We are a smaller campus, and have experienced a very low failure rate, but still try to keep at least one spare of each type of AP that is currently installed on campus.
Bruce Entwistle Network Manager University of Redlands From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Trinklein, Jason R Sent: Monday, February 26, 2018 10:21 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: [WIRELESS-LAN] Offline/Spare Gear Inventory Size Hi All, I’m curious to know the size of your spare gear inventories. 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.
