AT-MR415T and AT-MR815T Installation Guide

Is The Link On Lamp Lighted?

The LINK ON lamps on the front of the repeater will light when a proper

connection between the corresponding 10Base-T port and the equipment

connected to it is established. If this lamp is not lighted, check for the

problems listed below and make corrections as necessary.

1. Problem 1:

The UTP (twisted pair) cable has been cut, damaged, or is the wrong type

of cable.

❑ Solution:

Try making the connection with a different cable. Be sure you are using an

undamaged cable of the correct type.

2. Problem 2:

Connected equipment is not turned on or not operating properly.

❑ Solution:

Check the connected equipment (computer, another repeater, etc.) and turn

on the power.

3. Problem 3:

The MDI MDI-X toggle switch of the AT-MR415T/AT-MR815T Micro

Repeater is on the wrong setting.

❑ Solution 3:

When using the cascade port of the AT-MR415T/AT-MR815T Micro

Repeater, the switch should be set to MDI; otherwise, the switch should be

in the MDI-X position. When cascading two AT-MR415T/AT-MR815T

Micro Repeaters, the unit using the cascade port should have the switch set

to MDI, while the other unit should have its switch set to MDI-X.

When port 4 of the AT-MR415T or port 8 of the AT-MR815T are not

connected to another repeater, but are used to connect to a computer or

other equipment, the MDI MDI-X toggle switch should be set to MDI-X.
