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
