Federal Communications Commission (FCC) Compliance Notice: Radio Frequency Notice
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operat ed in a commercial environment. Th is equipment generates, uses, an d can radiate radio
frequency energy. If it is not installed and used in accordance with the instruction manual, it may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case users will be requ ired to take whatever measures may be necessary to correct the
interference at their own expense.

• Switch configuration and management (page 1-7
Overview of the Switch Modules
The EtherSpeedII 10/100BASE-T 20-Port Switch Module provides 20 RJ-45
10/100 megabit per second (Mb/s) autonegotiation ports that support servers,
routers, or dedicat ed connections to user s (Figure 1-1
also support multiple users through a shared-media hub connection to a port.
The EtherSpeedII 100BASE-FX 16-Port Switch Module provides 16 MT-RJ 100
Mb/s fiber ports for connections that support connections to other 100BASE-FX
devices, f or example, switches, servers, and routers.

Features of the Switch Modules
The Centillion EtherSpeedII 10/100BASE-T 20-Port Switch Module and the
Centillion EtherSpeedII 100BASE-FX 16-Port Switch Module offer the following
features:
• Wire-speed, port-to-port, packet transfer
• Single-slot design to fit into the Centillion 50/100 chassis
• Autonegotiation of Ethernet 10/100 Mb/s speed
(EtherSpeedII 10/100BASE-T switch module only)
• Layer 2 MAC address-based switching
• Local frame switching, module-to-module switching, backplane switching,
and riser switching
• 200 MHz RISC processor

Overview of the EtherSpeedII Switch Modules
• 20 RJ-45 UTP network interface connectors
(EtherSpeedII 10/100BASE-T switch module only)
• 16 MT-RJ fiber connectors (EtherSpeedII 100BASE-FX switch module only)
• Front-panel LEDs to indicate port status
• Port-based virtual LANs (VLANs)
• Protocol-based VLANs
Protocol-sensitive VLANs classify packets based on protocol types. Most
customers have multiple protocols per LAN segment, so a switch port needs
to support multiple VLANs based on different protocol types. This feature
allows you to separate da ta based on prot ocols and not on ph ysical limitat ions.
• IEEE 802.1Q tag recognition support
EtherSpeedII switch modules support recognition of VLAN tagged frames
based on IEEE 802.1Q tags. Frames entering an EtherSpeedII switch module
port that contain an 802.1Q tag are mapped to a corr esp ondi ng VLAN. Bas ed
on the final destination, the frame is sent as either an Ethernet-type frame or
an 802.1Q VLAN tagged frame. VLAN membership can be assigned by any
combination of port with either tag or protocol.
• Support for IEEE 802.1d Spanning Tree
• Content-addressable memory (CAM) support for 8192 entries
• Port steering/port mirroring
• Input and output filtering supported by switching software
• Hardware support for IP multicast
• Support for RMON Management Information Base (MIB)

MPOA is the ATM Forum standard that specifies a method to efficiently
transport intersubnet unicast data in a LAN emulation (LANE) environment.
MPOA uses LANE and Next Hop Resolution Protocol (NHRP) processes to
allow direct shortcut vir tual channe l connecti ons (VCCs) to be estab lished for
intersubnet communication without requiring passage through a router. The
intrasubnet communication continues to be supported over LANE. For IP,
Nortel Networks has adopted MPOA as the standard to implement layer 3
switching in an ATM network.
• Improved performance in segmentation and reassembly (SAR) performance
to 3.2 gigabits per second (Gb/s).
• MultiLink Trunking (MLT)
Physical Desc ription of the Switch Modules
The EtherSpeedII 10/100BASE-T switch module (Figure 1-2) consists of a
printed circuit board with a metal module faceplate. The switch module includes
captive retaini ng scr ews and inserter/extrac tor l eve rs on the top and bottom of th e
front panel.

Each switch module occupies one slot in a Centillion 50/100 chassis. In a
Centillion 100 chassis, you can install a maximum of either:
• Five EtherSpeedII switch modules and one master control processor
(MCP) switch module
• Four EtherSpeedII switch modules and two MCP switch modules
In a Centillion 50 cha ssi s, you can install a maximu m of t wo EtherSpeedII switch
modules and one MCP switch module.
Note: See Appendix B, “Cables and Connectors,” for more information about
wiring and pin assignments.
