1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a Transition Networks’ pocket
switch. A working knowledge of local area network (LAN) operations,
including familiarity with communications protocols used on
interconnected LANs, is assumed.
Transition Networks’ Pocket Switches
Transition Networks’ pocket switches (E-PSW-TX-02 and E-PSW-FX-02)
provide a smooth network migration from legacy Ethernet™ 10BASE-T
to Fast Ethernet 100BASE-TX or 100BASE-FX, supporting increasing
network demands through incremental upgrades to existing network
investments.
Features
• Supports a full Ethernet segment on each port
• Adheres to current and emerging IEEE802.3 and IEEE802.3u
Ethernet standards
• Provides two ports with selectable 10BASE-T or 100BASE-TX
• E-PSW-FX-02 provides one port with selectable 100BASE-FX
• Supports full- or half-duplex operation on both ports
• Provides selectable auto-negotiation for detecting and adapting
to line speed/operation mode of attached device on each port
• Provides wire-speed switching for same-speed transfers
• Provides packet buffers for high performance
• Supports self-learning of MAC addresses

The sole purpose of this remedy shall be provided the customer with the replacement or
repair of non-conforming goods in the manner described in this Warranty statement. This
exclusive remedy shall not be deemed to have failed of its essential purpose so long as TN is

or the expense of repairs made outside of its factory, except when made with TN’s prior
written consent. Additionally, Transition Networks reserves the right to charge for all testing
and shipping incurred, if after testing, a return is classified as “No Problem Found”.
TN’s total liability in connection with the products and their installation to all persons and
from all causes in the aggregate, whether in contract, tort, or strict liability, shall not exceed

processing.
• The item(s) may be shipped by the customer or the distributor.
• Transition Networks will repair or replace the unit, at TN’s discretion, and cover the
cost of the return freight to the distributor or to the customer, whichever requested
the RMA number.
If the item(s) was received more than five years ago, or if the item(s) is no longer covered by
warranty for other reasons, then:
• Call the distributor or contact TN.
• Request a Material Repair Authorization number (MRA).
• Ship the item(s), prepaid, in the original packaging to Transition Networks at the
above address.
• Include the MRA number on the outside of the carton add/or on the Packing List.
• Include a copy of the MRA form.
• Include a copy of the original invoice or packing list (if possible) to expedite processing.
• Only the customer (end-user) may send the items(s) to TN.
• TN will contact the customer after the item(s) have been received, inspected, and a
cost estimate of the repair determined.
• The repair charges may be billed, with customer’s approval, though the distributor, or
on a prepaid or C.O.D. basis directly to the customer. The charges will include the
cost of shipping.
The return authorization numbers are valid only for 90 days from the date issued.

The Evolving Ethernet Network
Installing one Transition Networks’ pocket switch alone improves
network performance. Installing additional Fast Ethernet equipment
(and, optionally, installing additional Transition Networks’ pocket
switches) can optimize network performance.
A network evolution from legacy Ethernet to legacy Ethernet and Fast
Ethernet that is based entirely on the Transition Networks’ E-PSW-FX-02
pocket switch might be:
