This review is from: Tripp Lite AV550SC 550VA Tower UPS
Pros: All metal rugged contruction
Two year factory warranty
Silent, no beeps/alarms only indicator LEDs
Fits nicely inside the 42" On-Q Legrand structured wiring enclosure
Has a 60s delay-on feature for the router plug to give time for the modem to power up first
Has a 12VDC output you can use for some enclosure accessories (but not security alarm boards which need 16VAC)
Cons: No remote monitoring/remote self-test capability
Only 8-10minutes of reserve power (battery backup running time)
Battery is an uncommon and difficult to locate type in retail stores (available online though)
Other Thoughts: Tripp Lite claims the battery is not user serviceable, but you can replace it yourself if you are a DIY type.
Measures approx 8.5in H x 7in W x 3in D
Off white/light tan type paint color
This review is from: D-Link 16-Port EasySmart Gigabit Ethernet Switch (DGS-1100-16)
Pros: - I received the latest level of this switch hardware wise when ordering version B2. The firmware installed was the latest, 1.01.018 at the time of this review.
- For the price point, this switch includes a number of features and support for many standards. Including SNMP, LLDP, RSTP, and SNTP. The firmware also includes several QoS and security features, with granular control in most cases.
- The switch has a built-in, rather than separate brick, for the power supply. And it comes with a retainer for it along with metal rack mount ears and fasteners.
Cons: - The firmware has a very unfinished feel to it. Here are just a few glaring examples:
1) No display of the currently negotiated link rate on the port
2) No fields to set RSTP parameters (the priority & election defaults are hard coded in the firmware)
3) No timezone setting, you have to manually enter the UTC offset!
4) Cryptic DayLight Savings Time fields (the fields are there but labeled as "Date Setting"
5) LLDP neighbors are shown, but the DGS-1100-16 does not broadcast it's own details just the MAC address :(
6) If you choose to be more secure and enable HTTPS, the firmware does not redirect the browser
7) The system name (hostname) does not show up for linux DHCP servers
- Online help documentation is rather poor, often simply repeating what you see on the webGUI so offering no additional value in explaining what the feature or field is for or the options you have available in configuring it.
Other Thoughts: Overall this would be a 5 egg switch if the firmware & documentation got cleaned up. You can work around the current rawness, and its a reliable piece of hardware regardless.
I also wanted to point out initially we had an incompatibility with our Vonage VoIP box, and this turned out to be corrected by disabling the Blat Attack algorithm in the DoS Attack Prevention Settings. Great that D-Link had the granularity to cherry pick the problematic algorithm without having to disable the whole feature, but much time could have been saved with some documentation pointers to possible incompatibilities with SIP.
This review is from: HP PS1810-8G Fixed 8 Port Web Managed Gigabit Ethernet Switch
Pros: This switch is designed to be used with the HP Gen8 Microserver, and has a form factor to sit on top or below the server. You will need three Ethernet ports when using them together, two LACP trunked for the NIC team and another for the iLO port.
The switch works great standalone too, though the form factor is going to be odd if you go that route. It does include rubber feet for desktop mounting.
I first updated the firmware to PS.2.07 which came out in Feb 2016. So this switch continues to receive firmware luv.
I found the firmware webGUI very nicely done with only a few comments down below in the other review sections.
You have good support for a number of standards including RSTP, SNTP, SNMP, LLDP, and LACP. Security wise you can setup the webGUI to be accessible by HTTPS only and the firmware is smart enough to redirect your browser (unlike many other brands in this price point).
Great that the ports are on the rear, so many desktop switches are going the other way which can be undesireable for an out of rack application within a non-IT office environment.
Cons: - HP includes a white nylon tie to secure the power connector on the rear with a loop built into the metal case housing. Unfortunately they do not explain in the PS1810-8G manual what this is for. You had to have used HP switches in the past to know. Plus the metal loop is right above the connector instead of to the side making the feature less useable.
- The HP firmware website is frequently down, this is something that started with HPs split company wise. There are some forum posts about the problem and workarounds, you do need to put on the latest firmware to get all the bug fixes.
- The firmware features for DoS Attack and Storm control give you no customization. It's all or nothing on DoS, and no control over the storm rate. For DoS this is a problem as some printers and VoIP devices have conflicts with the Blat Attack algorithm. You should be able to turn this off without losing all the others.
- That an 8-port switch quickly becomes a 4-port switch when used with an HP Gen8 microserver (uplink port, iLO port, plus an LACP link agg for the two NICs).
Other Thoughts: - I found the firmware feature for 802.3az for Low Traffic Idle (EEE) caused the uplink port to be disabled when connected to a D-Link switch. Most likely a D-Link firmware issue but just pointing it out that if you sudden lose access when setting the Green Features it could be this.
- Also I found that at 7AM and 7PM this switch sends out some sort of UDP broadcast which shows up as an error in the router log: miniupnpd: Unknown UDP Packet Received Port:1024. The error is linked to the IP address of the switch itself. It generates this log entry two times at each time index daily. When this broadcase happens, ironically, the only device negatively affected is an HP C7280 printer. All its lights start flashing due to a firmware error and it has to be reset lol.
