Remove the tape from the circuit-breaker switch handle, and move the
circuit-breaker handle to the on position.
To comply with the intrabuilding lightning surge requirements, intrabuilding
wiring must be shielded, and the shield for the wiring must be grounded at both
ends.
The Catalyst 3550-24-DC switch is suitable only for intrabuilding or nonexposed
wiring connections.
As the switch powers on, it begins POST, a series of eight tests that run
automatically to ensure that the switch functions properly. When the switch
begins POST, the port LEDs turn green. The System LED flashes green, and the
RPS LED turns off. As each test runs, the port LEDs, starting with number 1, turn
off. The remaining port LEDs each turn off in sequence as the system completes
a test.
When POST completes successfully, the port LEDs return to the status mode
display, showing that the switch is operational. If a test fails, the port LED
associated with the test turns amber, and the system LED turns amber. If POST
fails, see Chapter 3, "Troubleshooting,"
The switch 10/100 and 10/100/1000 ports configure themselves to operate at the
speed of attached devices. If the attached ports do not support autonegotiation,
you can explicitly set the speed and duplex parameters. Connecting devices that
do not autonegotiate or that have their speed and duplex parameters manually set
can reduce performance or result in no linkage.
