Power Manager 2 Serial WORK

The Power Manager (PowerMgr) allows an app to perform certain OS- and power-related actions on the device. These include rebooting or performing an OS update, resetting the device to a factory-fresh state or putting the device into Sleep mode. On some devices, such as the VC8x vehicle-mounted computer and similarly equipped Zebra devices, PowerMgr also can control device heaters and perform actions based on ignition status of vehicle-mounted computers and similarly equipped Zebra devices. PowerMgr performs only actions; it currently supports no queries other than to determine the version of the CSP that implements PowerMgr itself.

On Android devices, Sleep mode turns off the device display screen and places some subsystems into low-power states. Depending on device configuration settings, certain apps and/or subsystems such as Wi-Fi and Cellular might remain active.

This is the On/Off switch for Doze Mode energy saving features on the device. When Doze Mode is enabled, only apps specifically added to the "exemption whitelist" can prevent the device from entering this low-power state. Apps are added to the exemption whitelist using the App Manager CSP.

Used to control the button-presses that wake the device from suspend mode. Devices by default wake only when the power button is pressed. Enabling this parameter (option 1) adds as wake-up sources the push-to-talk (PTT) button (on the left side of the device), scan buttons and any other button listed in the "Wake-up Sources" page in the device Settings panel (varies by device). To control individual buttons, see the Wake-up Individual Action parameter (not supported on TC20/TC25 devices).

Used to select an individual device button to allow or prevent the device from waking from power-saving modes when the button (if so equipped) is pressed. Use this parameter when selecting an Action using the Wake-up Individual Action parameter.

The serial managementconnector (labeled SER MGT) is an RJ-45 connectorthat can be accessed from the rear panel. This port is the defaultconnection to the server. Use this port only forserver management.

If you need to connect to the SER MGT port using a cable witheither a DB-9 or a DB-25 connector, follow the pin descriptionsin the tables to create a crossover adapter appropriate for yourserial connection.

Frustration over these limitations led to significant advancements in the second generation of serial consoles, or Gen 2. With Gen 2 serial consoles, admins get more control, added security features, and expanded automation capabilities.

For instance, most Gen 2 consoles offer management functionality for third-party devices. These serial consoles also have some built-in security features like Trusted Platform Module (TPM) and frequently support advanced authentication methods like AD/LDAP, Kerberos, and RADIUS. Gen 2 serial consoles also allow for greater automation using Python scripts, APIs, and zero touch provisioning (ZTP).

While Gen 2 serial consoles offer more multi-vendor support than their extremely limited predecessors, they still fall short of true vendor neutrality. For instance, managing third-party and legacy devices often requires expensive adapters or complicated configuration tweaks. Many Gen 2 serial consoles also lack support for Zero Trust integrations such as SAML 2.0 (e.g., Okta, Ping, DUO), making it impossible to completely secure your out-of-band network.

Gen 1 serial consoles provide remote, out-of-band management of multiple devices using CLI commands and scripts over a serial connection. Gen 2 evolved to incorporate more devices, more security features, and more automation capabilities. However, the serial console needed to develop even further to handle the needs of a modern enterprise network.

This control is delivered via high-speed OOB (such as a 5G/4G cellular SIM card), giving you 24/7 remote access to critical enterprise infrastructure, even during an ISP outage. Plus, Gen 3 serial consoles use centralized cloud management, which means engineers can manage and troubleshoot remote infrastructure from anywhere, anytime.

A Gen 3 serial console is based on an open architecture, x86 OS, that supports integrations with your choice of infrastructure solutions, cloud services, and automation toolkits. It also includes flexible port configurations and legacy pinouts to control a variety of devices, such as PDUs, IPMI devices, and environmental monitoring sensors.

A Gen 3 console includes robust onboard security features, which reduces the risk of an attacker using a stolen serial console to access your management network (and ultimately, your production systems and data). Its open architecture also enables integration with zero trust security controls and providers.

The open architecture of a Gen 3 serial console makes it possible to integrate with your choice of infrastructure automation and orchestration tools, or directly host VMs and Docker containers so you can run your own tools. With a Gen 3 serial console, you can use solutions like Ansible, Chef, Puppet, or Kubernetes to automate deployments. You can also use any API you want to automate any workload you need to, no matter how complex.

With a Gen 3 serial console, you can create a fully-automated network environment. This allows engineers to work more efficiently and reduces the risk of human error causing an outage or security breach.

A Gen 3 serial console, like the Nodegrid Serial Console Plus (NSCP), gives you complete remote control over every component of your network infrastructure, regardless of location or manufacturer. Nodegrid also secures your OOB management network using zero trust security best practices and comprehensive onboard features. Finally, the Gen 3 NSCP allows you to automate whatever tools you want to use, so you can efficiently manage a complex enterprise network without sacrificing speed, security, or control.

This IC is a protection IC for lithium-ion / lithium polymer rechargeable batteries, which includes high-accuracy voltage detection circuits and delay circuits. It is suitable for protecting 2-serial-cell lithium-ion / lithium polymer rechargeable battery packs from overcharge, overdischarge, and overcurrent. Use of an external overcurrent detection resistor enables this IC to provide high-accuracy overcurrent protection with less impact from temperature changes. The S-82B2A Series has an input pin for charge-discharge control signal (CTL pin), allowing for charge-discharge control with an external signal. The S-82B2B Series has an input pin for power-saving signal (PS pin), allowing for reduction of current consumption by using an external signal to start the power-saving function.

If the first two methods did not work for you, you can disable the Selective Suspend feature. However, be aware that when the Selective Suspend feature is disabled, all USB host controller drivers (and therefore all USB ports and connected USB devices) in the system are affected. Therefore, your computer cannot suspend any USB devices that are connected to it, and the USB devices can continue to use power while connected to the computer. Additionally, the Allow the computer to turn off this device to save power check box does not appear on the Power Management tab for the USB root hub.You can disable the USB Selective Suspend feature by editing the registry. The USB device may become unresponsive because of a race condition in the Selective Suspend feature. The Selective Suspend feature suspends the USB device to efficiently maintain battery power by enabling the computer to turn off the USB device. However, sometimes this feature may not correctly wake up the USB device. Therefore, the USB device is unresponsive when you try to use it. You might want to disable this feature for server products where power management is not important or required. Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

The Opengear CM7100 is a feature-rich console server that simplifies out-of-band management for your network, server and power infrastructure in data centers and remote sites. Powerful monitoring, diagnostics and remediation features enable efficient recovery from infrastructure fault conditions and maximize uptime. An intuitive dashboard with proactive alerting provides network and IT administrators with real-time status of the core infrastructure.

===============================================Part 1: Overview===============================================HP Power Manager enables you to monitor, manage, and control powerenvironments through comprehensive control of individual HP UPSs. A familiar browser interface provides secure access to Management Servers anywhere on the network. You can control power failure settings and define UPS load segments to allow for maximum uptime of critical servers.

The Management Server provides both status and shutdown information to the Remote Agent. The Remote Agent runs on a machine and allows the software to gracefully shut down the operating system of that server and run a script during power failure. Install the Remote Agent on any machine that is powered by the UPS and any machine that the software uses to initiate a command. However, it is not necessary to install the Remote Agent on the machine running the Management Server component.

You can configure HP Power Manager to send alert traps to HP Systems Insight Manager and other SNMP management programs. The software can also run as a stand-alone power management system. This flexibility enables you to monitor, manage, and communicate with a UPS through a network port, USB port, or serial port whenever these ports are available as built-in ports or via option cards. To facilitate day-to-day maintenance tasks, the software provides detailed system logs and system diagnostics, including UPS battery checks.
