Introduction
1.1 Getting Started
1.1.1 Inspecting the Package and Product
Examine the shipping container for obvious damage prior to installing this product; notify
the carrier of any damage that you believe occurred during shipment or delivery. Inspect
the contents of this package for any signs of damage and ensure that the items listed
below are included.
This package should contain:
• MultiLink ML3000 Ethernet Switch, base unit (configured with user-selected port
module options installed)
• Set of metal “ears” for 19-inch rack mounting
• Installation and user guide (this manual)
Remove the items from the shipping container. Be sure to keep the shipping container
should you need to re-ship the unit at a later date. To validate the product warranty, please
complete and return the enclosed product registration card to GE Multilin as soon as
possible.
In the event there are items missing or damaged, contact the party from whom you
purchased the product. If the unit needs to be returned, please use the original shipping
container if possible. Refer to Troubleshooting on page 4–6, for specific return procedures.
