What ports are included on the EX4100-48MP-CHAS?

The chassis supports 56 total ports: 16x 100M/1GbE/2.5GbE multigigabit PoE++ access ports, 32x 10M/100M/1GbE PoE++ access ports, 4x 10GbE/25GbE uplink ports, and 4x 1GbE/10GbE ports. All access ports deliver up to 90W PoE++ per IEEE 802.3bt, ideal for high-power devices.

What is the switching performance?

It offers 212 Gbps unidirectional / 424 Gbps bidirectional switching capacity and 315 Mpps Layer 2/3 throughput with 64-byte packets. Supports 64,000 MAC addresses and jumbo frames up to 9216 bytes, ensuring wire-speed performance for enterprise access.

Does it support Virtual Chassis?

Yes, up to 10 EX4100 switches can form a Virtual Chassis using 4x 25GbE SFP28 ports, managed as a single logical device. This simplifies scaling and high availability with features like Uplink Failure Detection.

What management options are available?

Junos OS CLI, out-of-band management via serial and 10/100/1000BASE-T Ethernet. Protocols include SNMP v1/v2c/v3, RADIUS, TACACS+, SSHv2, NTP, and Mist AI for cloud-ready operations with Marvis Virtual Network Assistant.

What security features does it have?

Includes MACsec AES256 switch-to-switch encryption, MAC limiting, Dynamic ARP Inspection, IP source guard, DHCP snooping, and flow-based telemetry for anomaly detection. Supports group-based policies for microsegmentation.

Is this a complete switch or just the chassis?

This is a spare chassis only (no fans or PSUs included). It requires separate power supplies and fans for operation, designed for field replacement or upgrades in EX4100-48MP deployments.
