Hardware Troubleshooting
This chapter presents troubleshooting procedures for the Cisco Internet Streamer CDS release 2.0
hardware. The following sections show the symptoms, probable causes, and recommended actions for a
variety of problems.
Troubleshooting Ethernet Adapters
If you are having problems with any of your adapters, use the following steps to isolate the problem:
Make sure the power is applied to the system.
Step 1
Verify that the Ethernet cable is of Category 5E quality, or better.
Step 2
Try replacing the cable with a known good cable.
Step 3
Ensure that the switch at the other end of the Ethernet cable is powered up. Verify the LED is on for each
Step 4
switch port that is connected to an adapter.
Do not be alarmed if LED is not lit on a adapter when power is applied to the system. LED illumination
at system startup is dependent on the version of the adapter. All configured adapters should have LED
illumination once the Cisco Content Delivery Service has been started.
Step 5
Verify that the port configuration on the switch. Most scenarios require that the ports be set to
autonegotiation.
As a final troubleshooting technique, it may be necessary to download and run the Adapter Diagnostics
Step 6
from the appropriate adapter vendor.
The on-board adapter used is a Broadcom component. Vault servers also use a single-port 3Com adapter
and dual-port Intel adapters. CDEs use dual-port and quad-port Intel adapters. Driver and diagnostic
utilities are available on each vendor's website.
