Desk phone for hybrid workspaces

The HP Poly Edge E400 is a corded VoIP desktop phone built for hot-desking and home-office use. It delivers enterprise-grade audio with Poly HD Voice, NoiseBlockAI and Acoustic Fence technologies. Microban antimicrobial product protection reduces bacterial growth on surfaces for the life of the device. Two Gigabit Ethernet ports with PoE support provide network connectivity and PC pass-through.

Dual-display layout replaces single-screen models

A main 3.5” colour display with surround-light status indicator offers eight line keys supporting 32 lines. An integrated 2.4” secondary display adds six more line keys for speed-dial access. The jump is worth it when users need simultaneous visibility of more than eight lines or want dedicated speed-dial screens without scrolling through menus on a single display.

Check PoE infrastructure and line-count needs

Verify that your network switches supply Power over Ethernet on the ports where the phone will connect. Confirm that 14 physical line keys (eight on the primary display, six on the secondary) match the number of extensions or shared lines each user manages. Ensure the two RJ45 ports satisfy both the LAN uplink and the downstream PC passthrough requirement.

Questions about this item

Does the HP Poly Edge E400 require a separate power adapter, or can it run from the two RJ45 ports?

The phone uses two high-speed GigE PoE Ethernet ports, so it draws power from the network cable and does not need an external adapter.

What is the correct way to connect a PC through the phone, and what mistake should I avoid?

Plug the incoming network cable into the LAN port, then run a second cable from the PC port to your computer; do not swap the two ports or the passthrough will not work.

Will the Microban antimicrobial protection on the handset and housing wear off and need reapplication?

The protection is built into the plastic for the life of the product and actively reduces bacterial growth 24/7 without any reapplication.
