I was wondering if there was a way to disable the RPS in a 3825? When I do a Sho Env All I get the following;
Redundant Power System is present.
RPS is in standby state
Redundant Power System is present.
RPS is in standby state
How ever there is no RPS in the system. At least not that I know of. There is only one power supply.

Does a portable RPS device either from Cisco or another manufacturer exists, that would allow you to move primary power for a switch without causing an outage? I realize that for the Catalyst 3560 for example, you can get an RPS 2300 or 675, but my understanding is that these are made for a more permanent installation, not to mention rather costly.
It looks like the RPS 675 is rather inexpensive after all, especially in the secondary market, but still rather large for toting around.

I know that the 6500 with a Sup 720 reserves power for a redundant 720. If there is no plan to install that redundant Sup, is there a means of releasing that reserved power? I know that one approach would be to insert a card into that slot to cut the reserve down, but I need to reclaim all of that power.

I have a 6509-E with redundant 3000W power supplies (WS-CAC-3000W) but one supply is current non-operational.From the outputs I'm not sure whether the issue is (more likely to be) with the supply to the PSU or the PSU itself, i.e. whether my first action should be to get an electrian to check the supply or fault call the PSU with our maintenance providers and have it replaced?

After stacking two 3750X switches, with four equal power-supply's, with StackWise and PowerStack , still got the next message every few hours %PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding (gn4m-rt1p08-04-2)( note that the message revers to the second switch in the stack ) although the stackwise and powerstack on the switches is oke and are working correctly. !
Config : Stack-power in power-sharing mode/strict With CLI on the switch : All the power supply's and stack-power details, prio look OK.
Only: LMS prime /inventory/cisco-view/configure/power supply status result : some power supply's are marked as disabled.with the command > power supply 2 slot a off/on I manage to get the status back to "normal", but after a few hours some power supply's are again marked as "disabled".
Looks like SNMP en IOS difference from opinion.

We have two switches of the same model (WS-C3560-48PS-S) that are not providing PoE. I'm trying to remotely determine what the cause of the issue is.
Here is some output.

I have a 6500 chassis with 2 power supplies. At the moment I am using the default configuration:
power-redudancy mode redundant
The problem is that an inserted module is in "power deny" state due too insufficient power.
I know, that It's not a good idea to change into combined mode (loss of redundancy), but my customers requested this anyway.
So I will change to combined mode. So here's the 1 million dollar question: "Which modules will go into power deny, if one of my power supplies fails?"
The 6500 config guide states:
"Power supply is removed withredundancy disabled
• System log and syslog messages are generated.
• System power is decreased to the power capability of one supply.
• If there is not enough power for all previously powered-up modules, some modulesare powered down and marked as power-deny in the show power oper state field."
Well, do you know if there's any way to configure some kind of priority? E.g. I definetly don't want by 10Gig Module or WiSM module to be in power deny. Can i statically make sure, those module will be powered on for sure? Like: "power enable module slot_number" How is this calculated? Or is random?

In a stand alone 3750x switch configuration, can the secondary power supply only act as a redundant power supply (active/standby), or can it become a "pool" of power similar to power sharing mode for StackPower (somewhat active/active)? I understand there is no stack involved here but I'm curious if this functionality is possible.

I have the task of replicating the router config on a 3825 router on a 3750 switch. Reason is we are taking out the router and replacing it with the switch to make use of the router for other functions.
Below is main part of the router config:
!
ip source-route
ip cef
!
!
multilink bundle-name authenticated
!
license udi pid CISCO3825 sn FCZxxxxxxx
!
vlan internal allocation policy ascending
[code].....
The 3750 switch I have runs C3750E-UNIVERSALK9-M, Version 12.2(55)SE3 on a LAN BASE license.
The first thing I have done is to order for a license upgrade to IP BASE which would give the support for OSPF routing.I do not see much of an issue with the Interface configs, however, I am not too sure about replicating the routing config on the switch.
My question is can I run the commands as shown for the OSPF routing on the switch? If not, can I get suggestions on how best to set this up on the switch?

I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.

I have a 3825 router that I have setup with the following: [code]
Its on a trunked port to my 3750 switch. I am new to this compnay and havent changed it over to IP routing on the switch quite yet.Both Vlans are setup on the 3750 without an SVI. All hosts on VLAN 1 can ping both interfaces without issue.
If I put a host on the 172 VLAN it cannot ping anything on the router. If I put another host on the VLAN they can ping each other. If I put an SVI on switch the 172 VLAN hosts can ping the switch, but still not the router. ONce I put the SVI on the switch, it can no longer ping the router. I am giving the SVI ip 172.22.1.5/24.
I have verfied with TAC that the trunk is allowing the vlans to the router.
I have been working with TAC. They have asked me to update the code on the switch, but I think they are just punting. [code]

How to replace a defective redundant sup. I read on several articles that inserting new redundant sup should not be an issue as the active sup will always send its configuation to the standby. We are running SSO on the Sup720. Should I switch it to RPR before I install the redundant sup? I read a case wherein they switched it to RPR from SSO before inserting the new redundant sup. My concern is the IOS mismatch since Cisco doesn't always send the same IOS on RMAs.What I am planning is this.
1. Save/Backup configuration
2. Remove the redundant sup on slot 8 (since it is a 6513)
3. Insert the new redundant sup on slot 8.
4. Check if all the configurations were synced from slot 7 to slot 8.
5. Copy the IOS from sup-bootflash to slavesup-bootflash. (if the IOS are not the same)
6. Check show bootvar to see if the boot variables are correct.
7. If bootvar is the same, reload slot 8 to boot the new IOS.
Is this a good plan or am I missing something? I am worried with this document if the redundant sup has a different software. If i insert the card in slot8, according to Cisco, it will revert to RPR. If slot 8 boots and it has a different OS, then slot 7 will switch to RPR even if it's active. Would I still be able to access the slavesup-bootflash of slot 8? Is it going to boot 100%? I read that doing a force switchover will cause a flip and RPR would cause the line cards to reinitialize and I don't want that. Well I am not going to do a force switchover since i want slot7 to be active and retain slot 8 as hot.

I have also configured static route for the local network. However, now I can only ping the GE0/0's own IP from the router. Here are the running-config:

we have 2 Supervisor IV modules in our 4507, i want to upgrade the IOS as its still on 12.2 and i am going to upgrade it to the latest.
my first question is, if i update the IOS on the bootflash will it replicate to the secondarybootflash?
secondly, can i force a reboot of the secondary supervisor, then the primary after the secondary is up? i'm just trying to minimise downtime and get a plan going.
is there a difference in 12 vs 15 that would impact my current config that i should be aware of?
