The triangular yellow LED lights to indicate a less severe condition that requires monitoring or maintenance. Both LEDs can be lit simultaneously.
Chapter 2: M7i Hardware Components The router supports various PICs, including ATM, Channelized, Gigabit Ethernet, Services, and SONET/SDH interfaces. You can install PICs of different media types on the same router as long as the router supports those PICs. Blank PICs resemble other PICs but do not provide any physical connection or activity. When a slot is not occupied by a PIC, you must insert a blank PIC to fill the empty slot and ensure proper cooling of the system.

After powering on a power supply, wait at least 60 seconds before turning it off. If the router is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the router again, first issue the CLI request system halt command.

CHAPTER 3 System Architecture Overview • System Architecture Overview on page 29 • M7i and M10i Packet Forwarding Engine Architecture on page 30 • Routing Engine Architecture on page 31 System Architecture Overview The router architecture consists of two major components: • Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. • Routing Engine—Provides Layer 3 routing services and network management.
M7i Multiservice Edge Router Hardware Guide M7i and M10i Packet Forwarding Engine Architecture The Packet Forwarding Engine performs Layer 2 and Layer 3 packet switching. The Packet Forwarding Engine is implemented in application-specific integrated circuits (ASICs). It uses a centralized route lookup engine and shared memory.
Chapter 3: System Architecture Overview 5. The integrated ASIC reassembles data cells stored in shared memory into data packets as they are ready for transmission and passes them to the outbound networking interface. 6. The outbound networking interface transmits the data packets.
M7i Multiservice Edge Router Hardware Guide Figure 21: Routing Engine Architecture Routing Engine Functions The Routing Engine handles all routing protocol processes, as well as the software processes that control the router's interfaces, the chassis components, system management, and user access to the router. These routing and software processes run on top of a kernel that interacts with the Packet Forwarding Engine.
Chapter 3: System Architecture Overview The Routing Engine constructs and maintains one or more routing tables (see Figure 22 on page 33). From the routing tables, the Routing Engine derives a table of active routes, called the forwarding table, which is then copied into the Packet Forwarding Engine. The design of the ASICs allow the forwarding table in the Packet Forwarding Engine to be updated without interrupting forwarding performance.

Appendix E: Cable and Wire Guidelines and Specifications for the M7i Router Signal Loss in Multimode and Single-Mode Fiber-Optic Cable for the M7i Router Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber). Interfaces with multimode optics typically use LEDs as light sources. LEDs are not coherent sources, however. They spray varying wavelengths of light into the multimode fiber, which reflects the light at different angles.
M7i Multiservice Edge Router Hardware Guide Dispersion is the spreading of the signal in time. The following two types of dispersion can affect an optical data link: • Chromatic dispersion—Spreading of the signal in time resulting from the different speeds of light rays. • Modal dispersion—Spreading of the signal in time resulting from the different propagation modes in the fiber.
Appendix E: Cable and Wire Guidelines and Specifications for the M7i Router The following hypothetical power budget equation uses values measured in decibels (dB) and decibels referred to one milliwatt (dBm): P =P –P B T R P = –15 dBm – (–28 dBm) B P = 13 dB B Related Documentation • Fiber-Optic and Network Cable Specifications for the M7i Router on page 178 • Signal Loss in Multimode and Single-Mode Fiber-Optic Cable for the M7i Router on page 179 • Attenuation and Dispersion in Fiber-Optic Cab
