Network Flexibility
The Transition Networks’ pocket switch can assist a network
administrator in maintaining existing resources as the network evolves
from shared legacy 10Mb/s Ethernet to switched 100Mb/s Fast Ethernet
because a pocket switch can function as :
• A 2-port bridge in the legacy 10BASE-T environment
• A connection between the legacy 10BASE-T environment and
the evolving Fast Ethernet 100BASE-TX /100BASE-FX
environment
• A 2-port bridge in the Fast Ethernet 100BASE-TX /100BASE-FX
environment.
Standards-Based
Transition Networks’ pocket switches are designed and built according
to accepted and evolving Ethernet standards. The IEEE 802.3 Carrier
Sense Multiple Access with Collision Detection (CSMA/CD) Access
Method and Physical Layer Specifications, which applies to 10BASE-T,
has been adopted by the International Organization for Standardization
(ISO). IEEE 802.3u is the extension of IEEE 802.3 to 100BASE-X.
Protocol Compatible
As devices functioning on the OSI MAC layer, Transition Networks’
pocket switches are protocol independent and therefore totally
compatible with IEEE 802.3, IEEE 802.3u, TCP/IP, NetWare, DECnet
and XNS protocols. No software installation is required. Protocol
compatibility allows cost-effective network migration with maximum
use of existing equipment, cabling infrastructure, network management
systems, and MIS expertise.
Pocket Switch Operation
The Transition Networks’ pocket switch is an Ethernet network device
integrated into the legacy Ethernet network that adapts selectively to the
Fast Ethernet network by examining all incoming data packet frames for
the destination address and quickly determining the appropriate output
port and mode (half-duplex or full-duplex) for the packet.
5. MAINTENANCE
WARNING: DO NOT, UNDER ANY CIRCUMSTANCES, attempt to
repair the Transition Networks’ pocket switch. Failure to observe this
warning could result in personal injury or death from electrical shock.
NOTE: Failure to observe the above warning will immediately void the
warranty.
Fault Isolation
1. Is the power LED on the switch illuminated?
NO
• Is the power adapter the proper type of voltage and cycle
frequency for the AC outlet?
• Is the power adapter properly installed in the switch and in
the outlet?
• Contact Technical Support.
YES
• Proceed to step 2.
2. Is the Link LED illuminated on a port with twisted-pair installed?
NO
• Check UTP cables for proper connection/pin assignment.
• Contact Technical Support.
YES
• Proceed to step 3.
3. Is the Link LED illuminated on a port with fiber installed?
NO
• Check fiber cables for proper connection.
• Verify that TX and RX cables are connected to RX and TX
ports, respectively, on 100BASE-FX device.
