3 Installing a Switch
On a mounting screw of the chassis of the 3Com series switches, there is a seal labeled. You need to
keep it intact before asking the agent to maintain the switch. You need to get the permission of the local
agent before you can open the chassis. Otherwise, you will be responsible for irreversible damages
caused by your operations.
