RPS 2300 together with 3750 - 48 PoE and Cisco 2821

Hi,
I'm wondering what kind of power modules to include in RPS 2300 (750 or 1150 Watt) to provide redundant power supply for 1 x Cisco 2821 router (standart power supply) and Catalyst 3750 with PoE 48 ports.
Thanks

I am not qualified to answer your question... I would like to mention to be careful when calculating power for phones, because some of the phones (especially color) will take more power than others. We ended up only being able to support 24-ish phones on a 3750 due to power limitations.

  • Original and current budget together with PTD,ITD,MTD and YTD labor...

    Hi experts:
    I need a Project Accounting Report that shows Original and Current budget together with PTD,ITD,MTD and YTD labor amount, labor cost, non-labor cost, and revenue on the same line for all the task_id for a project. I know these are coming from these ,PA_BUDGET_VERSIONS V, PA_RESOURCE_ASSIGNMENTS A,PA_BUDGET_LINES L, main tables. But I am unable to break down the amounts according to PA and GL periods. Can anyone help please?
    Thanks a million , in advance.

    Help you with what?
    No database version number.
    No application name or version number.
    No DDL.
    Do you, for some reason, think we have any idea what PTD and ITD are? If so why?
    Do you think we all have your version of a table named PA_RESOURCE_ASSIGNMENTS on our hard disks?
    Perhaps you have some version of e-Business Suite. Perhaps you have SAP. Perhaps you have something we've never even heard of.

  • Mavericks VPN dropouts with native VPN client and Cisco IPSec

    Since update to Maverics I am experiencing VPN dropouts with native VPN client and Cisco IPSec
    I am connecting via a WIFI router to a remote VPN server
    The conenction is good for a while but eventually it drops out.
    I had Zero issues in mountain lion and only have issues since the update to 10.9
    I had similar issues in teh past with an unrelaibel wifi router but i am using a Verizon Fios router and it has worked impecably until mavericks
    My thoughts are:
    1 -issue with mavericks  ( maybe the app sleep funciton affecting eithe VPN or WIFI daemons)
    2- Issue with  cisco router compaitibility or timing with Cisco IPSEC
    3- Issue with WIFI itself on mavericks - some sort of WIFI software bug
    Any thousuggestions?

  • LAN2LAN between ASA and Cisco 2821

    Greetings,
    Users on remote network behind Cisco 2821 reporting dropped connections to mail server behind ASA. 20-seconds later, the connections get re-established. I run a constant "ping" to the remote LAN and do not see a drop over the tunnel.
    Any ideas?
    Thanks.

    Thanks for the quick reply.
    As I understand what I've read - esmtp inspect is on by default on the ASA. Is that true? So - in this case - would I turn it on in the router as well? BTW: These two sites are on a LAN2LAN VPN .... does that change what you suggested?
    Thanks.

  • Since updating my Ipad it has crashed showing the I tunes logo and charge cable I have tried holding down the top button together with the round button and it still goes back to the I tunes logo

    how do i get my i pad back after it has crashed

    I had asked this same question on Friday at work but had to wait until I got home to plug into my computer at home.  I was able to at least get back on my ipad but it managed to download so much, such as all my apps, even the ones i had gotten.  I had run the recovery mode several times as suggested, but now i have lost all my progress on games as well as my NY times subscription.  I am going to try to reinstall my NY times app, but the games are from games center--does anyone know how to get my progress back on those games?  Thanks so much!

  • Issue with hp ipaq 614c and cisco ap

    Hello. I tried to connect an ipaq 614c to a cisco ap1131 using wpa-psk tkip with no success. The ipaq connects without any problem to other access points including linksys. I've tried odysey client and I get the message: waiting for keys. The event log of the AP says: Packet to client reached max retries, removing the client. I am able to connect with other models of ipaq to the ap. Anyone know what the problem might be? I also tried disabling QOS but the result is the same.

    Is the ssid only config for 1 security policy? I had an issue one time where the SSID was config for both WPA and WPA2 and i had issues. It wasnt till i selected just a single security policy that it worked.
    You may want to try a real simple key at first. Try connecting it to an open network. Start 'unpacking' it so to speak...
    You may see more info if you go into the CLI of the controller and debug the client. Also, if you have a layer 2 analyzer (AirMagnet or Peek you may see something of interest...)

  • Problems with iOS 7 Mail and Cisco Unified Messaging attachments?

    Does anyone out there use Cisco Unified Messaging in their workplace? I am seeing an issue with iOS 7 (7.0.0-7.0.2) where the following scenario occurs:
    You check an email in the Mail app that is from the Cisco Unified Messaging system when you get a voicemail. The voicemail is left by Person A who attaches a subsequent voicemail from Person B and they leave an intro saying "Attached is a voicemail blah blah blah"  The email from Cisco comes across as having a .wav attachment and then an email attachment with a .wav file inside (supposed to be the original voicemail from Person B). If you play both .wav attachments, it just plays the same audio and not separate voicemails (one being the intro from Person A and one being the original Person B voicemail). It seems to hold on to whichever .wav attachment you played first (e.g. if you play the Person B voicemail .wav file and then go to the .wav file that should be Person A's intro, it just plays Person B's voicemail).
    We did not experience this with iOS 6 and have confirmed that things work just fine on phones that have not been upgraded to iOS 7. Email account on iOS devices is a Microsoft Exchange account.
    I am sorry if this is already a known issue, but I've had trouble searching for results. Any help would be tremendous in hunting down this strange phenomenon.
    Thank you,
    -Ted

    Does anybody have even any thoughts on this and whether it might be a known issue of any kind? Anyone seeing this with other .wav attachments outside of Cisco UM  ?

  • RedHat Enterprise Cluster and Cisco IGMP Snooping/Querying

    Has anyone else had any experience with IGMP Snooping/Querying and RedHat Enterprise Cluster?
    We have been experiencing a large amount of problems with this functionality.
    We are running IGMP Querying in our environment and we recently set up a second querier.
    Here's the steps we took
    Existing querier:  192.168.3.248
    Everything was running fine.
    Added a new querier on a different switch: 192.168.3.247
    At this point, all of our RedHat Enterprise Clusters fenced themselves and needed to be restarted in order to restore
    access.  In order to restart the RedHat Enterprise Clusters, the physical servers must be rebooted.
    Are there any known issues with RedHat Enterprise Clustering and Cisco Switches (3750
    series)?  I would expect the querier change to be seamless, but it does not seem that this
    is the case. 

    Hi,
    In our organizaiton we have Red Hat Cluster with 2 cisco switch (Model: cisco WS-C2960S-24TD-L, Version: "flash:/ c2960s-universalk9-mz.122-55.SE3/c2960s-universalk9-mz.122-55.SE3.bin").
    - We are using HP Chassis c7000 and Server is on the chassis. There are 2 service IC & Med. Each server has one service primary and other secondary running.
    - The two cluster switches are connected each other with Ether channer trunk (1+1) link. Also these 2 switches are connected to our Mgmt switch for Server Admin access to HP Chassis via OA port. The Red Hat system has cluster lan (pri & sec) & OA lan (01 & 02 of HP chassis) connected to Cluster switches. The Mgmt VLAN is 501 - 172.31.10.0/24.
    Problem:
    When the CluserSW01 goes down the cluser shifted to CluseterSW02 with Cluser_Secondary_LAN and OA2. But when the ClusterSW01 switch comes again than the communication breaks and cluster don come up.
    I was thinking this is either STP or IGMP, well sure though. As these are production systems hence we also couldn't do much more test as well.
    If you have face any such issue or have experience with it or know what the problem might be... kindly share with me.
    Thanks,
    Adnan

  • Strange behavior with 3560s and RPS 2300

    I just installed an RPS 2300 in a small branch office that has a pair of WS-C3560-24PS switches.  There are two odd things I'm noticing:
    1) When I do "show env rps", it shows the RPS detected but I don't get any information about it.
    Switch#show env rps
    SW  Status          RPS Name          RPS Serial#  RPS Port#
    1   Active          <>
    2) When the switch loses power it fails over to the RPS just fine, but does not fail back to regular power automatically.  I have to unplug the RPS. 
    I've installed same model RPS with a pair of 3750-Es switches, and in that case, "show env rps" from the switch shows me the RPS information, and failback happens when regular power is restored.
    Is there something different about the 3560s, or did I miss something in the configuration?  The switches are running 12.2(55)SE7, IP Services.

    Yes, just found via searching automatic failback is only supported on the 3560-E and 3750-E.
    https://supportforums.cisco.com/message/3669961#3669961
    Also noticed the "power rps" commands are only supported on the 3560v2, so those won't work for me.
    http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/12-2_52_se/command/reference/3560cr/cli1.html#wpmkr11908996
    What's funny is while the exec commands don't work, the config-mode commands do. 
    Switch#power rps name serialnumber
    Can not execute cmd on legacy switch 1
    Switch#conf t
    Enter configuration commands, one per line.  End with CNTL/Z.
    Switch(config)#power rps deviceid serialnumber
    Oh well.  I've been wanting to replace the 3560s with 3750Gs, so this is yet another reason to do so!

  • RPS 2300 and 3825 router.

    Hello I have an RPS 2300 connected to the front of a 3825 router. When the main power (internal power supply) of the 3825, it stays on after switching to the RPS 2300 power, but if the internal power supply of the 3825 gets its power back, it does not switch back. How do I make it switch back to its internal power with out rebooting the router?

    Hi,
    I'll quote from the manual:
    "The switch connected to the RPS 2300 might restart when it changes from RPS power to its internal power. We recommend that you first divert switch traffic to an alternate switch to avoid data loss. This does not occur on the Catalyst 3750-E or Catalyst 3560-E switches."
    It's not very impressive when a vendor says something might restart, and this certainly isn't what you wanted to hear, but it looks like that's the way it works.
    HTH
    Andrew.

    I am confused. Do you mean you found the music, not the tones, or you can't find either?
    If the former, then this is normal. You can't redownload tones from the Cloud.
