Connecting via Console
« on: June 15, 2011, 10:29:16 AM »
I am having issues connecting Nortel Baystack 5510-48T ethernet switches via console cable. I do not have the IP address of the switches so connecting to them that way is not an option. I have read the posts and tried all of the options there but I still cannot get any response from the switch and nothing shows up in the terminal window. I am using hyperterminal with a straight console cable. Any help would be much appreciated.

Have you configured your hyperterminal at 9600 bauds 8N1 ? (no Hw control)

Also does your cable works with another switch? If not, try to crossover RX and TX...

Yes it is configured per the specs in the documentation. I have tried the crossover as well. The cable I am using has worked with other devices so it is a known good cable. I have tried it on all of the nortel switches but it still does not work. Any other ideas?

With a straight-thru cable and your terminal emulator set at 9600-8-N-1 you should get the menu by hitting Ctrl-Y. Short of that you can power cycle the switch and you should see it boot on the console.

Good Luck!

Hi buntone and welcome to the forum,

If 'CNTL-Y' doesn't work, have you tried to reboot the switch/stack so that you can see the boot up details in the console.  If you are not seeing anything in the console when rebooting then your console cable is incorrect?

CheerZ and good luck

You need a straight srial cable for your ERS5510.
As jbfuzier mentioned with 9600 bauds with Data Bits 8, Stop Bits 1 Parity None, Flow Control None.

Try to press Ctrl Y , sometimes you can not see the banner.
It is possible to change the console settings, so maybe the baud rate was configured on your switch to a different value.

If nothing helps you can reset the ERS5510 with the UI Button (white Button with blue Nortel Logo on the left side of the switch front)

Here are the steps you need to do:

Press the UI button and hold it for eight seconds.
The color and status of the Pwr LED turns amber, slow blinking to
indicate that the system will reset in less than three seconds. To stop
the reset, release the UI button.
The color and status of the Pwr LED turns amber, with fast blinking
to indicate that the system will reset in less than one second. To stop
the reset, release the UI button.

Hi buntone,

As a work around:

If you have two Cisco cables and a RJ45 'Balun' you can connect the two Cisco cables together and then you should be able to connect from your laptop to the switch console.  That is what I use  ;D

@Flinstone
Do you know the pinout for the Cisco Cables. I have 2 RJ45-DB9 connectors and I can adjust the pinouts to match.

@Dominik
Does resetting the switch cause it to go through the boot cycle and does network traffic going through it get dropped during the reset?

If you reset your ERS5510 it will boot and all traffic will be stopped for a few minutes until it has booted.

So this is a offtime job.

Hi buntone,

I believe the Cisco console cable pinouts are:

Pin         Signal           Input/Output

1             
2               DTR              Output
3               TxD              Output
4               GnD       
5               GnD
6               RxD              Input
7               DSR              Input
8

CheerZ and good luck

@Flinstone

if you buy a Juniper device you get a very cool RJ45 - DB9 adapter.
I really like these adapters, in fact you don΄t have to carry an extra console cable in your bag, you can simple use your standard patchcord.

from experience I only have good success with the OEM Nortel Console Cables. 

as well, what are you using as a hyperterm client?   I would strongly recommend using TeraTermPro.  you can google for TTpro313, it was the last "Free" version.
puTTY is also very good.

For the Avaya ERS and other devices, I normally use DB-9 to RJ-45 adapters on each end (unless of course the console port of the device is an RJ45, then I just use the correct RJ45 to DB9 at my PC com port.

PC Connector
DB9 (Female) to RJ45

RJ45 ------------> DB 9 (Female)

1 – Blue ----------- Pin 1
2 – Orange --------- Pin 2
3 – Black ---------- Pin 3
4 – Red   ------------ Pin 4
5 – Green ---------- Pin 5
6 – Yellow --------- Pin 6
7 – Brown ---------- Pin 7
8 – White ---------- Pin 8
    (or Gray)          
9 – n/c              Pin 9 - Open


ERS 2500–4500–5500–5600 and older BayStack 350/450/460/470/BPS 2000
Straight Through – 1 to 1, 2 to 2, etc., until 8 to 8.  No connect on 9.  Female end.
(same connector as PC connector)

ERS 8300/8600/8800 
DB9 pin   RJ45 pin
1 -----   n/c
2 -----   3
3 -----   2
4 -----   6
5 -----   5
6 -----   4
7 -----   8
8 -----   7
9   n/c
Female DB9 End.

Notes:
The ERS 2500/4500/5000 switches actually only use pins 2,3 and 5 (TD, RD, Gnd) so if you'd like you can simplify this connector to those three pins only.
You can also use the same connector as the 2500/4500/5000 adapter, if you flip the 8800's DCE/DTE switch next to the console.


Avaya Secure Router Connector
(Note – this is the same pinout for a Cisco console connector.)
RJ45 plugs directly into router, DB9 is the PC end.

DB9 Female to RJ45

RJ45 ---------- DB 9

1 – Blue ------ Pin 8
2 – Orange ---- Pin 6
3 – Black ----- Pin 2
4 – Red   ------- Pin 5 Tie Green and Red from RJ45 (RJ45 pins 4 and 5) together at DB9 pin 5
5 – Green ----- Pin 5 note above - DB9 pin 5 has both RJ45 4 and 5 on it
6 – Yellow ---- Pin 3
7 – Brown ----- Pin 4
8 – White ----- Pin 7
9 – n/c         Pin 9 - Open

New switches coming from Avaya this fall and beyond will use RJ45 console ports, and reportedly will use the same pinout as the Secure Router and as Cisco.

I've been using HyperTerm PE with good results.  I know a lot of people who use TeraTerm and SecureCRT as well, and those appear to work well with Avaya console ports.

Yes, resetting the switch causes it to reboot.  That's actually the command normally used to tell it to reboot.  Traffic definitely is affected (dropped) while the switch is rebooting.
