Overview
The Radiance Chassis Stacking Line Card is a four-port 10/100Mbps TX
switch that provides a cost-effective solution for situations in which a simple
switching option with few ports is required. When configured for stacking in a
Metrobility chassis, the card eliminates the need for any external equipment.
This means the network administrator has one less piece of networking hardware to manage and monitor.
The Radiance chassis stacking line card is designed to support a stack of up to
four Metrobility chassis, thus enabling communication between the management
card in each chassis. The stacking line card enables up to 126 local ports and up
to 126 remote ports (using Radiance access line cards) to be managed under a
single IP address. This ability provides visibility and remote software control
over the entire stack, along with notification of a problem or failure to the
network administrator.
Each 10/100Mbps Ethernet port supports auto-negotiation of both duplex and
speed, as well as half and full duplex flow control. Additionally, each port
includes automatic cross-over functionality, which eliminates the need for crossover cables, for easier network setup.
The Radiance chassis stacking line card offers the following key features:
• Auto-negotiation to determine the best duplex and speed for data
communications.
• 10/100Mbps speed control.
• Backpressure flow control in half-duplex mode.
• Pause frame flow control in full-duplex mode (configurable through
software only).
• Built-in crossover functionality that eliminates the need for crossover
cables.
•1M bit buffer of built-in memory.
• Full compliance with applicable sections of IEEE 802.3, IEEE 802.3u
and IEEE 802.x standards.
•A non-blocking, high performance switching engine with the ability to
learn up to 1,024 MAC addresses.
• Support for long packets (up to 1518 bytes for un-tagged frames or up
to 1522 bytes for IEEE 802.3ac tagged frames).
4 Overview
Installation Guide
Follow the simple steps outlined in this section to install and start using the
Radiance chassis stacking line card.
NOTE: Electrostatic discharge precautions should be taken when handling any
circuit board. Proper grounding is recommended (i.e., wear a wrist strap).
Unpack the Line Card
Your order has been provided with the safest possible packaging, but
1
shipping damage does occasionally occur. Inspect your card carefully.
If you discover any shipping damage, notify your carrier and follow
their instructions for damage and claims. Save the original shipping
carton if return or storage of the unit is necessary.
Set the Switches
Two sets of DIP switches, located on the back of the circuit board,
2
allow you to select from several modes of operation. These switches
are clearly marked on the printed circuit board.

When setting DIP switches* on SW2, the OPEN position is when the
lever of the switch is pushed up toward the word “OPEN.” The
CLOSED position is when the lever is pushed down toward the board.
On the rocker DIP switch (SW1), the OPEN position is when the
“OPEN” side of the switch is down and the numbered side is up. The
CLOSED position is when the numbered side of the switch is down and
the “OPEN” side is up. See illustration below.

Auto-Negotiation Switch (AN1, AN2, AN3, AN4)
Switch ANx controls the use of auto-negotiation on its associated port
(e.g., AN1 sets auto-negotiation on Port 1). To enable auto-negotiation,
the switch must be OPEN. To disable this function, the switch must be
CLOSED. By default, auto-negotiation is enabled.
When auto-negotiation is enabled on a port, it advertises 10/100Mbps
half/full duplex capabilities. When auto-negotiation is disabled, the
port’s duplex is determined by the FD switch setting, and its speed is
set by its corresponding 100Mx switch.
Speed Switch (100M1, 100M2, 100M3, 100M4)
The 100Mx speed switch controls the speed setting on its associated
port (e.g., 100M2 determines the speed on Port 2). If auto-negotiation is
disabled on a Port x, its speed will be set to one of the following:
• 100Mbps if the 100Mx switch is OPEN. (default)
• 10Mbps if the 100Mx switch is CLOSED.
When auto-negotiation is enabled, the 100Mx switch is ignored.
*DIP switches also can be managed via console commands or with Metrobility’s NetBeacon™ or WebBeacon™
management software. Refer to the
Software Installation & User’s Guide
management information.
Command Line Interface Reference Guide, NetBeacon Element Management
or
WebBeacon Management Software Installation & User’s Guide

6 Installation Guide
Duplex Switch (FD)
Switch FD determines the duplex mode on all ports that have autonegotiation disabled.
• The ports will operate at full duplex if FD is OPEN. (default)
• They will operate at half duplex if FD is CLOSED.
If auto-negotiation is enabled on a port, that port will ignore the FD
switch setting.
For example, if FD is enabled and auto-negotiation is disabled on Ports
1 and 2 and enabled on Ports 3 and 4, then Ports 1 and 2 will operate at
full duplex, while Ports 3 and 4 will ignore the FD switch setting. The
duplex mode for Ports 3 and 4 will be determined through the autonegotiation process.
Half-Duplex Flow Control Switch (HDFL)
For ports operating at half duplex, the Radiance chassis stacking line
card provides an option to enable half-duplex flow control
(backpressure). When half-duplex flow control is activated, the
Radiance card generates a jamming pattern to force a collision on a port
if a buffer cannot be allocated for the port’s incoming packets. Halfduplex flow control is enabled by default (OPEN).
The HDFL switch must be CLOSED to disable half-duplex flow
control on all four ports. The switch must be OPEN to enable HDFL on
all ports.
Radiance Chassis Stacking Line Card 7
The table below displays sample port configurations and the DIP switch
settings used to obtain them. The configuration column gives the autonegotiation, speed and duplex options for each port. By default, all four
ports are set to auto-negotiate.

Full-Duplex Flow Control (FDFL)
Full-duplex flow control is provided as a means of avoiding packet loss during
times of network congestion. With FDFL enabled (default), the Radiance line
card issues a PAUSE frame when there is no buffer space available for incoming
packets. FDFL is configurable through management software* only.
When FDFL is enabled, it is set on all four ports. However, FDFL is applicable
only to a port when the following conditions are met:
• The chassis stacking line card is in full-duplex mode.
• Auto-negotiation is enabled on the port.
• During auto-negotiation, the port’s link partner indicated that it supports
PAUSE frames.

Card
Using a Radiance chassis stacking line card, up to four Metrobility chassis can
be controlled as a single network device with one IP address. Stacking requires
an R502-M management card in the master chassis. One of the ports on the
chassis stacking line card must be connected to Port 2 of the R502-M.
For each additional chassis you want to include in the stack, connect the
Ethernet port of its x501-M or Port 1 of its R502-M management card to one of
the ports on the chassis stacking line card. (See diagram above.) This provides
the communication path between the master R502-M and the network stack.
When configured for a stack, the management card’s secondary LAN IP address
must be a valid Class B address, in accordance with RFC 1597. The network
portion of the IP address must be between 172.16.0.0 and 172.31.0.0. The host
portion of the IP address must be the chassis’ stack position number followed by
the slot number where you have installed the management card.
Example: network 172 . 16 . 1 . 17 host (stack . slot)
Each management card in the stack must be configured for stacking. Refer to the
Command Line Interface Reference Guide for detailed software instructions.
