Trademark Notice

All registered trademarks and trademarks are the property of their respective owners.

TN’s total liability in connection with the products and installation thereof to all persons and from all causes in the aggregate whether in contract, tort, or strict liability shall not exceed the amount paid to TN for the product directly related to the alleged damage. However, in no event shall TN have any liability to a customer or any third party with respect to a product manufactured in accordance with customer’s specifications.

C. Return Procedure

Before TN item(s) can be returned, a Credit Return Authorization (CRA), Return Material Authorization (RMA), or Material Repair Authorization (MRA)number must be obtained from TRANSITION Networks (TN) or the distributor of origin.

Locate the serial number(s) of the item(s) to be returned. From the item serial number, TN or the distributor will verify the return status and provide the appropriate number to the End User. The three types of return numbers are listed below:

A Credit Return Authorization (CRA) number can only be requested from your distributor. This CRA number will only be issued to distributors for item(s) within 90 days from the original ship date. Under no circumstances will a CRA number be issued directly to the End User. The return item(s) must be shipped freight prepaid, by the End User or the Distributor to TN.

A Return Material Authorization (RMA) number can be requested from TN or your distributor. This RMA number is only issued for item(s) after 90 days from the original ship date but prior to the expiration of the warranty period. The return item(s) must be shipped freight prepaid, by the End User or Distributor, to the TN address below:

TRANSITION Networks Inc.

6475 City West Parkway

Eden Prairie, MN 55344 USA

TRANSITION Networks will repair or replace the unit, at its discretion, and cover the cost of the return freight to the distributor or End User who was issued the RMA number.

A Material Repair Authorization (MRA) number can be requested from TN or your distributor. This MRA number is only issued for out-of-warranty item(s). The return item(s) must be shipped freight prepaid, by the End User, to the TN address above. The sender will be contacted by TN after the item(s) have been received, inspected, and a cost estimate of the repair has been determined. The repair charges may be billed, with approval, through your distributor or prepaid/C.O.D. basis through the End User. In either case, charges will include freight, both ways, and repair charges.

The return authorization number is only valid for 60 days from the date of issuance. Please list this number on the outside of the carton and/or packing list. Include a copy of the original invoice or packing slip to expedite processing.

D. Restocking Fee

All returns for credit must be received in the same condition as originally shipped. If TN determines that a returned product is damaged due to improper packaging or if the item is functional and returned because of customer error, inability to use, etc., TN reserves the right to charge a minimum 15% ($10.00 minimum per item) restocking fee, the payment of which is a condition precedent to the repair and/or return of the product.

Monitoring Port/Indicator LEDs

Each of the eight twisted pair ports has an associated LED:

steady green

data traffic is active on link

flashing green port has been partitioned.

2. SITE CONSIDERATIONS

The site for the LANMaster T8 8-Port Ethernet Hub w/SIC Slot must provide:

AC power outlet for each LANMaster T8 8-Port Ethernet Hub w/SIC Slot

Adequate ventilation

Standard environmental conditions

Isolation from electrical noise, including radio transmitters and broadband amplifiers, motors, high power electrical lines, or fluorescent light fixtures.

Additionally:

The twisted pair cables should not run in the same conduit with power line cables.

Phone lines should be separated from data cables.

Flat or “silver satin” wires should not be used.

If using Slide-in Card (SIC) connection between LANMaster T8 Hubs, the maximum cable distances are:

Fiber Optic

2000 meters

10Base5

500 meters

10Base2

185 meters

10BaseT

100 meters

And:

Since the LANMaster T8 8-Port Ethernet Hub w/SIC Slot functions as an Ethernet repeater, the entire LANMaster T8 8-Port Ethernet Hub w/SIC Slot installation should comply with the IEEE Ethernet 802.3 specification.

RJ-45 connected cables should be configured as crossover or straight through according to installation requirements.

Ensuring Compliance with 5-Segment Rule

To conform to the Ethernet 802.3 specification, when connecting LANMaster T8 Hubs, the transmission path between any two Data Terminating Equipment (DTE) devices can consist of no more than five segments. NOTE: A segment is the cable connection between cable interfaces in an Ethernet LAN.

To assign segment numbers to cable connections:

1.Determine the two terminals in the network which are separated by the greatest number of segments.

2.Assign a segment path between the terminals by labeling the cable connected to one of the terminals “segment 1” and the segment connected to the other terminal “segment n” (n = total number of segments and must be 5 or fewer).

3.To verify that no segment paths contain more than n segments, assign segment paths and numbers to all other terminals.

Fiber Optic Connector/10BaseFL Connection

The fiber optic card (E-FRL-SIC) provides one set of transmit (TX) and receive (RX) connectors to fiber optic cable.

The redundant fiber optic card (E-FL/RED-SIC) provides a back-up fiber optic connection by providing two sets of transmit (TX) and receive (RX) connectors to fiber optic cable.

up to 2000 meters

Ensuring Correct 10BaseT Configuration

The 10BaseT cable and RJ-45 connectors for Hub to Terminal connections must be configured as straight through. The 10BaseT cable and RJ-45 connectors for Hub to Hub connections must be configured as crossover. NOTE: When installing the LANMaster T8 Hub using the MDI port, a crossover cable is not needed. The MDI switch can be used to change the straight through configuration to crossover at port 8.
