Juniper Networks EX4400 Multigigabit Switches Extension Models

4x10GbE SFP+ extension module

EX4400 switches provide a slot to install an optional extension module. Extension modules are hot-insertable and hot-removable field-replaceable units (FRUs): You can remove and replace them without powering off the switch or disrupting switch functions.

You can install an extension module horizontally in the extension module slot on the front panel of the switch. By installing an extension module, you add more ports to your switch, thereby increasing the port density of the switch.

You can install up to four 1GbE SFP transceivers or 10GbE SFP+ transceivers in the 4x10GbE SFP+ extension module. Do not install SFP transceivers and SFP+ transceivers in the extension module at the same time.
