4800G IRF Stacking

[slittle]

The 3Com 4800G family configuration giude states only 4 switches should be IRF stacked. We have a network upgrade that requires 7,5,3 and 2 switches in each stack and were condiering the 4800G. Can someone confirm if it is still limited to 4 switches in each stack?

"You are reccommend to connect at most four switch 4800G series switches to form an IRF"

The 4800G switches can support up to nine switches in a stack, using XRN feature in the later version. Take a look on the datasheet specifications (Page 6):

----------------------------STACKING-----------------------------------


Use optional CX4 or XFP connections for high-bandwidth stacking of


multiple units


Resilient stacking; full duplex bandwidth of 96 Gbps when using CX4


cables and link aggregation (48 Gbps without aggregation); 40 Gbps when


using 10-Gigabit connections


Single iP address and management interfaces for stack-wide control


hot-swappable, closed-loop resilient stacking


Distributed Resilient Routing with router tables in all units; no


master/slave arrangement


Combine any Switch 4800G models into a single stack, up to 9-high, when


using XRn technology
