TP Port and Cable Installation
⇒
In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of
cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in
10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and
crossed-over (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used.
It means you do not have to tell from them, just plug it.
⇒
Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the
other end is connected to a network-aware device such as a workstation or a
server.
⇒
Repeat the above steps, as needed, for each RJ-45 port to be connected to a
Gigabit 10/100/1000 TP device.
Now, you can start having the switch in operation.

Power On
The switch supports the redundant 100-240 VAC, 50-60 Hz or –48VDC
power supply. The power supply will automatically convert the local AC/DC power
source to DC power. It does not matter whether any connection plugged into the
switch or not when power on, even modules as well. After the power is on, all LED
indicators will light up immediately and then all off except the power LED still keeps
on. This represents a reset of the system.
•
Firmware Loading
After resetting, the bootloader will load the firmware into the memory. It will
take about 30 seconds, after that, the switch will flash all the LED once and
automatically performs self-test and is in ready state.
