2.3.2 Replacing a failed power supply
To replace a failed power supply slide the lever to the right and pull out the power supply. Push the new power
supply all the way in until the lever latches.
2.4 Connecting to a Host
To connect the A54812-SW switch to a host, follow these steps:
1. Attach one end of a cable to the 10/100 Ethernet connector (RJ-45 connector) on the connector side of the
switch to gain access to the SDM utility, which you use to configure and manage the switch.
—
Use a standard RJ-45 cable to connect to an external Ethernet hub or switch.
—
Use a crossover RJ-45 cable to connect directly to a computer.
2. Plug the other end of the RJ-45 cable into an Ethernet hub, a switch, or a computer. Start the SDM utility on the
host. By default, the switch supports the configuration parameters listed in the following table, which provides
a point-to-point (non-network) Ethernet connection between the switch and the host.
WARNING
Provide the A54812-SW switch with an AC-protective earth-ground connection. Never
defeat the ground conductor or operate the A54812-SW switch without a suitably
installed ground conductor.
The following table lists the switch configuration defaults.
