What is the performance of this switch chassis?

Switch fabric speed is 3.8 Gbps with 4.67 million pps throughput and latency under 10 µs (LIFO). Powered by Intel i960JD at 66 MHz, it includes 512 KB/port buffering for 10/100 and 4 MB for Gigabit, ensuring efficient handling of mixed traffic.

What is the address table capacity?

The chassis supports a 10,000-entry MAC address table, suitable for large-scale networks with many devices. This enables robust Layer 2 forwarding, VLAN support, and minimal flooding in environments with thousands of endpoints.

What are the physical and environmental specs?

Form factor is an empty chassis with 10 slots, rack-mountable in standard 19-inch racks. Operating temperature ranges from 32°F to 131°F (0°C to 55°C), providing reliability in data centers or offices with varying conditions.

Is this chassis pre-populated with modules?

No, the J4121-61001 is an empty chassis with 10 expansion slots, unlike some configurations with preinstalled modules. This allows IT teams full flexibility in selecting and installing compatible ProCurve modules for specific port needs.

What product type is the ProCurve 4000M?

It is a managed modular Ethernet switch chassis from the ProCurve 4000M line, designed for enterprise use. Key specs include 10 slots, 3.8 Gbps fabric, and 10K address table, ideal for core switching in modular architectures.
