Rolling Review: 3Com Baseline Switch 2900 Plus: Page 2 of 3

We were likewise happy to find that the PoE capability worked as expected. Other PoE switches require purchase of an additional power supply device because they don't provide enough wattage out of the box to power devices on every port. This was not the case for the "PWR Plus" model, which provides up to 180W total power across its 24 ports; each port can provide 7.5W if the power is evenly distributed. The Cisco IP phones we used require only 6.3W per device. Additionally, each port can be allotted a specific amount of power through the Web management interface, so you can reserve power port by port. The switch also has LED indicators on the front panel that indicate which ports are using PoE.

Helpful Help Files

Setup was painless. The management interface will either acquire a DHCP address from the network or fall back to a predefined static address if it doesn't find a DHCP server. The switch comes with a single VLAN configuration, meaning it operates as an unmanaged switch until directed otherwise. This is convenient for those with the most basic of needs, but you'll want to reconfigure it to take advantage of features such as the auto-voice VLAN.
We were pleased that the Web interface supports the Safari browser; we've had trouble in the past with Dell switches requiring Internet Explorer. The Web interface is clean, logically organized and easy to use. Though we generally don't get excited about documentation, clear and concise help files were provided on each management interface Web page. When we encountered unfamiliar features, the help files actually cleared up our confusion. That hasn't been the case with competing switches, whose documentation often seems to have been translated from another language.

Included in the packaging are the power cord, console cable, mounting hardware, and a CD with documentation. 3Com chose to use an RJ-45 (Ethernet) connector for the console port on the front of the device, so the console cable is an RJ-45-to-serial adapter. This is very useful for management on a larger scale, in the sense that CAT5 cabling can be used to connect to the switch's console ports instead of having to run serial cables through an existing setup.

We were impressed with 3Com's switch, and excited to see emerging voice technologies built into the product. Combined with PoE and Gigabit speeds, this switch should be considered during your next network deployment or expansion.
