HPE Aruba Instant On 1960 24G 2XGT 2SFP+ Switch Internal Hardware Overview
Inside the switch, we see a lot of empty space. There is the switch PCB, a small power supply, and a lot of unused space. These switches also come as PoE versions (JL807A) so having the additional space is likely for the larger power supplies used in PoE switches. It also keeps the size consistent between models.
The 24-port version of this switch is fanless, whereas the 48-port version had a fan. The lack of fans means that we do not have the noise. Also, in theory, this means that there are no moving components to fail.
The vent that was on top of the switch is directly over the largest heatsinks inside the chassis.
Here is the view from the opposite angle.
The power supply is a relatively small unit. We will again note it is not hot-swappable nor is it redundant. This is a SMB edge switch so that is common.
The main PCB has ports, switch chips, and a management processor.
The heatsink closest to the PSU likely has the management processor (an 800MHz single core Arm Cortex-A9) as that has the DRAM package next to it. These heatsinks we did not want to risk removing since this switch has to go back to HPE.
Still, we will give you another view of the heatsink fins inside the switch. We wish we had the PoE version as that would have more going on internally.
Next, let us get to the management aspects of the switch because that is certainly a high point.
