Dears, I have this old foundry switch in the warehouse, I have no experience in Foundry, i wonder if this switch can be upgraded to a newer OS that will support advanced features or shall i consider it dead, I want to mainly use it for one customer that wants caching, its L4 i guess and i have an old NetApp caching server that will save the customer 10MBs i guess. telnet@foundry-switch#sh ver SW: Version 07.3.04T12 Copyright (c) 1996-1999 Foundry Networks, Inc.
