I can tell you that we have had good experiences with Linksys overall, but
absolutely HORRIBLE experiences with the SRW248G4P. The switch has QoS
capabilities and we found that if we tried to turn any of it on the switch
became very unstable. We found the only way the switch was usable was at
factory default settings without taking advantage of any of its features.
At this point, it was a dumb PoE switch only.

Subject: RE: [on-asterisk] Hardware specs for 40 seats
Thanks for the input guys. Could this setup work without a hiccup:
- High end server with lots of RAM and CPU power + 5 Sata 750GB HDDs. Trying
RAID 5 with this. Client needs to record every single call. 8 hours shift *
20 sets.
- Sangoma 2XT1 card with echo cancel = 2 PRI
- Linksys SRW248G4P (48 port poe; 15.5W for 24 port POE or 7.7W if all 48
ports used)
- 48 Sets of Aastra 51i (apparently they are POE ready and don't need an
AC Adapter)
- 24 gauge unshielded of 25 pair cable
1- Not sure how many of the 25 pair should run. Would POE be fine over this
type of cable? (interference of unshielded cable with POE). How 48 Aastra
51i power up using the forementioned Linksys switch?
2- Computers connect to the phone. Internet usage is not really high.
3- No cables bought so far. I am flexible with dropping as many cables as I
want. What type of cable should be used?
