Contrary to the General/typical RBS6000 family, the RBS6402 is a small cell. It is not modular and doesn't consist of modules like DUL/RUS. It doesn't have any CPRI connections. It can support up to three radio modules and comes in a varity of different LTE bands.

variants / part numbers

there are plenty of different variants out there:

this is a standard SFP connector, you can use any gigabit ethernet compatible MM or SM SFP module on it


Use a LTPoE++ capable 90W PoE injector here


This is a standard 3.5mm terminal block. You can e.g. use a Wurth Electronic 691361100002 or Phoenix contact MC 1,5/2-ST-3,5


The fan connector has two pins with +5V and two pins with GND. You can use a Molex 43025-0408 part to mate it. This is just the housing, you will need crimp contacts and matching crimp tool, or you use pre-crimped wires like Molex 79758-0010.

The two top pins (near the latch) are GND, while the two bottom pins (near the enclosure) are +5V.


The GPS connector is an 8-pin "Industrial Mini I/O" connector, supposedly matching crimp connectors are
  • Amphenol ‎10137239-0011LF‎
  • TE ‎2069250-1‎

See NCD 901 601 GPS Receiver for the Ericsson original GPS receiver


the device has 2 'cluster' of 4 led each

Cluster LED Color Function
3GPP ! red alarm - becomes solid while pressing reset for 30sec and goes off when done, should be off
'checkmark' green should be solid green when provisioning is ok. blinks while not ready
'eye' yellow should be off, blinks while not ready yet
'globe' green should be solid green when provisioning is ok

factory reset button

On the back (connector) side, in one corner there is a black rubber cap over some kind of high density debug connector. You have to remove that rubber cap completely (not just the connector part) and will notice a pushbutton underneath the location where the rubber lid is fixed to the enclosure.
