I have a new Cisco SG500 switch. It has a serial console port on the back of it rather than the normal RJ45 console port that most Cisco devices have.
Does anyone know why they do not provide an RJ45 console port. Is this a new trend or something ?

Makes it a real nuisance that I cannot connect with my regular serial-USB console cable.

Back in the dark ages of ISDN, some Cisco products used standard DB9 serial. It's no biggie - a standard 'null modem' cable does the job.

I'm not sure how much use the CLI is these devices is. The SG500 is a "budget" layer 2 managed model and does not run IOS.

As Michael said, DB9 predates RJ45 console ports :)

I make sure I always have my USB-RS232 cable, along with a DB9 null modem cable.

I have an SG-300-10P, and while it isn't IOS, it is good enough for most people.

Edit: I've just taken a quick look at mine, and the CLI appears to be very very similar to the Dell Powerconnect switches. Probably the same chipset/OS.

Man you are missing out.

Allied Telesyn (or Allied Telesis/AT) used to have a combination of:

DB9 Male
DB9 Female

Depending on the switch family - WITHIN A GENERATION. So you had to carry 3 serial cables around.

Not to mention the OS changed depending on model and generation.

Man, good times.

But as has been said - this doesn't appear to be an IOS switch - more likely a rebadged Linksys so not surprised. All new gear we've had (2000 and 3000 series and above) are all RJ45.
