The direct-through or cross network cable has the function of auto-identification, so the  five 
classes of direct-through/cross network cables can be used to connect other  Ethernet devices.

3.3  Checkup After Installation

Before electrically starting up the switch, perform the following checkups after the  switch is instal
led:

• If the switch is installed on the cabinet, check whether the installation point  between the cabi

net and the switch is strong. If the switch is installed on the desk,  check whether there is eno
ugh space for the switch to discharge its heat and  whether the desk is stable.

• Check whether the connected power meets the power requirements of the  switch.
• Check whether the grounding line is correctly connected.
• Check whether the switch is correctly connected to other terminal devices.
