AS5300 AUX/MODEM cabling

I'm trying to confirm the cabling and connectors required to connect a modem to the AUX port of an AS5300. The Cisco online documentation indicates that I should use an RJ45-RJ45 rollover cable and an RJ45-DB25 converter.

Is the rollover cable the same cable used to connect a laptop to the console port (robin's egg blue)?

AUX Port RJ-45-to-RJ-45 Rollover RJ-45-to-DB-25 Modem

Signal RJ-45 Pin RJ-45 Pin DB-25 Pin Signal

RTS 1 8 4 RTS

DTR 2 7 20 DTR

TxD 3 6 3 TxD

GND 4 5 7 GND

GND 5 4 7 GND

RxD 6 3 2 RxD

DSR 7 2 8 DCD

CTS 8 1 5 CTS

Thank You,

Dan

Re: AS5300 AUX/MODEM cabling

In a rolled cable, the colored wires at one end of the cable are in the reverse sequence of the colored wires at the other end of the cable.....it's the same cable that's used for console connection.

Re: AS5300 AUX/MODEM cabling

Thanks again, Mak. I found a similar page on Cisco's website that indicated that this was an RJ45-RJ45 rolled (rollover) cable. In additon, it requiresa RJ45 Female to DB-25 Male (modem) connector.

Regards,

Dan
