IBM ATM OC-3c manual Post-Installation Checks, Connecting a cable to the ATM Port

Connecting a cable to the ATM Port

1Ensure that the cable you wish to connect to the port meets the correct specification. For cable specifications, refer to “ATM Cable Specification” on page C-1.

2Each end of the fiber cable has a transmit (Tx) and receive (Rx) connector. Connect the Rx connector to the port’s Tx socket. Connect the Tx connector to the port’s Rx socket. Do the same at the other end of the connection.

Powering Up the Switch

The Switch does not have an On/Off button, so the only way to power up the Switch is to connect it to the main power supply using a power cable.

Connecting a power supply and safety information is described in the user guide that accompanies your Switch.

Power On Self Test (POST)

When powered up, the Switch and ATM Module enter a Power On Self Test (POST). The type of tests performed depend on how POST has been configured for the Switch. Two types of POST are available:

■Normal POST — a basic confidence check which takes between 10 and 20 seconds to complete, and includes:

■Checksum tests of boot and system areas of Flash memory.

■System memory tests.

■MAC address verification test.

Post-Installation Checks 6-5

■System timer test.

■CAM (Contents Addressable Memory) tests.

■Console Port tests.

■Internal packet forwarding tests.

■Switch and ATM Module ASIC (Application Specific Integrated Circuit) tests.

■Switch and ATM Module ASIC memory tests.

■ATM Module interface tests.

■ATM Module packet forwarding tests.

■Extended POST — more extensive testing which takes between 50 and 225 seconds to complete and includes all of the Normal POST tests plus more extensive system memory and ASIC memory tests.

When a new Switch is powered-up for the first time, it performs a Normal POST, which is the default setting.

If you suspect that there is a problem with your device which has not been detected by the Normal POST, run the Extended POST. Configuring POST is described in the user guide that accompanies your Switch.

The LEDs used to indicate POST failure and other post-installation checks are described in “Post-Installation Checks”.

Post-Installation Checks

This section describes the LEDs and basic checks that you can use to verify your installation, and to ensure that the Switch and ATM Module are operating correctly.
