M160 Internet Router Overview
The M160 Internet router provides a dense, highly redundant platform primarily for
large backbone core IP networks where switching fabric and Routing Engine
redundancy are required. The M160 router supports the JUNOS software which
provides router configuration and monitoring. (See Figure 7.)
Figure 7: M160 Router
The Type 1 Flexible PIC Concentrators (FPCs) for the M40e and M160 routers are
interchangeable. The M160 router supports two types of FPCs: FPC1 supports
Physical Interface Cards (PICs), including the single-port OC12 and Gigabit
Ethernet; and FPC2 supports higher-speed PICs, including OC48 and Tunnel
Services. The router can operate with any combination of FPC1s and FPC2s
installed. For more information about supported PICs and FPCs for each M-series
router type, see the appropriate PIC installation guide.
The M160 router accepts only DC power supplies.
