TimeKeeper Grandmaster quick start

Quick setup

Connect a GPS antenna to the female SMA GPS (Grandmaster generation 2) or BNC (Grandmaster generation 1) connector on the back of the device. The GPS receiver provides 5v DC to the antenna.

Connect a network cable to the first RJ45 ethernet port (far left when facing the back of the unit) and navigate with a web browser to 192.168.1.1. You can log in with account “admin” and password “timekeeper” (Note: In earlier shipped Grandmasters the default password was “fsmlabs”) to configure the network ports, TimeKeeper mode and options. Change the admin user’s default password immediately for security, please. If this is an upgrade and you have been using previous versions of the grandmaster GUI interface, it is recommended that you force a full page reload (Ctrl-Shift-R on many browsers). This will make sure your browser loads the latest web interface from the grandmaster and provides all of the latest features.

To change network interface addresses navigate to the “Configuration” tab and then “Networking” subtab, select the options you would like then click “Save Network changes” and then “Restart Network” to apply the updates. The changes will take a moment to apply after which you can reconnect to the newly configured address.

By default (and as shipped) the grandmaster does not support SSH access for configuration. That can be enabled through the web interface, however. Please see below for details on enabling additional access methods.

The device will then synchronize with the GPS and once done will answer NTP queries and provide PTPv2 service on the default domain (domain 0) on all network interfaces. The GPS startup process can take up to 15 minutes in some cases. You can monitor progress on initialization via the “Status” tab in the web GUI.

No further configuration of the server should be necessary.

Shipped network configuration

Each network port is configured with a unique static IP address when shipped. eth0 is configured for 192.168.1.1, eth1 for 192.168.2.1 and so on. This includes optional 10G SFP+ ports/25G SFP28 which are eth5 (192.168.6.1) and eth6 (192.168.7.1) and so on.

Please note, the TimeKeeper Grandmaster does not support having multiple network interfaces on the same subnet or multipath routing.

The System Management/IPMI interface can be logged into with the default username “ADMIN”, password “ADMIN”.

Factory reset

The factory settings for network configuration and time service settings can be restored with a “factory reset”. To perform the factory reset you must be able to log into the device via RS232 console (using 57600 baud, 8n1) or through a connected keyboard/monitor. Log in with the account “factoryreset” and the password “timekeeper”. Note: In earlier versions of TimeKeeper the password was “fsmlabs”. Once that is done you will be asked to confirm twice that you wish to perform a factory reset. Once that is done the settings will be restored and the system will reboot. Once booted the system is back to factory original settings.
