I'm not familiar with Summit switches (I have tried Cisco switches)
So if your switch has Console port (usually they need either serial cable or RJ45)
Im gonna assume it's RJ45. Your RJ45 cable ends with serial end just like in this picture:
You plug the RJ45 into the switch. The other end needs to go to your computer. If you're computer has serial port input, great.. If not, then you will need a good quality serial to USB cable.
Go to your device manager on your computer and find out what COM number you have.
Take a look at my attachment.
In my computer it's COM9, open putty and follow the attachment picture.

Do you need a RJ45 to DB9 cable to begin configuring a switch in PuTTY?
Better DB-9 to RJ-45 solutions?

You'll also need a USB to serial adapter if you computer has no serial interface. Choose serial in putty and 9600 baud, 8 data bits, no parity and 1 stop bit (96008n1).
You can only use ssh/telnet if you device has an IP address and is configured correctly.
I'm currently trying to setup and configure a Phoenix Contact 2207 Ethernet switch. I have an Ethernet (RJ45) cable to USB adapter plugged into my laptop. When I try the Serial option in PuTTY I'm always met with the "unable to open serial port." In my Device Manager there's only the Intel Active Management Technology option for a COM. The info and advice I've read only includes using a Rollover cable (RJ45 to DB9) and if you don't have a serial port on your PC you can use a DB9 to USB cable to finish the connection. Is a DB9 needed somewhere in this equation? I'd assume I could just have an Ethernet to USB adapter for this to work.
I'm just wondering how to get over this initial problem to begin configuring the IP addresses of the switch ports.
Sidenote: I have the RJ45 (Ethernet) cable plugged in a normal port on the switch. As far as I can tell there's no primary "contact port".
Hope this doesn't come off as too ignorant.
Thank you.
Probably like many, I've got a stack of these DIY DB-9 to RJ-45 adapters for console access because every manufacturer is special and needs their own unique pinout to accomplish basic serial communication.... Worked well enough with my Toughbook CF-19, but need another serial extension cable to fit in the flush DB-9 ports on things like my Dell Latitude Rugged laptop and CF-20 tablet.
Cleaning/reorganizing my tool bag today, looking at these things, and curious if there's a better mousetrap out there? I know could just pick up a generic premolded RJ45 female to DB-9 adapter, then make custom CAT5 cables to match, but that would take up a lot more room in the tool bag too.
Would be great if someone made something similar to these custom adapters but with a molded DB-9 end, or maybe something like a RJ-45 coupler that could be repinned, so I wouldn't have to carry a bunch of bulky cables.
I ordered a DB9 to RJ45 converter so I can connect to old switches with DB9 female connector.
I ordered two, but I failed the pin-out on the first one. And can't pull back plugs once they're pushed in. Does anyone know the correct scheme to get this working with an old HP 3500 switch to be specific?

No. Ethernet ports can't transmit or receive RS-232 signals.
If your laptop has a traditional DB9 RS-232 serial port, use that with the appropriate serial cable. If it doesn't, use a USB to RS-232 serial adapter.
If you have something like this item, then it is merely a pinout adapter and not a serial/ethernet device.
You could use one of these on each end of a RJ45 cable to make a serial cable. That serial cable could run through structured cable installed inside a wall or similar, but it cannot run through an ethernet switch or vlan.
I am attempting to control a device with RS232 commands.
The device has a control box that accepts RJ45 cable.
I am sending my commands via a Global Cache iTach WF2SL device which has a DB9 serial port.
I am attempting to connect the two devices using a Cat-6 T-568B cable, and a RJ45 to DB9 adapter.
The WF2SL pinout uses 2 - RX, 3 - TX, and 5 - Ground.
The control box expects what is in the image below:
Screen-Pinout462×336 35.3 KB
The adapter has the following pinout definitions:
Adapter Diagram831×771 47.9 KB
I’ve been trying to research this to determine the correct pinout but have become pretty much completely confused at this point.
I have ensured that the WF2SL is configured with the correct baud rate and additional settings.
I have tried quite a few different combinations of pinouts with no success.
Would anyone be able to dumb this down for me, and help me get the right pinout on the adapter, using the Cat-6 cable I have, to work with what the device is expecting?
Thanks in advance.
2 to 3, 3 to 2 and 5 to 5.
Update
As I originally predicted, the wiring is proprietary and the flow control signals are a mess. @SofaKng has reversed engineered the official cable and produced this table (reproduced here):
RJ45 pin, DB9 pin (female)

2 6 + 8

You missed a key detail. Their RJ-45 patch cable is null modem wired. That means it is reversed. You got all of your pairs backwards (you connected TX to TX, RX to RX, etc...)
Assuming you are using a straight-through patch cable...
- as you indicated that you are with your comment "standard TIA-568B"
- you must use TIA-568B ordering on both ends of your patch cable
...it goes this way:
Device Signal, RJ-45 Pin#, DB9 Pin#, PC Signal
----------------------------------------------
> DTR 1 --- 6 DSR
> GND 2 --- 5 GND
> RTS 3 --- 8 CTS
> TxD 4 --- 2 RXD
> RxD 5 --- 3 TXD
> DSR 6 --- 4 DTR
> GND 7 --- 5 GND <-- note: repeats, bussed to device #2
> CTS 8 --- 7 RTS
> RI 9 --- 9 RI <-- doesn't actually fit in an RJ-45 (only 8 signals), probably safe to ignore if I read their diagram correctly
The DB9 on a PC is pinned out this way (see figure). Note how it is null-modem reversed from the table listing you provided. That's because their RJ-45 cable is null-modem reversed to cancel it out. Tricky and silly, but that's how they chose to implement it.
Some other thoughts...
Actually, I noticed from tracing in the diagram that they do some very strange stuff with the flow-control signals. For example, they short CTS and DSR on the PC side, but not on the other side. They route RTS on the PC side to DSR on the device side. And other weirdness.
This may be bad documentation, but I suspect they have implemented custom firmware/software that makes use of the flow-control signals in non-standard ways as a means of ensuring that you only buy and use their cables and adapters.
I would suggest that you make two half cables. On one end go RJ-45 to unterminated wire and the other go DB9F to unterminated wire. Then you can twist your way through all of these weird configurations until you get it right. I would start with my suggested mapping. If that doesn't work, report back and I'll give you my mapping for all of their weirdness in the flow-control lines.
Good luck! =)
I ended up ordering a premade cable and adapter from Pacific Custom Cables and they worked so I checked the pin-out of the RJ45 (null-modem) to DB9.
Based on their pin-out, I made a new cable (crimped RJ45 on one end, soldered DB9 female on the other end) and here is the working pin-out:
RJ45 pin, DB9 pin (female)
----------------------------
1 1
2 6 + 8
3 2
4 5
5 5
6 3
7 4
8 7
I don't understand why that is the pin-out but that's what works and the pin-out from "official" cables and adapter.
