Setup Guide
1. Unpacking and Initial Inspection
Carefully remove the Mitel 5330e IP Phone and all accessories from the packaging. Verify that all components are present: the phone unit, handset, coiled handset cord, and Ethernet cable.
2. Connecting the Phone
- Connect the Handset: Connect one end of the coiled handset cord to the handset and the other end to the handset port located on the left side of the phone base.
- Connect to Network: Connect one end of the Ethernet cable to the LAN port on the back of the phone. Connect the other end to an active Ethernet port on your network switch or router. The Mitel 5330e supports Power over Ethernet (PoE), which means the phone can receive power directly through the Ethernet cable if your network infrastructure supports it, eliminating the need for a separate power adapter.
- Optional Power Connection: If your network does not support PoE, an optional Mitel-approved power adapter (sold separately) is required. Connect the power adapter to the power port on the back of the phone and plug it into a standard electrical outlet.
