Netgear Switches

[leco]

I have just installed:

1 x Netgear GSM7248-200-EUS and

2 x Netgear GS724TP

I have connected each 24 port switch to the 48 port via patch leads.

 

48 port switch is fine, I've given it a static IP, and it's talking to/taking packets from all the devices I have plugged in. However, the 24 port switches are a different matter. I've also given them static IPs but unless I plug my computer into that switch I cannot communicate with it i.e. no web interface. The same goes for the other 24 port.

 

When I run an IP scan the switches are not listed. If I'm plugged into a switch there are only two IPs. My computer and the switch.

 

What have I missed or doing wrong?

are you trying to connect to it from a hp server by any chance?

[leco]

Not HP but from my custom workstation. I've also tried one of the latops (IBM) with the same result, only the latop and the switch are shown and no network.

[sted]

id be tempted to try upgrading the netgears firmware as the ones weve used recently have needed it to talk to hp servers may be a similar issue (im not sure on model numbers as its not an issue ive personally had)

[leco]

These are brand spanking new switches, should they need a firmware upgrade so soon?

unfortunately yes

[leco]

unfortunately yes

Well I should have known, since everything else needs an upgrade as soon as it's installed More homework required methinks.

You can download something from the Netgear site called 'Smartwizard Discovery' which will scan for switches and check that the IP addresses are valid. If you have power cuts you'll need this to identify which switches have reset and come back without a valid IP address.

[leco]

Thanks I have that already on my workstation - it doesn't find either switch unless my machine is plugged in to the switch. Then it finds the switch that I am plugged in to.

try enabling SNMP on the switches as a bit of daft, that may just work.

Why might that work? Maybe because they'd be talking to the other switch on a different channel perhaps? I'll give it a try tomorrow anyway, thanks.

[RobMongoose]

Have you checked to see if there are any settings that would specify which ports are used as trunking? I have seen switches that did similarly irritating things for this reason before.

[leco]

Trunking meaning that some ports may or can be set for switch to switch?

[john]

trunking meaning joining more than one port together to boost performance.

 

If they are dual personality ports IE some shared with the fibre SFP ones avoid using them as despite the fibre SFPs being empty I have known the copper ports be a bit weird at times!

[leco]

Ah tight, thanks. There are some fibre ports but I'm not using them.

[john]

On those switches avoid the last 2 ports then as they are dual personality ones, so put your uplinks into ports 21 and 22 etc leaving 23 and 24 empty as they are shared with the fibre ports that your not using to see if that helps. You also don't need cross over cables just straight ones.

[leco]

The cables are in port 22 on the smart switches to 41 and 43 on the managed. All of the switches purport to "know" what kind of cable is plugged in. However, as that may not be the case, how do I tell if I've got straight or cross-over patch leads?

Look at the wires on the plug. If they are the same sequence at both ends, then they are straight, if they have some wires switched around then it is a cross over.

[leco]

Thanks, logical when I come to think of it.

[Hecate]

if you set them to use DHCP do they get an IP address?

[leco]

No, even with DHCP set as they are uable (or unwilling) to connect to the DHCP server. The switches only see what is directly plugged in to them - well that's apart from the other switches of course.

[Dos_Box]

Do they have a static IP adress as a default factory setting? If so you may just have to connect via a laptop and fettle them manually to start with. I seem to remember having to do this to to some Netgear switches I had a while back.

[leco]

Thanks DB I've already done that, erm several times with no luck. Leaving it for now as I have more pressing things to do like rebuilding the master DC.

HAve you upgraded the firmware on the switches yet? Should be 5.0.0.23 on the GS724T. I recently had the exact same problem connecting these to a GSM7352 stack, hte firmware upgrade was the most likely cuase of them to start working again.

I haven't as yet. Do you by any chance have a URL to find the firmware please? I tend to get lost in the site whenever I go in there.
