3. Plug in the bridge and verify
1. Plug the power cord into the bridge's power socket and into an ac power source. Note
that the bridge does not have a power switch; the bridge is powered on when the power
cord is plugged in.
The HP 10:10 LAN Bridge MB has a power supply that automatically adjusts to any ac
power source that provides between 90 and 240 volts. No voltage range setting is
necessary.
2. Check the LEDs on the bridge's back panel.
– The Pwr (power) LED is ON.
– The Self-Test LED is OFF; it stays ON only while self-test is running (appoximately
30 seconds).
– The Fault and Net Fail LEDs are OFF.
– The Receive and Transmit LEDs will begin flashing if there is any traffic on the
network.
If the LED pattern is different, refer to "Diagnosing With the LEDs" in chapter 5,
"Troubleshooting".
Note
One of the features of the HP 10:10 LAN Bridge MB is that during self-test and
initialization it checks the status of the attached networks.
As a result of this feature, though, the bridge will not pass self-test unless viable
networks are attached to the bridge ports or the ports are terminated with
loopback connectors (described in appendix A).
