Egress Modules
Each Egress (non-DOCSIS) module has an independent network processor
and Synchronous Burst RAM sources. As a result, processing power and
memory scale with every module that you install in the chassis.
Octal 10/100 Ethernet SpectraFlow Modules
The Octal 10/100 Ethernet SpectraFlow module (Figure 1-11) contains eight
auto negotiating 10/100BASE-TX Fast Ethernet ports that support
connection to UTP Category 5 copper wire. The module auto senses 10/100
Mbps, full duplex, and half duplex connections and complies with all IEEE
802.3u specifications. The module is hot-swappable; this means you can
remove and replace the module with the system powered on and running.
Connection to this module is achieved though the RJ-21 Champ-style
connector mounted on the rear chassis for slots 1 through 11. Cabling to the
RJ-21 connector and not to the module itself allows you to remove and
replace the module without re-cabling. It also allows you to cable slots in
advance.
Chassis slot 12 does not have a RJ-21 connector associated with it and does
not support installation of 10/100 Ethernet SpectraFlow modules.
The module functions as a layer 3 switch and forwards packets at wire speed
on all ports simultaneously; it supports a transmission distance of up to 100
meters.

In addition to the common module components found on each application
module, the 10/100 Ethernet SpectraFlow module offers an LED port status
display consisting of eight rows of four LEDs—one row for each Ethernet
port. For each Ethernet interface, these LED status are shown:
Wire Type Transmission Distance Line Ratio
UTP Cat 5 100 meters 10/100 Mbps
LED Description
ACTIVE Illuminates when forwarding data.
FDX Indicates full-duplex link.
LINK Indicates a valid link to the network.
