settings, alarms, and SNMP).

System I/O - the status and configuration of the input and output connectors on the rear of the 

main CPU card (e.g., communication settings, code out, J1, J2, and J3).

•

Subsystem - configuration of the option cards located in the option bays

Under Subsystem, the XLi names CPU-aware option cards to the right of the option bay where they are 
located. Non-CPU aware cards can be present and fully operational in an option bay, but are not shown 
in the web interface. For more information, see 

.

Only option bays with CPU-aware option cards will have active links. Clicking the link of an unpopulated 
or non-existent option bay simply refreshes the web page. 

When clicking on links, allow each page to load before clicking another link. Clicking links too quickly 
may cause the Login page to appear.

When submitting changes, only click the Submit Changes button once. Wait for the web page to load 
before navigating away from the page or submitting another change. 

To log out, click the Logout button located in the upper left corner of the page.

If the user closes the browser without logging out, a new session will not be available until the XLi closes 
the inactive session after 30 minutes. 

Notes for specific pages in the web interface:

•

Mode setting and applies the changes, the GPS C/A Receiver goes through several states 
before attaining the user-specified mode.

•

Change Login Page: To change the Operator name, but not the password, leave the password 

field blank and submit the change.

XLi IEEE 1588 clock.
