NETGEAR XS708T Hardware Installation Guide

Table 5.Troubleshooting chart (Continued)
Possible SolutionPossible CauseSymptom
Break the loop by making sure that only one path
exists from any networked device to any other
networked device. After you connect to the switch
web management interface, you can configure the
Spanning Tree Protocol (STP) to prevent network
loops.
A network loop (redundant path)
was created.
Combined speed and activity
LED is blinking continously on
all connected ports and the
network is disabled.
Remove the unit from the stack. Use the web
management interface to configure the unit as a
stackable unit, with combo links used as the stacking
ports.
The stacking ports of the new
unit are configured differently
from the stack, or the unit is
configured as a standalone unit.
A unit is linked to a stack but
does not join the stack.
Additional Troubleshooting Suggestions
If the suggestions in the troubleshooting chart do not resolve the problem, see the following troubleshooting
suggestions:
• Network adapter cards. Make sure that the network adapters that are installed in the computers are
in working condition and the software driver was installed.
• Configuration. If problems occur after you alter the network configuration, restore the original connections
and determine the problem by implementing the new changes, one step at a time. Make sure that cable
distances, repeater limits, and other physical aspects of the installation do not exceed the Ethernet
limitations.
• Switch integrity. If necessary, verify the integrity of the switch by resetting it.To reset the switch,
disconnect the AC power from the switch and then reconnect the AC power. If the problem continues,
contact NETGEAR technical support. For more information, visit the support website at
support.netgear.com.
• Autonegotiation.The RJ-45 ports negotiate the correct duplex mode, speed, and flow control if the
device at the other end of the link supports autonegotiation. If the device does not support autonegotiation,
the switch determines only the speed correctly, and the duplex mode defaults to half-duplex.
The Gigabit Ethernet ports negotiate speed, duplex mode, and flow control if the attached device supports
autonegotiation.
