Verifying the Installation
When the ATMSpeed/155 module is installed and the cables are connected to the
ports, the module is ready for operation. All connected ports are enabled, unless
they have been disabled by SpeedView. Enabling and disabling ATMSpeed/155
module ports is described in Using SpeedView 3.0 for Windows.
You can verify the installation of an ATMSpeed/155 module by observing the
LEDs on the module while the module is operating and at system startup. This
section describes the ATMSpeed/155 module LEDs and the LED sequence at
startup.
