HPE Juniper Networking EX4550-EM-8XSFP 8 Port Switch Module

SKU CH-S3SN-A85P1

Adds eight 10/100/1000 WAN ports with 10 Gbps switching capacity in a compact module

  • 8 WAN ports support 10/100/1000 speeds for flexible connectivity
  • 10 Gbps switching capacity handles demanding traffic loads
  • Compact 1 x 5 x 6 inch form factor fits dense racks
  • Lightweight 1.5 lb design eases installation and maintenance
  • Purpose-built for EX4550 chassis to expand port density

Network Expansion Module

The Juniper Networks EX4550-EM-8XSFP adds eight 10/100/1000 WAN ports to compatible EX4550 switches. It targets network administrators who need additional copper connectivity without replacing the base chassis. The module delivers a switching capacity of 10 Gbps to handle aggregated traffic loads.

Thermal and Power Profile

The unit operates with zero PoE power budget, so it draws no extra current for powered devices. Its compact 1.5 lb form factor fits within the existing switch airflow path without requiring additional cooling capacity. The module adds no PoE load to the power supply, keeping power draw predictable.

Integration Requirements

The module slides into an available expansion slot on a supported EX4550 chassis, consuming no rack units of its own. It frees up the base switch ports for uplink or fibre connections while extending copper reach. Compatibility is limited to the EX4550 platform, so it cannot be used in other switch families.

Questions about this item

How is the EX4550-EM-8XSFP module installed in the chassis, and what step is often missed?

Slide the module into an empty slot until the ejector lever clicks, then tighten the captive screws to secure the electrical connection.

What maintenance or replacement will the EX4550-EM-8XSFP need over time?

The module has no moving parts; only the SFP transceivers inserted into its eight ports may need replacement if a link fails or speeds change.

What throughput limit appears first when the EX4550-EM-8XSFP runs at sustained load?

The 10 Gbps switching capacity caps total bidirectional traffic before the eight 10/100/1000 ports reach individual line-rate saturation.
