5 out of 5 eggsGreat for advanced home networking!

Pros: This switch is excellent for both small business and home networks with specific configurations. Here is why:

-VLAN support.

-Excellent, clean build. Great ventilation. Stays cool.

-Very low power consumption.

-Fanless = dead silent.

-Standard NEMA 5-15P to C13 power cable that plugs directly into the back of the unit. (No external power supply. Helps rack hygiene.)

-2 extra gigE ports (ge17 and ge18). Great for segregating specific, prioritized devices. (Just a personal preference.)

-Nice HTTP GUI. The abundant options are apparent in a tree-like view.
(SAMPLE SG200 GUI AT CISCO'S SITE: goo.gl/odyL5)

-Fast-pulsing LED's consistently show traffic.

-Fast, consistent throughput.

CONNECTING THROUGH CABLE MODEM (CPE) DEVICES? YES! YOU =CAN= CONNECT THE LAN PORT OF A CABLE MODEM TO THE SWITCH WITHOUT THE CABLE MODEM "LEARNING" THE MAC ADDRESS OF THE SWITCH =WITHOUT= DISABLING SPANNING TREE PROTOCOL! (See my notes in the "Other

Cons: Firmware revision: 1.1.2.0

This switch has a few, minor nuances... But ultimately it is configurable enough to conquer all operational issues. Paying attention helps.

-NOT SAVING SETTINGS? Understand the difference between "Running Configuration" and "Startup Configuration". "Running Configuration" operates in volatile memory and will be lost on reboot if you don't save to "Startup Configuration". "Startup Configuration" is saved to flash and will load when the switch boots.

-GUI is organized but very slow when committing settings. (Minor annoyance.)

-Boot time: 1.5 - 2 minutes.

-Cisco Discovery Protocol (CDP) broadcasts switch's MAC to CPE devices. (Such as cable modems.) This causes the MAC of the switch to be "learned" by the CPE device which may block other intended devices from getting their IP from the CPE device. DISABLE CDP IF USING A CABLE MODEM.

-NTP settings are unclear. Must set DNS in switch for NTP to operate. But...NTP doesn't seem to work at all.

Other Thoughts: USING THIS SWITCH WITH A CABLE MODEM?

FOLLOW THESE INSTRUCTIONS TO PREVENT CPE MAC LEARNING! (APPLIES TO ALL SG200-xx SWITCHES!)

NOTE: DISABLE ALL POP-UP BLOCKERS FOR SWITCH'S IP!

1.) Enable the CDP service.

2.) Switch to: Discovery - CDP > Interface Settings.

3.) Find the port that your cable modem's ethernet port is connected to on the list.

4.) Select the cable modem's port using the corresponding radio button then click the "Edit" button at the bottom. A pop-up window** should appear.

5.) The port number that you selected should show in the "Interface" drop-down box. Make sure that it does show the "GExx" port of your cable modem.

6.) Uncheck the "Enable" box for all of the following options then click "Apply" to save the config:
-CDP Status
-Syslog Voice VLAN Mismatch
-Syslog Native VLAN Mismatch
-Syslog Duplex Mismatch

7.) You'll need to reboot the cable modem to clear the SG200's MAC from the cable modem's list of recorded MAC address.

5 out of 5 eggsAwesome switch!

Pros: Great switch. No noise. Great quality. Great set of features. Nice looking GUI. IPV6 ready. Overall much better than other switches of similar class I purchased over the years.

Cons: The web GUI is really nice except for a pop-up window here and there. It's kind of annoying. Wouldn't you be able to make it out of JavaScript and work in the browser window?

Other Thoughts: So far I couldn't be happier. Finally all the standards supported are honored unlike others.

Also, when making configuration changes remember to safe the settings because when you reboot they'll all be lost.

Reviewer who lost the settings should read the manual.

5 out of 5 eggsyou want this switch

Pros: Very low wattage/low heat. This is the home switch you are looking for. It does NOT have a screaming fan, its easy to configure, supports an extensive set of networking features.

Cons: I clicked on "reboot" to reboot the unit and it did a reset to factory defaults. I would say that is a major bug. Now I pull the power cord if I want to reboot. Also, I really want 10 gigabit SFP+ ports but I guess I will have to wait another 10 years for that.

Other Thoughts: Other manufacturers cant seem to make a low wattage gigabit switch. I have done extensive research and this looks like the lowest wattage usable switch out there. Another mfg has a lower wattage "green" switch but it doesn't even have a web management interface!

4 out of 5 eggsOverall...

Pros: *Has 16 Gig ports, ability to setup VLAN's, and other features normally found on enterprises switches for a moderate price.
*Nice to have the miniGbic ports for expansion or stacking of switches.
*Very quiet and came with hardware to mount in my rack.
*Supports many 802.3 protocols.

Cons: *The web interface is clunky for someone who is used to Cisco IOS CLI.
*Some of the terminology used in the web GUI is misleading when compared to IOS commands which led me down many rabbit trails during configuration.
*The web interface can lock up at 50% while loading and hang, even with latest firmware.
*Additionally, did not see the performance you would expect from a GiG switch when fully loaded and connected to an enterprise class router. May be due to the fact that I had 5 ports fail within a few days of setup, will see when I get the replacement.

Other Thoughts: *Not really a con, but only layer 2
*Had to RMA after only a few days, 5 of the ports failed
*Specifically got this switch as a replacement for a Cisco 2950 that failed, wanted to use for LACP/802.3ad on an iSCSI box used in my home lab. Testing went well till ports started failing.
*Overall, good switch when it worked, took a little more effort to configure due to the web GUI freezing and the differences in terminology. Would only recommend to someone who has a good understanding of general network protocols.

Manufacturer Response:
