Adds eight SFP+ slots for 10 GbE uplinks or Virtual Chassis links on Juniper EX4500 switches
The Juniper EX4550-EM-8XSFP adds eight SFP+ slots to compatible EX4500 switches, accepting 10-gigabit or 1-gigabit transceivers in any mix. It extends uplink density and supports Virtual Chassis port configuration for stacking multiple switches into a single logical device.
Each of the eight slots works with SFP+ or SFP optics, letting operators choose speed per link without replacing the module. Ports can be designated as Virtual Chassis ports, simplifying management by collapsing several physical switches into one control plane.
This module suits network teams running Juniper EX4500 hardware who require additional 10-gigabit uplinks or stacking links. It does not fit other switch families, so buyers with different platforms must seek a matching expansion card.

The module provides eight SFP+ cages; the cages themselves are passive and do not wear out, while any SFP or SFP+ transceiver you insert can be swapped individually when it reaches end of life.
Each of the eight SFP+ slots supports up to 10 GbE, so aggregate sustained throughput is bounded by the 10 GbE line rate per port and the EX4500 switch fabric behind the module.
The module has no onboard fans and draws power from the EX4500 chassis; thermal load is handled by the switch’s existing cooling system and is RoHS compliant.
