Questions & Answers



Q:
It would be very nice if this model had the POE+ option. By Alonzo.Smith on 09/04/2019

A:
Thanks for your question. The S3900-24F4S doesn't support the PoE+. The PoE+ Switches in our website can better meet your needs. By FS on 09/06/2019
Q:
Does this switch support a copper 1G optic such as the GLC-T? By Timothy.Vorschirm on 08/09/2019

A:
Thanks for your question. Yes, S3900-24F4S switch supports a copper 1G optic such as the GLC-T. We recommend #11773. By FS on 08/10/2019
Q:
Is their sample configuration for this switch? By Tom on 06/12/2019

A:
Thanks for your question. The sample configuration is for S3900 Series switches, including the S3900-24F4S switch. Please refer to S3900 Series CLI Reference Guide. By FS on 06/13/2019
Q:
Can this switch provide DHCP addresses for devices? By jdmickies on 05/20/2019

A:
Thanks for your question. The S3900-24F4S can't provide DHCP address for devices, and it doesn't support DHCP server but only supports DHCP relay, while our S-Series switches support DHCP server and DHCP relay. By FS on 05/21/2019
Q:
We are looking for a stackable access switch, and the switches will need to carry tagged/untagged VLAN traffic. Does this switch support it? By Sergejus on 03/23/2019

A:
Hello, the S3900-24F4S can satisfy your need. The S3900-24F4S switch can tag or untag the traffic by configuring the VLAN. By FS on 03/23/2019
Q:
Does this model of Switch support Radius and other access control protocols? By Network Wombat on 03/14/2019

A:
Yes, the S3900-24F4S supports Radius, Tacasc+, 802.1x, etc. More detailed security features, please kindly check the product datasheet. By FS on 03/15/2019
Q:
Does S3900-24F4S Port Gigabit Stackable SFP Managed Switch with 4 Combo SFP and 4 10Gb SFP+ Uplinks supported Optical Transceivers and Cables below ? • 1G SFP, 1G BIDI SFP, 1G CWDM SFP, 1G DWDM SFP, 1GBASE-T • 10G SFP+, 10G BIDI SFP+, 10G CWDM SFP+, 10G DWDM SFP+ By AUGUSTE on 01/21/2019

A:
Hello, thanks for contacting FS.COM. Yes, confirmed that the S3900-24F4S's 4 x 10G Uplinks ports can support 10G SFP+, 10G BIDI SFP+, 10G CWDM SFP+, 10G DWDM SFP+ modules, and the S3900-24F4S has another 4 x Combo SFP ports which can support 1G SFP, 1G BIDI SFP, 1G CWDM SFP, 1G DWDM SFP, 1GBASE-T modules or RJ45 cables. About the 4 x Combo ports: The Combo interface is also called an optical multiplex interface. It consists of two Ethernet ports (one optical port and one electrical port). The Combo electrical port and its corresponding optical port are logically optically multiplexed. You can select one of them according to the actual networking situation, but the two cannot work at the same time. Hope above explanation will be helpful to you, any further assistance, you can feel free to email your Account Manager, thank you. By FS on 01/23/2019
Q:
Is this sfp or sfp+? By pennakira on 01/14/2019

A:
Thanks for your question. #72945 has sfp ports and sfp+ ports. Thanks. By FS on 01/15/2019
Q:
I get Fan fails on 3 switches I have tried, is that a software problem or hardware problem? The fans work but they go on and off all the time.. By lonnestig on 12/12/2018

A:
Thank you for your question. I guess the problem in switch version, please kindly check and keep the version on 1.62 to resolve this problem. If it still doesn't work well, please let me know. By FS on 12/13/2018
Q:
20-Port support : 100-FX ? only 1Gb SFP ? In general, L2 management switches are both supported. Have you tested the SFP port speed after setting 100 Mbps? I would like to inform you after the actual test. By jaesik on 12/11/2018

A:
I am sorry to the 20-ports is only 1Gb SFP supported currently, but this function will available soon, your sales will keep you informed. By FS on 12/12/2018
