Common questions
Is this a complete system?
No. This is the spare chassis. Power supplies and fans are ordered separately.
What do I order if I need a working switch, not just the chassis?
Order the EX4100-48MP (AC power, front-to-back airflow) instead. It is the complete switch listed next to this spare chassis on this page.
Does this spare retain the SFP28 connections?
Yes. The chassis has four SFP28 stacking/uplink ports and supports up to 10 Virtual Chassis members.
