Hi! I completely understand this problem. If there are 48 end devices to be connected in a single switch and you are using SFP ports for Uplink. E.g. 2 SFP ports for uplink, then all you get is 46 RJ45 ports for end devices. In that case you have to procure 1 more switch for the sake of 2 end devices.
Unlike A2 series switches wherein all ports are active. No Combo port concept. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Wenceslao Poveda Sánchez Sent: Wednesday, January 12, 2011 5:32 PM To: Enterasys Customer Mailing List Subject: RE: [enterasys] B3&B5 issue Hi Shashank, this is the part. no. B5G124-48 Markus I understand what you tell, but I don't understand the reasons for that implementation. We have this type of switch B2H124-48 in my organization and it is 48+4 as you say, but this is not specified anywhere. In new ones (B3&B5 series) this behavior ("shared ports") seems a loose of functionality because at any case we'll have 4 idle ports. -----Mensaje original----- De: Devlekar, Shashank [mailto:[email protected]] Enviado el: miércoles, 12 de enero de 2011 12:34 Para: Enterasys Customer Mailing List Asunto: RE: [enterasys] B3&B5 issue Can you share the part no. of B3 & B5 switch e.g. B3G124-24 or B5G124-24 etc. Regards, Shashank -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Kaiser, Markus Sent: Wednesday, January 12, 2011 4:59 PM To: Enterasys Customer Mailing List Cc: Enterasys Customer Mailing List Subject: Re: [enterasys] B3&B5 issue Hi, the SFP ports of most B3/B5 and other SecureStack devices are "shared" ports and no additional ports (safest way is to look at the front panel port descriptions). You can use either the RJ45/copper port OR the SFP port. So if you use i.e. ports 21-24 of a 24 port switch with SFP, you can't use the same ports 21-24 in copper. But you can use port 21-22 with SFP and port 23-24 as copper port. If you, by mistake, connect all ports (port 21-24 SFP and port 21-24 with copper), then the copper ports will be prioritized and active, while the SFP ports stay down - as far as I remember. A 24 port switch has a maximum of 24 active ports, not 24+4, except with 10G switches (SFP+), there the 2 or 4 uplink ports are additional ports. Hope this helps. If there's a detail missing, please ask. Cheers, Markus Sent via iPhone.

In B3 and B5 switches we've adquired recently I have notice that SFP port aren't independent from GE ports. Can anyone tell how to work with SFP ports like additional ports and avoid overlapping with GE ones, like other enterasys series.
