Juniper EX4550 Hardware Guide

You can manageEX4550 switches by using the same interfaces that youuse for managing
other devices running Juniper Networks Junos operating system (Junos OS)—the CLI, the
J-Web graphical interface, and Junos Space.

Software
Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and
Layer 3 switching, routing, and security services. The same Junos OS code base that runs
on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series
routers, and SRX Series Services Gateways. For information about installing software
for your switch, see Software Installation.
EX4550 Switches First View
EX4550 switches provide connectivity for high-density 10-Gigabit Ethernet data center
top-of-rack, enterprise, and campusaggregationand core deployments. EX4550 switches
can be used in large branch offices, campus wiring closets, and data centers where they
can be positioned as the top device in a rack to provide connectivity for all devices in the
rack.
EX4550 switches are available in two base switches—a 32-port SFP+ based switch
(EX4550-32F), which provides 32 fixed 10-Gigabit SFP+ ports in which you can install
1-gigabit SFP or 10-gigabit SFP+ transceivers and a 32-port 10GBASE-T based switch
(EX4550-32T), which provides 32 fixed 10-Gigabit Ethernet BASE-T ports in which you
can install 100-Megabit, 1-Gigabit, or 10-Gigabit BASE-T connectors. See “EX4550 Switch
Models” on page 9.
EX4550 switches have different airflow directions in the chassis. EX4550 switches provide
two module slots, each of which can house any one of the following optional modules:
•
8-port 10-Gigabit SFP+ expansion module
•
8-port 10GBASE-T expansion module
•
2-port 40-Gigabit QSFP+ expansion module
•
128-Gigabit Virtual Chassis module
