• interface TeGig, xfp remains upward with low DBm Rx

  Hi, does anyone know why the interface remains upwards, when receives a lower than expected power. If we can avoid this? How?

  SPA-1X10GE-L-V2 with XFP-10GLR-OC192SR

  The sensitivity of the receiver (maximum) is SR-1 10GLR:-12.6 dBm

  We receive-20 but the interface remains upward.

  I think that its normal, repeatedly observed in the laboratory during re-ceates, photodiode stop detection beyond its penetrating recevier but light is sufficient to show the port and no problems with frames/traffic.

  but we can observe errors after a while.

  example:

  many NSO-XFPs penetrating release (tunable full) is of approximately - 26dBm, but they remain upward with low optical power close to-29,-30, sometimes 40 - illustrates power (doesn't mean no optical power) by the system.

  so its normal.

• Trouble connecting Netgear XS748T to Ubiquiti UniFi US-48-750W via Port SFP +.

  We bought a new switch Netgear XS748T and try connecting to our existing network which consists of several switches of Ubiquiti UniFi US-48-750W, and we try to connect using the SFP + 10 GB ports on the two switches. We have a Direct Link SFP + SFP + DAC, passive, 1 m, cable AWG30, we bought at Amazon / 10Gtek and when we try to use this cable between the Ubiquiti switch and the Netgear we get no link activity.

  However if we use the same cable between two of Ubiquiti switches it lights immediately and works very well, the same is true if we use the same SFP + cable between the switch Netgear XS748T and a XS728T that we must also. Its almost as if the switches detect the same manufacturer at the other end and right link up but when its manufacturer another pass on the other end, it does nothing.

  It is very aggravating, and Im going to be obliged to return the new Netgear switches. Can someone make a suggestion or confirm if they should or may not work? Everything simply connecting switches together using a cable of copper works very well but since our current switches don't support 1 GB via copper it provides not enough bandwidth for our use so we really need the port SFP + 10 GB to give us the uplink.

  Here is a link to the modules SFP + cable, we bought:

  https://www.Amazon.com/DP/B01LSGGUOY/ref=twister_B01M0ER4M0?_encoding=UTF8&PSC=1

  It seems that I solved the problem myself. I bought a set of:
  10Gtek for Cisco SFP - 10 G - LR, 10 Gb/s Transceiver SFP + module 1310nm 10km

  And the LR version worked instantly. I honestly don't know what's the difference between a SFP + SR module and a module LR SFP +, but for some reason any LR module has allowed these two switches to connect.

  Here are links to the modules and the cable used in case anyone needs a solution to this:

• PowerConnect 6224 piling on XFP

  Hi all

  Just curious about something I've been trying to find a hard yes/no answer on but have had no luck.  Long story short, I'm looking to pick up a pair of 6224 switches and would set up in a pile.  I'm looking at the use of fibers to connect and wonder if the switches will allow me to configure FJ727 XFP modules for stacking or if they will only help stacking if you use the CX4, UY108 or GM765 modules for stacking.

  My other question is that if I can use the XFP module for stack, it will force the XG1 and XG2 XFP module to use for the stack, or can I configure a port for stacking and the other for a 10 GB uplink to my router?

  Joekamel,

  Only CX4 modules can be used for stacking on the PowerConnect 62xx switch.  You can find more information about all the modules supported for the 62xx under 'N-Series Switches of Campus' at the following link.

  http://en.community.Dell.com/TechCenter/networking/p/guides

  If you download the file called 'Expansion Modules for network switches Dell' and go to page 17, it it shows all five supported modules and shows only CX4 to stacking.

• Should I more SFP + ports host if I add another tray of disk PS6210X

  Hi all

  We have a cluster of Hyper V of Server 2012 R2 4 nodes with each host with 2 10GbE SFP + dedicated to iSCSI traffic. We need to increase the capacity of the San and our supplier has quoted another shelf but said that we need another 2 10GbE SFP + ports in each of our guests. Is this correct?

  I was under the impression that all our guests are already "hooked" in the iSCSI with MPIO active tissue and must therefore not more physical iSCSI connections.

  If we opt to not install the additional iSCSI NIC will we lose performance?

  Thank you very much

  Gary

  Probably not. In a virt. environment, you have a random i/o with smaler blocksizes which means less bandwidth. If you have dedicated 2x10GbE you need a couple of members PS do deliver IOPS and fill this huge pipe.

  I suggest that you install SANHQ when its not already there and check the width of band and transferrates you already have.

  To compare I have 10 members of PS in 2 pools with 11 hosts (each of them have 2x10GbE just for iSCSI) and the sending of PS group around 400 MB/s and up to 1000 MB/s during the backup.

  I need an IOmeter and 100% with blocksie 256 KB sequential read workload to fill the pipes 2 x 10 a server.

  Kind regards

• Model SFP + cable for PC5524.

  I wonder what Dell cables for the connection between two PC 5524.  I intend to link between the distance of 2 racks about 10 m.

  Thank you

  Samuel S.

  I don't see any cable direct attach listed more than 7 m. Based on the price, the next option would be to buy SFP + SR transceivers.

  http://Dell.to/1iX326l

  This transceiver supports the OM1, OM2, OM3 and OM4 cables.

  400 meters on OM4 fiber

  300 meters on OM3 fiber (in other words, use aqua "OM3 LC/LC fiber cable")

  82 metres on fibre OM2 (orange fiber)

  33 metres on fibre OM1

  You can use one of these cables:

• 10 Gbps sfp + question of Dell X 1052

  Hey,.

  I am interested in buying a dell x 1052 switch but I have a few questions about its features.

  1. can I I aggregate the sfp ports + this switch? Basically, I want to lacp 2 sfp ports + 10 Gbit/s and then connect the ports on my server that has a double card nic intel 10 Gbps. I would use a Twinaxial cable so that the server and the switch have a link between the two 20gbps. so is this possible?

  2. can I connect port sfp + 10 Gbit/s directly to my computer that has a network of 10 Gbit/s Intel card?

  Thanks for the help

  After taking a glance at one of the switches in our lab, I can confirm that the SFP + 10 GB ports can be configured in a GAP between them. Here's an example of how ports appear in the running configuration once being configured to aggregate links.

  Running-config:

  !

  tengigabitethernet1/0/1 interface

  channel-group mode 1 on

  !

  interface tengigabitethernet1/0/2

  channel-group mode 1 on

  !

  interface tengigabitethernet1/0/3

  channel-group mode 2 on

  !

  interface tengigabitethernet1/0/4

• Connection EQL 6110 X (10G SFP +) PowerConnect 6224 10 Uplink ports

  Dear friends,

  Need your help...

  Please let me know if I can connect EQL 6110 X (10 G SFP +) storage to ports 10 G SFP + PC 6224 for iSCSI to my servers on a local network connectivity that is 1 G.

  Correct, do not use the uplink ports for Gigabit Ethernet switch for 10GbE tables.    It can connect, but performance and stability will most likely suffer.   So has been the experience of other customers who have tried to do.

• can I use both optical and fiber sfp modules?

  Hello

  I have 2 stacked 3548 P PowerConnect switches. The top switch got uplink fiber of 1 MM (G1) to another switch in a different building. If the top switch has 1 free uplink port and the lower 2 switch free uplink ports. Recently, we bought 2 servers Poweredge R620 and I would like to connect them to the Gigabit ports. The 'normal' switch ports allow only 100 Mbit/s, so I plan to buy 2 modules SFP 1000Base-T (for copper) to connect to them.

  Is this feasible? Can I use G2 on the top switch for SFP 1000Base-1 T? Is this allowed?

  Kind regards

  Erik

  Yes, it's quite feasible. The connection will be configurable the same 100 Mbps ports. Here is a link to the part number for the 1000Base-T transceiver.

• PowerConnect 6248 stacking using the front SFP Ports

  I am trying to stack two Dell Powerconnect 6248 switches. Currently they are chained together, but I modules fibre for the front sfp ports. Theoretically, I should be able to stack them. But when I try:

  stack 1/g45 #stack - port console (config-battery)

  Could not set the front panel stacking mode.

  Any ideas? Thank you!

  The PCT6200 requires a stack of modules installed in Bay 1 (XG1 XG2) at the rear of the switch. The stacking module uses CX4/Infiniband type stacking spacers.

  Stacking of front port / user is not supported

• PowerConnect 2824 Ports SFP does not

  We bought a new switch 2824 with a corresponding to SFP module replace old 2724 PowerConnect and SFP module.

  After the configuration of the switch and installing it, we were able to get a connection on our uplinked to fiber.
  SFP light illuminates and flashes from time to time, and the switch detects correctly module SFP is inserted and that the fiber is connected.  We can see the insertion of the SFP is detected and the switch for change of fiber mode by looking at the output of the console, and the web administration port status page lists the port as "ComboF" when the SFP is inserted and the fiber is connected.

  However, the switch always indicates that the port State is down.  (The port is not administratively disabled.)

  The old switch works very well with the old SFP module.  The new switch does not work with the old or the new module SFP.  We tried two combo SFP ports.  We also checked that the fiber itself is fine. We cannot get the new switch to display the drop-down list port status that up when you use the SFP. We tried to completely reset the new switch by removing the configuration file via the boot over the serial connection menu and re-run the initial configuration wizard, but the port still won't go up.

  Any ideas?

  After a few tests yesterday, we determined that part of auto-negotiation must be disabled for switch work with our copper and fiber Media converters.

  The 2724 works very well with our media converters, with auto-negotiation enabled.

  The 2824 works very well with auto-negotiation enabled when it is connected to an another SFP transceiver in building switch.

  But when we introduce the Media Converter in the path, the 2824 will bring only the link up if you disable auto-negotiation.

  So far, everything looks good.
