The two simms inside... the upper is 72 pins and the lower is 80 pins. Not sure which is used for what though.

Specifications

This is the hardware:

CPU

No idea - Could be a sparc derivitive, given the SPARC chip on the board.

Console and serial cable

The front panel console port is a bog standard RS232 socket. You need a 9 pin serial cable with a male end for your computer, and a female end for the switch. Minicom is known to work fine. Port speeds should be 9600 N81.

Can you save the mp4.img from a omnistack 4024 by tftp or serial line, to restore the imag to another omnistack 4024 with the file system totally erased?

How can I reset the switch to Factory Defaults?

I advise unplugging all ethernet cables from your switch before doing this.

  1. You need to connect via a console serial cable with suitable terminal software running
  2. Power on the switch
  3. Hit any key when prompted by boot process about 10 seconds after power-up to get to boot/diagnostic menu
  4. Enter c
  5. Press enter (which accepts the defaults) until line displays: "Boot Flags :0xb"
  6. Enter 0x1000
  7. Press enter until back at the "[Boot]:" prompt
  8. Enter S to save settings (thats a capital S)
  9. Enter @ to boot

The Switch has reset to factory defaults.

What is the default username and password?

Login: admin
Password: switch

How to change the password?

Log in as admin and enter pw admin then choose a better password.

What is the default IP address for an Alcatel Omnistack switch?

192.168.10.1 and the default netmast is 255.255.255.0

Where can I find configuration documentation (instructions) for an Omnistack 4024C?

No idea - thats why I compiled all my findings on one page for other users. If you know something I don't please tell me.

How do you change the switch's IP address from the default 192.168.10.1?

  • You need to connect via a console serial cable with suitable terminal software running
  • Power on the switch
  • Hit any key when prompted by boot process about 10 seconds after power-up to get to boot/diagnostic menu
  • Enter c
  • Press enter (which accepts the defaults) until line displays: "Boot Options:"
  • Enter dvip:hostname,ip,netmask,broadcast
    that is dvip:myswitch,192.168.66.77,255.255.255.248,192.168.66.64
  • Press enter until back at the "[Boot]:" prompt
  • Enter S to save settings (thats a capital S)
  • Enter @ to boot

    The Switch will now have a new IP. Note - any errors on saving may imply the flash storage has died. Also, if the settings aren't sticking while the unit is power off then that suggests flash storage problems.

    I did a factory reset and all my ports are coming up as half-duplex. How do I fix it??

    Log into the switch via serial or telnet, and type 10/100vc to see the config. Set all ports to auto negotiate with 10/100cfg 3/ and 10/100cfg 2/ for both ports on slot 2. If you then want to change individual ports back to half duplex or 10 Mbit then 10/100cfg 3/1 will modify port 1 of the 24 on slot 3.

    Whats a CAM?

    Content Addressable Memory, which is used by the switch to extend the size and/or speed of tables like MAC and BGP. CAMs typically have processing power on them.

    Can I find the temperature?

    hdstat shows a line of temperatures for the last 1 min avg, and 1 hour avg and maximum.

    Still to document Channel Bonding VLANs SNMP
