Juniper EX4600 Hardware Guide

Benets of the EX4600 Switch
Compact soluon—The EX4600 switch supports up to 72 10-Gigabit Ethernet ports in a 1 rack unit (1 U)
chassis.
Intelligent buer management—EX4600 switches have a total of 12 MB shared buers. While 25
percent of the total buer space is dedicated, the rest is shared among all ports and is user congurable.
The intelligent buer mechanism in the EX4600 eecvely absorbs trac bursts while providing
determinisc performance, signicantly increasing performance over stac allocaon.
Energy eciency—The 10-Gigabit Ethernet ports consume less than ve was, thereby oering a low
power soluon for top-of-rack, end-of-row, and distribuon deployments.
EX4600 Hardware
The EX4600 switch is a compact 1 U model that provides wire-speed packet performance, very low
latency, and a rich set of Layer 2 and Layer 3 features. In addion to a high-throughput Packet
Forwarding Engine, the performance of the control plane running on the EX4600 model is enhanced by
the 1.5-GHz dual-core Intel CPU with 32 GB of solid-state drive (SSD) storage.
The port panel of the EX4600 features 24 xed small form-factor pluggable (SFP) or SFP+ access ports
and 4 xed quad SFP+ (QSFP+) high-speed uplinks.

In addion, the switch has two module bays where you can install oponal expansion modules. The
EX4600 switch supports two expansion modules to increase port density:
