#3: Daisy chaining
As organizations grow, particularly small businesses, outside IT contractors often implement simple solutions. Many consultants choose to simply add a five-port router to an existing four-port router/firewall. Small businesses everywhere boast just such a setup.
However, as switches are added to a network, data packets must navigate additional hops to reach their destination. Each hop complicates network routing. Depending upon the amount of traffic a network must support--and even a small dentist's or doctor's office can easily stress 10/100 Mbps systems due to X-ray imagery, patient file information, and other data--the addition of an extra hop or two can spell the difference between a smooth running network and one that frequently slows employee productivity to unacceptable levels.
Resist the urge to daisy chain multiple network switches and routers. Instead, plan for capacity. Or if unforeseen growth has resulted in successive connected switches, eliminate as many devices as possible through consolidation to a more potent and scalable unit.
