Routing and Switching / Cisco catalyst 2960 Switch
February 22, 2018, 01:34:15 AM
Hi everyone,

I have recently just bought a used Cisco c2960 switch from a parts recycling company and was hoping to use it at home for learning and playing around.
Since I am quite new to it all I dind't realise I needed the rollover cable (RJ45 to DB-9/RS-232) to configure it via the console port. I'm currently a bit lost as to how I can get around this after much googling. I had bought an RJ45-USB adapter as I don't have an RS-232 connector on my PC, and tried setting up a serial connection via putty making sure to set the right paramters such as baud rate at 9600 and use COM1 with Data bits set to 8 Stop bits set to 1, no Parity and Flow control as XON/XOFF.

I have both a crossover ethernet cable and a standard ethernet cable, but would like to know if it is possible to connect to the switch via a USB port. Also I don't have any of the software configurations that may have been set up via the previous user and I have reset the switch (at least I think I have) by holding down the Mode button.
If anyone has any experience/advice on this, that would be greatly appreciated. :)

Hi guys,

Very new to the forums and excited to be a part of a networking minded community!

Anyway, to the point. Over the past 4-5 years I have seemed to have some serious bad luck with routers and modem-routers either dropping connections from the Ethernet ports or completely dying.
Some background info:
The first 2 modem-routers I had were Netgear Wireless-G DG834G both of which gave up working entirely a little over a year from setup. I sent them back under warranty.
Since the last Netgear I lost all faith in that brand so I bought a TP-Link N600, this worked great until it didn't. Unfortunately I lost the receipt so no warranty :( Despite this I bought another TP-Link N600, thinking it may have just been a one-off hardware thing, based on all the great reviews it got. It's currently still going strong, although for some reason I couldn't connect to it via Ethernet for a couple days, that has since resolved itself...
For the router problem I bought a TP-Link Archer C9, this worked fine until all connections were dropped and upon inspection, noticed that all indicator lights were quite dim, so opening it up I found the voltage across the LED's to be around 2.5V which I assume is not its operating voltage and I suspect it may be a symptom of a fault somewhere else. I once again put my trust in TP-Link and bought the same router a year after the previous one and within 6 months all connections were lost again, although the LED's seem to be the same brightness as new.

All of the above routers and modem-routers are located in open environments with no heat traps surrounding them and there is at most 4-5 devices connected to any one of them.

I'm really starting to wonder if this is normal to keep going through routers so often or I'm just really good at picking lemons OR I'm the lemon when it comes to setting up a home network (highly probable).
