New switches - 3500's
« on: February 10, 2012, 04:00:02 AM »
Just got a little bird singing about new 3500 series, aimed at replacing/complementing the 2500 series...

This series seems to be filling the gap between the 2500 and 4500 (pricewise and featurewise)

Main differences:

10 port gigabit versions (fanless for non-PoE or PoE with a power budget up to 60W)
24 port PoE versions (10/100 and 10/100/1000)
24 port 10/100 (fanless)

All PoE+ capable.

Release to market seems to be pointed for end May 2012...

Interesting,

although I think the model number could have been choosen better: Nortel already had a 3510 model in the past which they ditched fairly quickly..

Do you perhaps have any specs on the new models?
Kind regards,

I am getting information now on the ERS3500 family of switches.  Interesting stuff.  They are positioned for "Entry level enterprise, small branches and SME".  They even have fanless models for places where they don't want a loud switch running in the open.  Like classrooms, meeting rooms, under desks and home offices.  No license required for stacking and they say they support hot-swapping of units in a stack.  However stacking cables do not come with the switches ( that support them ) and are ordered separately.  Also seem to integrate with the Avaya 8100 wireless AP's in some way.  Still finding out more about them.  They should be available by the end of April from distributors.  They look like they will add some 48-port units down the line to the 3500 family.

ERS 3510GT
 - 8 x 10/100/1000Mbps + 2 SFP ports (Standalone & fanless)

ERS 3510GT-PWR+
 - 8 x 10/100/1000 Mbps PoE+ ports + 2 SFP ports (Standalone, dual power - fanless 60W / fan 170W modes)

ERS 3524GT
 - 24 x 10/100/1000Mbps with 4 shared SFP ports + 2 SFP / 2.5G rear ports

ERS 3524GT-PWR+
 - 24 x 10/100/1000Mbps PoE+ ports with 4 shared SFP ports + 2 SFP / 2.5G rear ports (PoE budget 370W)

ERS 3526T
 - 24 x 10/100Mbps + 2 Combo 10/100/1000 or SFP ports + 2 SFP / 2.5G rear ports (fanless)

ERS 3526T-PWR+
 - 24 x 10/100Mbps PoE+ ports + 2 Combo 10/100/1000 or SFP ports + 2 SFP / 2.5G rear ports (PoE budget 370W)

Major Features
- Layer 3: Local and Static Routing, DHCP relay, Proxy ARP, UDP fwdg,
- Security: 802.1X, IP Src Guard, DHCP Snooping, ARP Inspect.
- Convergence: Advanced QoS, Avaya Auto-QoS, 802.3af & 802.3at PoE+, ADAC, 802.1AB LLDP, MED, Location TLV.
- Resilient stacking*
- MLT/LACP (6grps x4 links), VLACP

Hardware Scalability
- 16000 FDB entries
- 256 VLANs (port based)
- Nortel STP 1 group
- 802.1s MSTP 8 groups
- 802.1X 32 EAP clients per port

Looks like stacking speed is limited to 10Gbps per switch.  Not bad for what they are designed to do in a small wiring closet, but not usable in the data center.

Stacking will be supported in a future software release..

The fanless 8 port models will be interesting as an alternative to the cheap**s boxed now placed under the desk because of insufficient outlets, but with support for vlans etc..

If you Google "Avaya 3524gt" you can find a preliminary data sheet on the new 3500 series..

Think I might try to order one or two of the fanless units so I can throw them in meeting rooms where they want to do training with a dozen laptops, but there are only 2 data ports.  It looks like the initial software release won't support stacking, but I can't think that code release that will enable stacking is going to be too far behind.
