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 crossover 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).
4 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
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.
