Προσαρμογέας PoE HPE R8W31A

The HPE R8W31A PoE adapter supplies 48 V power over Ethernet with a maximum output of 15.4 W and supports the IEEE 802.3af standard. Designed for use with select Aruba Instant small business products, this compact midspan injector accepts 100–240 V AC input and carries multiple safety and compliance certifications (CE, FCC, VCI, cUL US, UL GS, EAC). Its small footprint makes it suitable for constrained installation locations.

Advantages

The adapter delivers standard-compliant PoE power (48 V, up to 15.4 W) in a compact form factor, simplifying deployment where dedicated PoE switches are not available. Broad input voltage range (100–240 V) and common safety certifications ensure compatibility with international installations. The device is lightweight and easy to integrate into existing network setups.

Suitable for

• Powering Aruba Instant small business access points and other 802.3af-compatible devices
• Adding PoE capability to non-PoE network ports
• Small office or branch installations with limited space

How to use

Connect the adapter to an AC mains outlet (100–240 V), then link the Ethernet output to the powered device or switch port. Ensure the connected device supports IEEE 802.3af PoE. Follow standard safety practices when installing near other network equipment and verify that the device being powered does not require more than 15.4 W.

Recommendations

Use this PoE adapter to provide power to single Aruba Instant or other 802.3af devices where a PoE switch is not available; avoid using it with devices that require higher-power PoE standards (e.g., 802.3at/af+). Install in a ventilated area and confirm cable and connector integrity before powering devices.
