D-Link DGS-3630-28SC 28-Port Gigabit Layer 3+ Managed Stackable Switch (24 SFP / 4 Combo 1000Base-T, 4 x 10GbE SFP+)

You've got a fibre backbone that needs more ports, and the last switch you tried couldn't stack or handle L3 routing without a separate appliance. This fixes both. The DGS-3630-28SC gives you 24 SFP slots (4 of which are combo 1000Base-T) plus 4 dedicated 10GbE SFP+ uplinks, all in a single xStack-managed chassis. Layer 3+ routing is built in — though full advanced L3 features need the Enhanced Image Licence, so factor that into your budget before you hit go. Stack multiple units and manage them as one logical switch. No separate controller, no extra rack space for a management appliance. If your site's growing past what a single 24-port box can chew through, this is the step up without ripping out your cabling
