Overcome Network Outages 和 Disruptions 与 Back-up Connectivity
当网络瘫痪时, 或者远端设备离线, IT administrators need a way to connect to field hardware 和 restore normal operation. The best way to do that is 与 secure out-of-b和 management.
Out-of-b和 (OOB) management is a method of remotely controlling 和 managing critical IT assets 和 network equipment using a secure connection through a secondary interface that is physically separate from the primary network connection. This enables administrators to gain control even during infrastructure faults.
Digi solutions enable out-of-b和 (OOB) management 和 network resilience for a range of use cases
Digi offers a number of Out-of-B和 solutions, including 十大买球网站之一's Network Resilience Platform ——以 聪明的 OOB™ management 和 NetOps 控制台服务器 - 和 a full range of 数码控制台服务器和路由器 together 与 数码网络远程管理®:
How Does 带外管理 Work?
Out-of-b和 management is typically enabled through a serial console port, 如rs - 232, 哪一个 provides a comm和 line interface for troubleshooting routers, 服务器, 开关, 电源控制器, storage devices 和 other equipment. This enables administrators to configure, 重新启动, 和 reset devices if the primary network becomes unavailable.
Out-of-b和 management is especially useful for IT teams that need to manage large numbers of locations at scale, where physical access to each individual device is nearly impossible. This technology serves as a valuable component of any network disaster recovery plan. As networks are increasingly distributed, the need for out-of-b和 management is even more important.
Out-of-B和 Data Center Management
Critical IT assets are found across all modern enterprises, including traditional data center, regional distribution centers 和 branch locations. While the scenario is constant, the major variable is the number of devices at each location. Larger locations often have redundant wireline WAN connections; the ability to reach these locations can be severely compromised in the case of a network incident. Cellular connectivity in every location ensures the greatest chance for rapid recovery.
Remote Site Resilient Network Management
Several factors distinguish the most effective approach to out-of-b和 management. One of these is wireless connectivity. Many organizations provide back-up for primary copper or fiber connections 与 a secondary wired line to regional distribution centers 和 branch locations. However, back-up lines can be vulnerable to the same hazards that can affect a primary wired line.
The lines share the same conduits 和 may even connect to the same service providers. Wireless technologies bypass much of the wireline infrastructure, making wireless a more reliable choice for connectivity. 除了, 与 a cellular connection in pass-through mode, there’s no need to replace an existing router, 防火墙或SD-WAN设备.

With wireless out-of-b和 management in place, most device failures can be effectively addressed by a remote connection, avoiding costly onsite visits by service technicians. 与此同时, cellular failover maintains seamless connectivity 与 critical equipment when the primary network is offline, 减少停机时间.
Networks are increasingly deploying IT infrastructure in remote locations. As data is collected closer to its source, there’s a greater need to monitor 和 manage the equipment from a central location. Troubleshooting 和 remediation at the edge, through the use of out-of-b和 management, empowers administrators to address problems quickly, before they result in a catastrophic network failure.
Managing Infrastructure from Anywhere
The flexibility to access 和 manage devices from anywhere is a fundamental capability of out-of-b和 management. 数码控制台服务器等 数码连接®IT 4 和 十大买球网站之一 弹性网关, help enable continuous network uptime by functioning as an always-on cellular out-of-b和 gateway in remote locations such as branch offices, 亭, retail stores 和 distributed infrastructure.
除了, 数码网络远程管理 — Digi’s centralized security 和 management platform — provides a unique form of out-of-b和 management through its integrated console terminal. Administrators can perform out-of-b和 management 与 virtually any enterprise hardware through a serial connection using a combination of Remote Manager 和 Digi cellular products running the Digi Accelerated Linux (DAL) operating system. 数码网络远程管理 allows devices to avoid using static IP addresses, providing greater security 和 management flexibility. An SMS emergency recovery mechanism enables administrators to 重新启动 remote Digi devices even if they aren't currently transmitting TCP/IP data.
When using a console server from the Digi Connect IT family for out-of-b和 management through 数码网络远程管理, the architecture looks similar to the diagram above.
For Businesses that Dem和 Always-on Connectivity
For administrators managing critical IT infrastructure in remote locations, 24/7 connectivity is a business necessity. But connectivity can be impacted by many things, 从天气事件, 配置失败, 人类的错误, or even distributed denial-of-service (DDoS) attacks. 不管原因是十大正规买球app推荐, an unplanned outage that disrupts the ability to manage 和 run a business is costly. Out-of-b和 management is a requirement for every network manager’s toolkit.
