product-line-qfx5100QFX5100 switches are flexible data center switching platforms that provide a universal building block for multiple fabric architectures, including Juniper’s mixed 1/10/40GbE Virtual Chassis, Virtual Chassis Fabric, Junos Fusion and QFabric® System architectures, as well as open architectures such as Spine and Leaf, Layer 3 and Open Clos IP fabrics. All QFX5100 switches support unified in-service software upgrades (unified ISSU) to deliver hitless data center operations for high availability. QFX5100 switches also include support for virtualized network environments including Juniper Contrail and VMware NSX Layer 2 gateway services.

To list the QFX3500 device and components and their serial numbers, use the show chassis hardware CLI operational mode command. 

show chassis hardware

ou use bellow command ( in example we are use two SN because we use virtual chassis ):

show configuration | display set | grep serial
Chassis SN from configuration

Much faster for take serial numbers from QFX5100 worked in virtual chassis use this command:

show virtual-chassis
show virtual-chassis

show virtual-chassis
