Section 5 – Testing & Troubleshooting

5.1 Testing

You can use these diagnostics tests to check your NetXpress LX/CM-30 operation:
● General status test – Assure the system power is operational and there are no modules
registering major alarms.
● Ping test – Send echo requests to each multiplexer to test communication.
● Multiplexer-to-multiplexer communication test – Assure you can create and activate streams
between NetXpress LX multiplexers and the streams send packets error-free.
● CM-30 alarm test – Assure there are no current alarms or alarm history.

General Status Test

You can start with a very basic test: check module status by looking at indicator lights. You can check
indicator lights on either the physical chassis or through the Web interface.
5.1.1.1 Physical Indicator Lights
When the system is powered up, the POWER and NORMAL green indicator lights on the front panel
should be on, and the ALERT and ALARM lights should be off (Figure 5-1).
Figure 5-1. NetXpress LX 3RU Multiplexer – Front View, Closed
If the POWER light is off, check that power has been wired to the system. If the unit is AC-powered,
the AC line cord should be plugged in. If the unit is DC-powered, the external power fuse should be
inserted.
If the NORMAL light is off and either the ALERT (minor alarm) light or ALARM (major alarm) light is on,
check the Faults | Current Alarms page on the Web interface. If you cannot access the system,
check the CM-30 module WAN and LAN indicator lights for network connectivity.
5.1.1.2 Web Interface Indicator Lights
After you access the Web interface (Section 4.2.1), you can check system status information on the
NetXpress LX Home page (Figure 5-2).
