Opengear CM8148-10G 48-Port Smart Console Server, Dual 10GbE SFP+, Dual GbE, ARM Cortex-A9 1.6GHz, 2GB RAM, 16GB eMMC, Dual AC, 1U Rackmount

With 48 Cisco-pinout RJ45 RS-232 serial ports, dual 10GbE SFP+ uplinks, and a 1.6GHz dual-core ARM Cortex-A9 processor, the Opengear CM8148-10G delivers uncompromising out-of-band management for dense infrastructure. This 1U rackmount console server centralizes access to routers, switches, firewalls, and servers—even when the primary network is down.

Overview

The CM8148-10G is engineered for data centers, remote sites, and edge deployments that demand always-on management. Its 48 serial ports connect directly to console ports of critical equipment using Cisco straight-through pinout, eliminating the need for adapters. Two 10 Gigabit SFP+ ports provide high-speed out-of-band connectivity, while two Gigabit RJ45 ports offer flexible management network options. The dual-core ARM Cortex-A9 processor, paired with 2GB DDR3 RAM and 16GB eMMC flash, ensures responsive performance for concurrent sessions and local logging.

What stands out

• High-density serial connectivity: 48 RJ45 RS-232 ports with Cisco straight-through pinout—no adapters needed for most Cisco gear.
• Dual 10GbE SFP+ uplinks: future-proof bandwidth for out-of-band management and data collection.
• Redundant dual internal AC power supplies: no external bricks, no single point of failure.
• Advanced security: FIPS 140-2 validated cryptography, TPM 2.0, and Secure Boot protect the management plane.
• Smart OOB™ and Lighthouse integration: automate failover, cellular failover (with optional modem), and centralized management across thousands of devices.
