Quad-Port SFP+ Expansion for Aruba 3810M and 2930M

This plug-in module adds four SFP+ ports to compatible Aruba 3810M and 2930M switches. It supports 100M, 1G and 10G link speeds for flexible uplinks or downlinks. The expansion module targets network administrators who need extra fibre or direct-attach connectivity in data centres, corporate offices or small-to-mid-size businesses.

Plug-In Form Factor with Four SFP+ Cages

The module slides into an open expansion slot on the host switch without tools or cabling to the chassis. Each of the four cages accepts standard SFP+ transceivers or DAC cables for multi-mode, single-mode or copper links. Hot-swap capability lets technicians add or replace optics while the switch remains powered and passing traffic.

Verify Switch Model and Available Expansion Slot

Confirm the chassis is an Aruba 3810M or 2930M with a free module bay before purchase. Check that the switch firmware supports this part number and that the power budget covers the additional transceivers you plan to install. This module does not function in other switch families or as a standalone device.
