5.2 Troubleshooting

Use these guidelines to troubleshoot various aspects of NetXpress LX/CM-30 operation.
5.2.1

Channel Module Addition

Before adding a channel module to your shelf, you might want to switch the module to REMOTE
control so that you can use the NetXpress LX/CM-30 Web interface to configure the module's settings.
Insert the module adapter first, and then insert the channel module. All Intraplex channel modules can
be hot-inserted; the modules can be installed while the shelf is operating.
Warning! It is possible to insert the channel module improperly, causing damage to the module
being installed and other installed modules. When inserting the module, make sure the
white ejector tab is next to the floor of the chassis on a 3RU shelf or to the right of the
chassis on a 1RU shelf.
1. Insert the module adapter in the slot on the back panel behind the one you have selected for the
new channel module.
2. Insert the channel module into the front of the shelf. Once it is inserted, the NetXpress LX/CM-30
system detects the module automatically.
3. On the NetXpress LX Home page, click Open on the displayed module to review and, if the
module is set to REMOTE, to adjust its settings. (Section 4.3.10 – Configure Individual Modules
(TDM Channel Modules) gives additional information.)

Web Browser Interface

5.2.2.1 Page Refresh Problems
If you submit changes to a page and the fields remain unaltered, try clicking the Refresh button in
your browser. If none of the fields change, clear the cache in Internet Explorer (Go to Tools |
Internet Options and, in IE 2007, click Delete at Browsing history or, in earlier versions of IE,
click the Clear History button.) Then, press the Refresh button on the specific NetXpress LX/CM-30
Web interface page.
You can also change the page settings for refresh times in Internet Explorer. In IE 2007, perform
these steps:
1. Go to Tools | Internet Options.
2. At Browsing history on the General tab, click Settings.
3. In IE 2007, at Temporary Internet Files, click the Every time I visit the webpage option.
4. In earlier versions of IE, at Check for newer versions of stored pages, click the Every visit to
the page option.
Note: If you are using a non-IE Web browser, your browser's Help should give instructions on
changing the browser page settings.
5.2.2.2 Route Creation Failures
If you cannot create a route, there is a good chance that the interface does not have an IP address
and correct mask within the network to find the gateway. The new entry must be within the scope of
the interface that is using existing routes. Check the destination IP address and the mask for the route
you are creating. Confirm that the addresses are valid for the network and that it is reachable on the
interface listed on the route. Section 4.3.4.2 – Forwarding Table gives additional information.
