Overview
The Metrobility R104-11 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 R104 is designed to support a stack of up to four R5000 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 the 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 cross-
over cables, for easier network setup.
The R104 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).

Overview
Installation Guide
Follow the simple steps outlined in this section to install and start using the
R104.
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
shipping damage does occasionally occur. Inspect your card carefully.
1
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,
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 the Metrobility NetBeacon® or WebBeacon™
management software. Refer to the Command Line Interface Reference Guide, NetBeacon Element Management
Software Installation & User’s Guide or WebBeacon Management Software Installation & User’s Guide for software
management information.

Installation Guide
Duplex Switch (FD)
Switch FD determines the duplex mode on all ports that have auto-
negotiation 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 auto-
negotiation process.
Half-Duplex Flow Control Switch (HDFL)
For ports operating at half duplex, the R104 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. Half-duplex 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.
Metrobility 4- port Switch 7
The table below displays sample port configurations and the DIP switch
settings used to obtain them. The configuration column gives the auto-
negotiation, speed and duplex options for each port. By default, all four
ports are set to auto-negotiate.

•
Insert the card into either slot in the R400 or R1000. In the R5000
chassis,any slot excluding slot #17. Make sure the top and bottom
edges of the board are aligned with the top and bottom card guides
in the chassis. Do not force the card into the chassis unnecessarily.
It should slide in easily and evenly.
•
•
Slide the board in until the top and bottom edges of the front panel
are flush and even with the top and bottom edges of the chassis.
To secure the card to the chassis, turn the thumbscrew clockwise
until it is snug. The unit is now properly installed and ready for
connection to the network.
Metrobility 4- port Switch 9
Connect to the Network
To connect the R104 to the network, insert the twisted-pair cables into
the appropriate connectors. Be sure the card is secured to the chassis by
tightening the thumbscrew before making network connections.
4
The R104 provides four shielded RJ-45 connectors that support a
maximum segment length of 100 meters. Use Category 3, 4 or 5 cables
for 10Mbps segments; use only Category 5 or 5E cables for 100Mbps
segments.
Insert your connectors as shown below. Once power is applied to the
card, correct connectivity can be verified via the link (LK) LED, if an
active device is connected to the remote end of the cable.

LED Indicators
The R104 provides several LEDs for the visible verification of unit status and
proper functionality. These LEDs can assist in troubleshooting and with overall
network diagnosis and management. There are separate link/speed and activity/
duplex indicators for each port.
After power is applied to the card, verify correct connectivity via the LK LEDs.

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 R104 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.
*Refer to the Command Line Interface Reference Guide, NetBeacon Element Management Software Installation & User’s
