This model does not appear to have been distributed in the States.
The schematics state the switch is a IC+ IP175C. Pictures show a D-Link DL1005E, which may indeed be a rebranded IP175C or functionally identical. The schematics also state the RAM used as the ICSI IC42S16160-6TG (256Mbit) and the Flash used as the Spansion S29JL064H70TA100 (stated 32Mbit, 64Mbit actual).
