60-byte text string stored in the JCS management module NVRAM that conveys configuration
information to the Routing Engines (blades) in the JCS chassis.
Interface concentrator on which PICs are mounted. An FPC is inserted into a slot in a Juniper
Networks router. See also PIC.
A configuration that enables PSDs on the JCS1200 platform to communicate on a peer-to-peer
basis without requiring external links. Inter-PSD forwarding is achieved by using tunnel PICs
that reside on each PSD. The PSDs communicate over logical interfaces configured on the
tunnel PICs.
Chassis management hardware and software included used to access and configure the
Juniper Control System (JCS) platform.
Hardware device that connects Routing Engines in the Juniper Control System (JCS) chassis
to a Juniper Networks router and controls traffic between the two devices. For redundancy,
the JCS chassis can include two JCS switch modules.
OEM blade server customized to work with Juniper Networks routers. The JCS chassis holds
up to 12 single Routing Engines (or 6 redundant Routing Engine pairs). The JCS1200 chassis
connects to up to three T Series routers, enabling the control plane and forwarding plane of
a single interconnected platform to be scaled independently.
Physical Interface Card. A network interface-specific card that can be installed on an FPC in
the router.
One or more Flexible PIC Concentrators (FPCs) on a Juniper Networks router matched with a
Routing Engine (or redundant pair) on the JCS1200 platform to form a secure, virtual hardware
router.
