Competitor Comparison & Analysis - Art of War Myth: Why DGS-1210 switches need the additional 4 ports? Truth: Cisco SG200 series offer extra 2 combo ports. Netgear GS748T and HP v1810-48 offers maximum 4 fiber ports. Counterplot: DGS-1210-20/28/52/28P give 4 more Gigabit ports at the same price. It is trend to offer more switching capability for the rising demands of connecting to the Internet through a variety of devices. Competitor’s new models also offer additional uplink ports. 33

Competitor Comparison & Analysis - Art of War Myth: D-Link does not have 48-port Gigabit PoE Smart Switch. Cisco has SG200-26P and SG200-50P PoE switch with competitive prices. Truth: Cisco SG200-26P offers only 12 PoE ports with 100Watts power budget, and SG200-50P offers 24 PoE ports with 180 watts power budget. Counterplot: DGS-1210-28P provides 24 PoE ports with 185 watts power budget, which offers more flexibility for powered device installation. For SMB customers who have budget limitation, a 24-ports Gigabit PoE model is sufficient in terms of functionality and price. 34

Competitor Comparison & Analysis - Art of War Myth: DGS-1210 switches are not competitive when comparing to Cisco SG300 series and Netgear GS700TS series? Truth: With Static Route and Virtual Stacking, DGS-1500 switches are the right match to compete against SG300 and GS700TS switches. Counterplot: DGS-1500 series support Static Route and can virtually cluster 32 units and be managed through one IP address. 35
