Appendix B Troubleshooting

This section describes problems that may arise when installing the and how to resolve these issue. This section
includes the following topics:

•

Problem Solving

— Provides information about problem management with DES-3252P.

•

Troubleshooting Solutions

— Provides a list of troubleshooting issues and solutions for using DES-3252P.

Problem Solving

Problem management includes isolating problems, quantifying the problems, and then applying the solution.
When a problem is detected, the exact nature of the problem must be determined. This includes how the problem
is detected, and what are the possible causes of the problem. With the problem known, the effect of the problem is
recorded with all known results from the problem. Once the problem is quantified, the solution is applied. Solutions
are found either in this chapter, or through customer support. If no solution is found in this chapter, contact Cus-
tomer Support.

Troubleshooting Solutions

Listed below are some possible troubleshooting problems and solutions. These error messages include:

•

Cannot connect to management using RS-232 serial connection

•

Cannot connect to switch management using Telnet, HTTP, SNMP, etc.

•

Self-test exceeds 15 seconds

•

No connection is established and the port LED is on

•

Device is in a reboot loop

•

No connection and the port LED is off

•

Add and Edit pages do not open.

•

Lost password.

P r o b l e m s

P o s s i b l e C a u s e

S o l u t i o n

Cannot connect to man-
agement using RS-232
serial connection

Be sure the terminal emulator program is set to VT-
100 compatible, 9600 baud rate, no parity, 8 data bits
and one stop bit
Use the included cable, or be sure that the pin-out
complies with a standard null-modem cable

Cannot connect to
switch management
using Telnet, HTTP,
SNMP, etc.

Be sure the switch has a valid IP address, subnet
mask and default gateway configured
Check that your cable is properly connected with a
valid link light, and that the port has not been dis-
abled
Ensure that your management station is plugged into
the appropriate VLAN to manage the device
If you cannot connect using Telnet or the web, the
maximum number of connections may already be
open. Please try again at a later time.
