is there any firmware upgrade for allowing cuncurrent telnet sessions to the APC ?

No. The interface has been designed to allow only 1 Telnet session at a time. The reasoning is to prevent conflicting changed happening concurrently.

Hi Bill,

   thanks for the response, you mean to say there is no way to access concurrently this APC,

if that is the case then how it is enabled on other models like AP8941.

Thanks,

The AP8941 has a second generation network card embedded. The AP7921 has generation 1 embedded card.

Hi Surendra,

AP7921 is based on our Network Management Card 1 (NMC1) technology which only allows (1) connection to each interface. There is no way to change this.

AP8941 is based on NMC2 technology which does now allow multiple user sessions of any type - web, telnet, SSH, etc except for local serial connection.

Any NMC1 device will operate the same way and any NMC2 based device will also operate the same as described above.

Side note: We created AP7921B which is AP7921B with an NMC2 inside of it so it is possible on that model to do multiple telnet sessions.
