No ping

When the SC0 is down

in the Enable mode:

switch#>config t

Swittch#>interface sc0

Switch# no shutdown

then it should come up

you could also try this:

show interfaces to see the status of the specific interface.

The PowerConnect switches have no SC0 interface for management. The management interface is specified by configuring an IP address on the VLAN, port, or LAG. The 3300 series switches can be configured with up to 4 IP addresses.

By default all interfaces on the PowerConnect switches are administratively enabled. If the port was administratively disabled, you can enable it using the "no shutdown" command from interface config mode. You can check the status of the port using the command "show interfaces status".

If the ports are administratively enabled, but the link is down, you most likely have a physical layer problem. Be sure both GBICs are the same wavelength (either SX/SX or LX/LX) and the fiber is correct for the type of GBICs used (MMF for SX, SMF for SX or LX). If possible eliminate any adapters or media converters between the two switches.

Negotiation mismatches also cause problems with fiber connectivity. Both sides of the fiber link must use the same negotiation settings (auto-negotiation or hard-set) or the link will not be established.

I called Dell Powerconnect tech support yesterday and after the technician ran me through several configuration steps he determined that the Gbic ports on the switch was bad, and is sending me a new switch today.

I must say I was very impressed with Dells tech support. The technician I talked to was very Knowledgeable

 and patient.

The new switch came in from Dell today. I'm still having the same problems as before.
Question: Shouldn't I be able to connect the 3324 switch in place of our old Cisco switch after I have assigned the IP address to the vlan and then put in our gateway address per Dells instructions and the switch should at least be able to ping the gateway with out further configuration? Dell support says it is probably a cabling issue.
We have a 3348 in our MDF approx 1000 feet away from the IDF with the 3324. The 3348 also has the same exact Gbic as the 3324 switch. Dell says these are the correct gbics. We have hard set the speed on both switches and also configured both for auto negotiation. Still no matter what we do we never get the status light for the Gbic port on the 3324 to come on. The speed of the old Cisco 1900's and the fiber transceivers we used was only 100, but the fiber is 62.5 multimode fiber and should be capable of 1000 correct?

Logically you should be able to use the same IP info, this sounds like a physical issue to me.

The distance limitation of MMF with 62.5 micron is roughly 720-900 ft, depending on the modal bandwidth (160/200 MHz/km). This is when using a SX wavelength. The specs for LX/LH wavelengths are 1800 ft for 62.5 MMF.

What was the wavelength of the old Cisco transceivers?

If you had SX to begin with, I would then try a loopback test. Put both SFP mini-GBICs into the same 33xx and use a simple LC-to-LC patch cable to connect them. Spanning tree will block one port, but the ports themselves should come up. If this works on both switches, you have narrowed the problem to the cable run.

Hi, there

assuming you are using the 3324 GBIC modules with the Glas fibre are the fibre cables crossed ?.

does the PC/ client ping inbetween them ok ?.
