Alcatel-Lucent OmniStack 6148 48-port stackable managed Ethernet switch.
The Alcatel-Lucent OmniStack 6148 (1AF03140ABAA) is a stackable Ethernet switch base unit offering 48 x 10/100Base-TX ports plus two expansion slots for uplink or stacking modules, housed in a rack-mountable managed-switch chassis. Part of Alcatel(-Lucent)’s OmniStack 6000 series, the 6148 was aimed at wiring-closet and access-layer deployments needing high port density for desktop and VoIP endpoint connectivity, with support for VLANs, port trunking and console-based management.
Its stacking architecture allowed multiple OmniStack 6000-series units to be combined into a single logically managed switch, simplifying operations for larger sites while keeping per-switch cost down. The OmniStack 6148 was deployed through the 2000s and 2010s across enterprise and carrier access networks, and remains in service in legacy environments where it continues to be supported with genuine spares.
Tech-Star supplies this switch as a tested, like-for-like replacement for operators and IT teams maintaining existing OmniStack 6000-series infrastructure. Tech-Star (UK-based, shipped worldwide) – get in touch to confirm firmware and stacking compatibility with your setup.
