The ServerTech Sentry Power Tower Expansion Module (PTXM) is our exclusive method for linking units on different power circuits together to increase the density of managed outlets per IP address and to managed group outlets on different power circuits.
Each PTXM links to a PTXL, which contains both network and serial interfaces. When linked to a PTXL, the PTXM's power outlets are auto-discovered by the PTXL's firmware, and all available outlets are viewable and controllable through the firmware.
For most data centers, dual-power corded servers and network gear have become the standard. With the PTXL & PTXM solution, each dual-corded device can be grouped and rebooted via a power cycle to that device. First, link the PTXL & PTXM together; the PTXL's firmware interface auto-discovered the PTXM's outlets. Then, create a group name for each dual-corded server and associate the outlets on different power circuits with tat devices (i.e, A1 & B1). Next, when a dual-corded device needs to be rebooted, log in to the PTXL and choose that device's group - a single command to reboot multiple outlets on different power circuits.
An unlimited number of groups can be created between the PTXL & PTXM. Additionally, any combination of outlets between the PTXL & PTXM can be associated with each group.
