IBM j-type Ethernet switches and routers

Running Juniper Networks’ JUNOS® Software operating system, the IBM Ethernet Switch J48E was designed for high-performance server access deployments. A single switch can be deployed initially; as requirements grow, Virtual Chassis technology allows up to nine additional switches to be interconnected over a 128 gigabit-per-second (Gbps) backplane and managed as a single device, with a single configuration file and OS image. Modular Gigabit Ethernet (GbE) and 10-Gigabit Ethernet (10 GbE) uplink module options enable Virtual Chassis technology to be extended to switches in different racks or even in different data centers.

• Host ports48 10/100/1000BASE-T ports.
  
  Rear-panel Virtual Chassis ports support 128 Gigabit per second (Gbps) backplane connections to other IBM J48E switches in a Virtual Chassis configuration.
  
  Optional GbE (four) and 10 GbE (two) front-panel uplink ports.
