We are an Aruba shop for wireless as well and see very few APs in need of replacement (with the exception of the hospitality APs in our ResHalls).
I keep 2 of each model currently in production as dedicated spares in addition to those that have been purchased and not yet deployed for the same reasons mentioned by Bruce below. As for the hospitality APs, the ones we see needing occasional replacement are most likely a result of the conditions they’re deployed in. Common issues are mounting posts breaking off on the back, damaged pins on the Ethernet connections and not booting after who knows what has been done to it. I try to keep a few extra of these on-hand to replace as there are issues and RMA them with the lifetime warranty. - Michael Michael McGuire Network Systems Administrator Monmouth University mmcgu...@monmouth.edu<mailto:mmcgu...@monmouth.edu> 732.263.5589 [cid:image002.png@01D049D1.4BBE4E60]<http://www.monmouth.edu/> From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Osborne, Bruce W (Network Operations) Sent: Tuesday, February 27, 2018 7:46 To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Offline/Spare Gear Inventory Size We have needed to replace very few of our Aruba APs. We keep inventory mainly for the following reasons: 1. Temporary large event deployments 2. Coverage adjustments 3. Last minute projects that cannot wait for ordered equipment – We are a construction-heavy school. 4. Pull backs from areas being remodeled. Those moving in generally purchase newer equipment. 5. Lab testing for new configuration & troubleshooting. We try to keep some of our latest recommended model APs.

Do you keep a percentage of each model of AP in inventory, and what is your reasoning? Storms? Last minute/emergency wireless coverage needs? What percentage of your live gear do you keep as offline inventory? (100 live APs with 1 inventory AP = 1% offline inventory). With Xirrus, we had an offline inventory of more than 10% of live inventory. We kept that inventory to cover the high failure rate of the equipment, the incidence of hurricanes and lightning strikes in our area, the broad range of AP models on campus, and last minute large events in low coverage areas. We are evaluating the minimum offline inventory for our new Aruba gear as we finish up the vendor switch. I have been thinking 1-2%, but I want to see what you guys do first, and why.
