The Eaton 5P 1U battery backup unit we are reviewing today does something different. Specifically, it puts lithium-ion batteries in a rackmount form factor to provide battery backup and true sine wave capabilities. One of the more interesting areas in the data center is becoming, of all things, power. For years this was an area that many did not care about, but changing server power needs are making many re-evaluate rack power and redundancy options. As such, many racks need to figure out how to fit more dense battery backup capacity, and that is pushing the case for lithium-ion batteries. The model we are looking at is the 5P1500R-L but we are just going to call it the Eaton 5P for brevity.
Eaton 5P 5P1500R-L Hardware Overview
As is the custom with STH reviews, we are going to look at the external hardware, then the internal hardware, before we get to management and features. As one will note, we have a bit of a different set for this new series of reviews, this being the first in the set. We are using a Pelican-Hardigg composite rackmount case that we will be using in December for a project, but it looks very cool so it made its way into this batch of photography.
Eaton 5P 5P1500R-L External Hardware Overview
When one gets the Eaton 5P the battery is in the disconnected state. This is common for battery units for shipping. Unlike some other options, this is exposed directly out of box so one does not have to remove panels or do any disassembly before servicing the battery.
One needs to connect the battery at this front terminal location as well as another wire harness.
One that is done, a black cover is placed over the wires to protect this connection.
Finally, we get a blue faceplate that snaps into the middle. On the other side, we will note that there is a LCD screen that displays status information as well as a basic interface for the unit. There is also a power button to power on/off the unit. This solution felt basic but functional and intuitive.
On the rear of the system, we see a lot more going on.
First, and a very important feature is that we get five outlets. There are two labeled groups but also two different colors. The black outlets are designed for the critical equipment. Group 1 outlets and Group 2 outlets are programmable outlet groups.
The green connector is for ROO or RDO control. There is then a USB and a RS232 console port.
Next, we have the fan. We will see that fan again on the internal overview. The power cord is 5-15P cable on this unit for 120V systems. The cable itself is not large. We were slightly surprised this was only a ~6ft <2m cable. It seems like this unit is designed to plug into an upstream PDU.
Finally one will see a black card slot cover. This covers the network car slot. We asked Eaton to send a Network M2 card (not to be confused with the popular M.2 standard for SSDs, WiFi/ Bluetooth radios, LTE modems, AI accelerators and so forth.) This is a proprietary network card that adds network manageability to the system.
Here is the back of this card.
Here is the card being installed into the slot.
Finally, here is the card installed. While the total installation time took under a minute (save for photography time) we just want to make it clear that this is something that is absolutely a high-margin product for Eaton as it is a relatively simple device, and it is also quite costly to add. Still, we wanted to show management functionality.
Next, we are going to get inside the unit.
