Maintain service coverage for eligible Cisco Catalyst 3850 switches with Cisco Smart Net Total Care at the 8x5xNBD service level. CON-3SNT-WSC385X2 supplies a three-year term, combining access to Cisco technical support during standard business hours with next-business-day hardware replacement service. It applies to the covered Catalyst 3850 equipment rather than adding switch ports, power, or network functionality. The 8x5xNBD designation suits networks supported during normal operating hours, including campus access layers, office distribution closets, and branch switching environments. Technical assistance is available eight hours per business day, five business days per week. When a covered hardware fault requires replacement, the service level provides next-business-day replacement rather than a same-day or 24-hour commitment. This contract differs within the Smart Net Total Care service range through its specific combination of a three-year coverage period and 8x5 next-business-day response level. Select it where the installed Catalyst 3850 hardware requires continued Cisco maintenance coverage but the site can accommodate next-business-day replacement timing. The contract must be associated with eligible covered equipment and active service entitlement.
