Expansion module for 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.

Flexible transceiver mix and stacking

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.

For EX4500 owners needing more uplinks

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.

Questions about this item

Will the eight SFP+ cages or the transceivers inserted in them need periodic replacement?

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.

What limits sustained throughput when all eight ports run at 10 GbE?

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.

Does the expansion module add fan noise or heat when the EX4500 runs continuously?

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.
