About the Juniper Networks EX4100-48MP Ethernet Switch
The Juniper Networks EX4100-48MP delivers enterprise-class switching with 48 ports of multi-rate 10/100/1000/2500/5000 Mbps PoE++ connectivity, backed by 8 × 10GbE SFP+ and 2 × 25GbE SFP28 uplink ports. This 1U rack-mountable design from Juniper combines high port density with substantial uplink capacity, making it ideal for mid-to-large campus networks, data center access layers, and IoT-heavy environments requiring extensive powered device support.
Network engineers and IT procurement teams will appreciate the robust feature set built into the EX4100-48MP. With a maximum PoE budget of 1,440W and 90W per port, the switch powers thousands of devices simultaneously—from IP phones and wireless access points to powered cameras and sensors. The platform supports Virtual Chassis operation (up to 10 members), delivering 336 Gbps of switching capacity and 250 Mpps forwarding throughput. Layer 2 and Layer 3 routing capabilities include OSPF, BGP, RIP, IS-IS, VRRP, and static routing, alongside comprehensive security and redundancy features such as RSTP, MSTP, LACP, 802.1X port authentication, and IGMP snooping. Management options span Junos OS CLI, NETCONF, RESTCONF, OpenConfig, and Juniper Mist AI cloud management integration, supported by dedicated out-of-band 1 × 10/100/1000 Mbps management and console ports. The switch operates reliably across 0°C to 45°C environments, suiting diverse deployment scenarios from climate-controlled data centers to field offices.

Frequently Asked Questions about Juniper Networks EX4100-48MP Ethernet Switch
Does the Juniper Networks EX4100-48MP Ethernet Switch support our SFP transceivers?
Most enterprise switches ship without transceivers; we quote vendor-matched optics alongside the switch (Cisco-genuine for Catalyst/Nexus, HPE/Aruba-genuine for CX, Juniper-genuine for QFX/EX). Third-party MSA-compatible options are also available at lower cost — specify preference in the RFQ.
Do you provide stacking / VPC / MLAG configuration help?
Yes — our network engineers can pre-stage stacking, VPC pairs, MLAG, EVPN-VXLAN, or fabric extender configurations in advance, or provide remote commissioning. Add commissioning to your RFQ.
What software licensing is included?
Switch software licensing varies by vendor. Cisco DNA / Cisco DCNM, Aruba CX licensing tiers, Juniper Premium, NVIDIA Cumulus — we quote the licensing tier matched to your features (BGP-EVPN, telemetry, automation). No surprises later.
Is the support global?
Yes — manufacturer hardware support is global (return-to-vendor or advance replacement depending on tier). For 24x7 same-day on-site replacement, attach a SmartNet / Foundation Care / J-Care contract during quoting.
