All SG510s have 2 DIMM slots, but for SG510-A and SG510-B only 1 DIMM slot is populated. The SG510-A and SG510-B memory configuration is as follows:
DIMM slot 1: Empty
DIMM slot 2: 1 x 1GB DIMM.
Versions of SGOS 5.5.11.x prior to 18.104.22.168 expect both memory DIMM slots to be populated and report an error when it is not possible to read from memory DIMM slot number 1. This error does not impact the functionality of the ProxySG in anyway.
To resolve this error please install SGOS 22.214.171.124 or newer.
