1-8 Overview
Migrating from 10Base-T to
Fast Ethernet
Fast Ethernet (100Base-T) has evolved from standard Ethernet (10Base-T).
Therefore, migrating to Fast Ethernet is fairly simple. Consider the following
three suggestions as you incorporate Fast Ethernet into your network:
■
Purchase dual-speed Network Interface Cards (NICs) from this point
forward. These NICs operate at 10 Mb/s or 100 Mb/s, so you can use
them with your 10Base-T repeaters now and continue to use them when
you decide to purchase 100Base-T equipment.
■
Verify that any fiber runs you plan to use at 100 Mb/s meet the distance
limitations discussed in the “Cable Requirements” section in Chapter 2,
“Planning Repeater Installation.”
■
Purchase 100Base-TX repeaters and reconnect the dual-speed NICs to
these repeaters. Interconnect the 10 Mb/s and 100 Mb/s networks using a
server, dual-speed switch, or a router.
Figure 1-7 shows an example of a network configuration that incorporates both
10Base-T and Fast Ethernet equipment, including the 100Base-TX repeater.

Fast Ethernet Repeater Management
The managed 100Base-T repeater (Model 3612) contains a Management
Daughtercard (MDC100), which provides SNMP management through both inband and out-of-band communications. This repeater uses a master/slave
management architecture in conjunction with the repeater hardware to provide
four-group RMON support (Statistics, History, Alarm, and Event) in a stack of
100Base-T repeaters.
In addition to normal repeater operation, all managing repeaters provide inband and out-of-band management via a dedicated local MAC port and the
front panel, DB9, COM port:
■
In-band (or out-of-band via SLIP): SNMP, RMON, Telnet console, and
TFTP download
■
Out-of-band via VT100 interface: Same console as Telnet and firmware
upgrades
You can perform the following operations via a network management
application, such as the HubView Network Management System:
■
Select the backplane
■
Enable or disable ports
■
Enable port intrusion and security
■
Monitor port link status, port partition/enable status, and port statistics
NOTE: The repeater retains most configuration settings when powered down and
automatically re-initializes during the power-up cycle.
For more information about the repeater's management capabilities, see Chapter
4, “Repeater Management.”
Internal DIP Switch
If management is not available for the repeater, you can isolate a repeater's
collision domain from the other repeaters in the stack by setting an internal DIP
switch. This switch is accessible through the Power Supply A or B opening.

1-10 Overview
See Appendix B, “Internal DIP Switch” for information about switch settings.
CAUTION: Remove power from the repeater before you set the DIP
switch.
NOTE: Use the DIP switch only when all other configuration methods are
unsuccessful.
100Base-T Repeater Expansion
Each 100Base-T repeater has an expansion interface that consists of two 100pin connectors (UP and DOWN) on the repeater's back panel. You can achieve
both management and Ethernet expansion by connecting the UP connector of a
lower repeater to the DOWN connector of an upper repeater using a FlexPlane
connector (Part No. 810172-000).

FlexPlane Interconnection
Management Expansion
The FlexPlane includes a management bus that enables one managed repeater
to manage all other unmanaged 100Base-T repeaters in a stack. All internal
stack management is out-of-band so that there is no impact on your network
traffic.

Ethernet Expansion
The FlexPlane connector provides three Fast Ethernet backplane segments that
let you segment a stack of repeaters into three vertical collision domains (Figure
1-9). You can also segment repeaters on an individual basis.

Extending Your Network with
Smart Uplink Modules
The Smart Uplink Module (SUM, Part Nos. 267042-001, 267043-001, and
267045-001) lets you integrate multiple 3512/3612 100Base-T repeaters into a
100Base-T configuration without the usual repeater hop limitations inherent
with Class I repeaters. SUMs use a special buffer to isolate collisions between
segments. In effect, this buffer restarts the repeater count and distance
measurement each time a transmission passes through the SUM. A SUM is up
to 20 times faster than a Fast Ethernet bridge and up to 200 times faster than an
Ethernet bridge.
This enhanced speed allows network transmissions to pass through multiple
SUMs without significantly reducing throughput.
The SUM also provides these features:
■

2-2 Planning Repeater Installation
Electrical Requirements
The electrical requirements for a repeater are as follows:
■
Voltage: 100 to 240 VAC
■
Power: 1.5 (@ 100 VAC) to 0.90A (@ 240 VAC)
■
Frequency: 50 to 60 Hz
CAUTION: The power outlet must be a non-switched, grounded power
source. Do not use a three-to-two pronged adapter at an outlet. Doing so
may result in electrical shock and/or damage to the repeater and will void
your warranty.
NOTE: The repeater comes with a shielded AC power cord. If you lose or damage
the supplied shielded power cord, replace it with a shielded power cord that meets
local regulatory requirements to ensure emissions compliance.
Spatial Requirements
The repeater's dimensions (HxWxD) are 1.75 x 17.00 x 13.65 inches (4.5 x 43.6
x 35 cm).
You can interconnect up to five repeaters in one stack. Be sure to allow at least
2 inches (5.1 centimeters) on each side of the repeater for proper air circulation
and cable connections.
Cable Requirements
This section defines the requirements for cable used to connect the RJ-45 ports,
the Smart Uplink port, and the serial COM port on repeater.
