The PTX3000 has a depth of only 10.6 inches, yet has a current capacity of 3.84 Terabits per second. Juniper has a plan to scale the system all the way up to 24 Tbps in a single box with future line card upgrades.
Mike Marcellin, SVP of strategy and marketing for the platform systems division at Juniper, explained to Enterprise Networking Planet that size-wise, up to four PTX3000s could fit in a single rack.

The PTX 3000 is an 8 slot chassis with up to 240G of forwarding per slot. Juniper currently has two interface choices, including an 24 x 10 Gigabit Ethernet interface as well as a 2 x 100 Gigabit Ethernet interface
