LED Indicators and PSU alarms
The LED indicators on the NSG-X200 provide status information for various functions. The following is a list of behaviors for each LED indicator.
- Power LED: Solid green when unit is powered on.
- Hard Disk activity LED: Flashes amber when information is being written to or read from storage.
- Status LED 1: Indicates the status of bootstrapping operation.
- Blinking green: NSG has booted up, but there is no USB and hence no auto-bootstrapping. The installer must execute a one-factor or two-factor bootstrap.
- Solid red: WAN checks failed or proxy not reachable.
- Alternate blinking green and red: WAN check passed, proxy is reachable but auto-bootstrap request rejected by VSD or VSD not reachable.
- Simultaneous blinking green and red:Auto-bootstrap request registered successfully with the VSD and is pending approval by either CSPRoot/Admin.
- Solid green: NSG bootstrapped successfully.
- Status LED 2: Reserved for future use.
The NSG-X200 emits an audible beeping alarm when two power modules are installed and one of the following is true:
- One module had no power input.
- One module has failed.
The power module beeping alarms can be disabled with the PSU alarm suppression button on the rear panel.
Pre-Bootstrapping Functionality
The Nuage bootstrapping solution allows the NSG to securely connect to VSCs, download their service configuration, and connect end users to their services based on pre-defined policies with minimal user interaction. Once the NSG is successfully bootstrapped, it has access to the full feature set provided by the Nuage VSC and VSD.
Some functionality is available to the NSG prior to bootstrapping. Pre-bootstrapping features allow you to perform troubleshooting tests on an NSG that has failed to bootstrap. These features are included as part of the factory software shipped on the NSG.
Refer to the "Bootstrapping" chapter in the Nuage VNS User Guide for more information about bootstrapping and pre-bootstrapping functionality.
- An NSG status webpage is available from the LAN access ports prior to the NSG bootstrapping. The status page is available here.
- The status presents real-time information on bootstrapping status, WAN check status, mobile connection, IP configuration, storage, memory, and SSH.
- An uplink configuration script can be executed via CLI to allow you to configure a single WAN uplink prior to bootstrapping. This allows you to perform WAN connectivity checks without having to bootstrap the NSG.
- Once the WAN uplink is configured, you can perform a ping, tracepath, route, or NSLookup command to verify WAN connectivity.
- NSG info can be viewed by a Nuage user from the CLI pre-bootstrap. Run the nsginfo script to see the NSG type, serial number, MAC address, UUID, and other information.
- During NSG bootstrapping, each page in the bootstrapping captive portal includes a Show Advanced Log button. The button expands or collapses a window that shows the logs generated by the NSG during bootstrapping. The window provides a visualization of bootstrapping warnings, errors, and info messages as they are raised in realtime.
- You can download an archive of NSG log files via the NSG bootstrapping captive portal or via the NSG CLI prior to bootstrapping.
- These log files can be useful for troubleshooting if a support team member needs advanced log details about a failed bootstrapping attempt.
- By default, SSH is not enabled on a pre-bootstrapped NSG. You can enable the SSH service for remote access through the NSG console or from the NSG status webpage.
