Always-on infrastructure base—The PTX10008 is engineered with full hardware redundancy for cooling,
power, switch fabric, and host subsystems. The Routing and Control Boards (RCBs) allow service providers
to meet stringent service-level agreements across the core.
•
Nondisruptive software upgrades—The Junos operating system (Junos OS) on the PTX10008 supports
high availability (HA) features such as graceful Routing Engine switchover (GRES), and nonstop active
routing (NSR) providing software upgrades and changes without disrupting network traffic.
Chassis Description
The PTX10008 router is 13 U tall. Up to three PTX10008 routers can fit in a standard 42-U rack with
adequate cooling and power. All key PTX10008 router components are field-replaceable units (FRUs).
Figure 1 on page 26 illustrates the key components visible from the front of the chassis, Figure 2 on page 27
illustrates the components that are visible from the rear of the chassis, and Figure 3 on page 28 illustrates
the components that are internal to the chassis.
