Magnum Router Hardware Problems
Magnum Router Power-up Self Test Problems
Symptom: No red OK LED Indicator
Solution: Magnum Router Module is not seated properly in Marathon base unit. Power off
Marathon base unit and check for proper installation. See chapter 4 for Magnum Router Module
hardware installation instructions.
Symptom: All LED’s are blinking rapidly.
Solution: Hardware failure. Unit must be repaired. Contact your authorized Magnum /
Marathon Dealer for a replacement .
Frame Relay Link Does Not Come Up
Symptom: WAN port LED is red or off, indicating that no valid frame relay LMI packets have
been exchanged.
Solution:
• Magnum Router Module port physical configuration is wrong for attached device.
If connecting CSU/DSU, Magnum Router Module port should be DTE. If directly
connecting to FRAD, Router or bridge (DTE), Magnum Router Module port should be
DCE, with baud rate set to match capability of connected DTE device.
• Magnum Router Module port Link Type configuration is wrong for attached device.
Verify that the Magnum Router Module port Link Type is set to the correct type for your
application. Refer to chapter 9 for sample configurations.
• Wrong cable for application, or defective cable.
Verify that correct cable is being used (check part number and compare the cable to the
Magnum Router Cable Kits described in chapter 2). Only cables purchased from the
manufacturer / distributor should be used with this product.
• Carrier problem (if public frame relay carrier is involved)
If Magnum Router Module configuration is correct and correct cable is being used and
properly secured, contact the carrier for assistance.
Symptom: WAN port LED is red and never goes to green.
Solution: Annex-D or LMI mismatch between Magnum Router Module and the carrier.
Make sure that both Magnum Router Module WAN port and the carrier are using the same link
management type.
