HP Jetdirect 620n Print Server

The HP Jetdirect 620n is a plug-in module that adds a single 10/100Base-TX network port to compatible HP printers with EIO slots. It enables small and medium businesses to share those printers across a wired Ethernet network without replacing the print engine. The unit draws only 2 W of power and weighs approximately 3.20 oz.

Installation in EIO slot

The module slides into an available EIO slot on the printer and secures with two captive screws, requiring no tools beyond a screwdriver. A single RJ-45 patch cable connects the server to a 10 or 100 Mbps switch port. The most common issue is inserting the card into a non-EIO expansion bay or forgetting to enable the EIO port in the printer menu after power-up.

Printer compatibility check

Confirm that the target HP printer lists an EIO slot in its specifications and supports the Jetdirect 620n part number J7934A. Verify that your network infrastructure provides 10/100Base-TX twisted-pair cabling and an open switch port. Buyers needing wireless connectivity, multiple network ports or USB printer support should consider other solutions.

Questions about this item

How do I confirm the HP Jetdirect 620n print server is working after installing it in an EIO slot?

The device draws 2 W; when the single RJ-45 port shows link lights and the printer appears on the network at 10/100Base-TX, it is operating correctly.

What comes in the box with the J7934A and what must be purchased separately?

The plug-in module itself is supplied; a twisted-pair Ethernet cable for the RJ-45 connection and a compatible HP printer with an EIO slot are not included.

Which version of the Jetdirect 620n should I choose for a Fast Ethernet network?

The J7934A model provides one 10/100Base-TX port, matching Fast Ethernet requirements; no other capacity or speed variants are offered for this product.
