Chapter 3 Troubleshooting At the First Sign of a Problem Perform the following tasks when you first become aware of a problem with the switch: # Make sure the power cord is securely connected and the power voltage is not fluctuating. # Check the data cables for secure connections and make sure the device at the other end of a connection is operational. # Press the Reset button so the switch can run self-diagnostics. Use Omega to run diagnostics and read statistics.
Troubleshooting Network Cabling Problems If you have 100Base-TX (Fast Ethernet), some network problems may be related to exceeding cabling distances. Refer to the standard IEEE 802.3u, Clause 29.3.1.2 on Worst Case Path Delay Value. This document specifies that the collision domain diameter must be within the following limits: # Under 330 ft (100 m) for TX cabling # Under 1331.
AT-3726XL, AT-3716XL, and AT-3714FXL Installation Guide Contacting Technical Support Provide Technical Support with the following information: # Switch model and serial number # Software version number # Description of the problem See Allied Telesyn’s website at www.alliedtelesyn.com for a list of worldwide Allied Telesyn locations.
Troubleshooting How the Switch Reports Problems The switch detects and processes errors as follows: # The LEDs indicate problems with the port and power. Table 3-1 list and describes the switch LEDs. # In a TCP/IP environment, if you have configured the software correctly, the management software triggers an SNMP trap message. As a result, the software then sends traps to alert the network manager when a trigger occurs.
AT-3726XL, AT-3716XL, and AT-3714FXL Installation Guide Common Problems This section lists the common switch problems and the recommended actions to correct these problems. Port Activity LED ON any Port is OFF This may indicate: # A loose data cable. # The device at the other end of the connection is turned OFF. # The port is disabled through the software. Perform the following steps in sequence; you need not proceed to the next step if the problem is resolved: 1. Make sure the data cables are secure. 2.
Troubleshooting Power LED is OFF If there is no power to the switch, it cannot function. A Power LED that is OFF may indicate: # A loose power cord. # Power supply failure, malfunction or loss of power to the power supply. # A power supply voltage is below acceptable levels. # A high switch temperature due to fan failure or ambient temperature extreme. Perform the following steps in sequence; you need not proceed to the next step if the problem is resolved: 1.
AT-3726XL, AT-3716XL, and AT-3714FXL Installation Guide Fault LED is ON This might indicate problems with the network management software, such as: # Unsuccessful software downloads # Loose RS232 interface connection Perform the following steps in sequence; you need not proceed to the next step if the problem is resolved: 1.
