Installing the Switch

When you ask your sales agent to maintain the switch, you must ensure that the
dismantlement-preventive seal on a mounting screw of the 3Com switch chassis is intact. If you want to
open the chassis, you should contact the agent for permission. Otherwise, you will bear any
consequence resulted from your actions without permission.
