with max heat dissipation around 358-557 BTU/hr depending on load, ensuring high availability in rack deployments.

What is the form factor and environment specs?

1U rack-mountable fixed switch. Operating temperature 0°C to 45°C (32°F to 113°F), humidity 10-90% non-condensing. Acoustic: 45.3 dB low-speed fan, 56.5 dB high-speed, suitable for data centers and wiring closets.

Is it suitable for data center use?

Yes, ideal for data center edge/distribution with 256 Gbps capacity, 4x10G SFP+ ports, and IRF technology for resilient fabrics. Supports up to 84 ports with modules, low latency, and redundant components for high-performance convergence.
