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.
