Console server with 48 serial ports

The Opengear CM8148 is a 1U rack-mountable console server providing 48 RJ-45 serial ports for out-of-band management of network infrastructure. It includes 1.95 GB of DDR4 SDRAM and two Gigabit Ethernet ports for resilient LAN connectivity. Two USB ports add local storage or modem options. The unit runs containerised applications and integrates with Lighthouse software for centralised automation.

Suited for data-centre and edge deployments

Network teams managing dense racks of switches, routers and servers gain consolidated serial access with REST API, Docker and Python scripting support. The hardware TPM 2.0 module secures boot and configuration data. Sites needing more than 48 managed devices or 10 GbE uplinks should evaluate higher-density or faster-uplink models in the same series.

Deciding specification: 48 serial ports

The port count is the primary constraint; each managed device consumes one RJ-45 serial connection. Verify that the total number of console ports required matches the 48 available before purchase.

Questions about this item

What network infrastructure must be in place to connect the CM8148 to the management LAN?

The CM8148 provides two RJ-45 ports that operate at 10/100/1000Base-T speeds, so a standard Gigabit Ethernet switch and Cat5e or better cabling are required for each management link.

Can the CM8148 serve as the single out-of-band console for an older rack that mixes 16-port and 32-port console servers?

Yes, the CM8148 supports up to 48 serial ports and the Lighthouse platform can manage 16, 32, 48 and 96 port devices together, letting it consolidate access for the legacy units.

Which indicator confirms the CM8148 has booted its DDR4 memory and is ready for Lighthouse enrollment?

After power-on the front-panel status LED turns solid green once the 1.95 GB DDR4 SDRAM passes self-test and the management firmware is operational, signalling it can be added to Lighthouse.
