2.4 Using the CSU Front Panel to Verify System Operation
Once the connected modems and CRS-500 have been properly configured, make sure the
CRS-500 is operating fault-free. Make sure that the modems’ “Online” and “Bridge” functions
and status are operating as intended.
1. Complete all modem and switch installation and configuration tasks before
proceeding.
2. Refer to the pertinent modem’s Installation and Operation Manual for
detailed operational information
Via the CSU’s front panel operations (i.e., M&C accomplished by observing the LED Indicator
