I/O Ports
Difficulty Plugging in an Ethernet Cable
Note: The Ethernet port on an iMac (Flat Panel) has a special mechanism to prevent modem cables from
accidentally being inserted. In some cases, this mechanism can cause difficulty when attempting to plug in
an Ethernet cable.
1. Verify that you are plugging into the Ethernet port. See graphic below.
2. Notice that the port has two metal tabs (circled below) which prohibit the use of a modem cable.
3. When inserting the Ethernet cable, try holding the cable at a slight angle and wiggle the connector to get
past the metal tabs.
4. Once the connector has passed the metal tabs it should slide in with no further difficulty.
