Powering On The Switch; Verifying Port Status; Verifying System Operation - Alcatel OmniStack 8008 Getting Started Manual

Powering On the Switch

1. Plug the power cord into the power socket on the rear of the switch, and the other
end into a power outlet. (If you have purchased a redundant power supply, plug it into
the "DC INPUT" receptacle on the rear of the switch.)
2. Check the LED marked Power on the front panel to see if it is on. The unit will
automatically select the setting that matches the connected input voltage. Therefore,
no additional adjustments are necessary when connecting it to any input voltage
within the range marked on the rear panel.
3. The switch performs a self-diagnostic test upon power-on. (Note that this test takes
about 10 seconds to complete.)
Note:
The unit supports a "hot remove" feature which permits you to connect or disconnect
fiber cables without powering off the switch and without disrupting the operation of the
devices attached to the switch.

Verifying Port Status

Check each connection by viewing the port indicators shown in the following table.

Verifying System Operation

Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any device is properly connected to the switch, the Link indicator
will light up for the corresponding port. If the Link indicator fails to light when you connect
a device to the switch, check the following items:
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.
• See if your cable is functioning properly by using it for another port and attached device
that displays valid indications when connected to the network.
• Be sure not to exceed the maximum length for the type and rating of fiber cable you are
using. Refer to the table on the preceding page.
