Cisco Switching/Routing :: Can Mix Power Supplies Of Different Wattage On 6500
May 14, 2012
I have 6500 core switch with 2500W power supply, and I want to install a second power supply with 3000W ? is this applicable ? if yes, is there a specific configuration that must be done ?
211540: Jun 10 10:45:17.935 UTC: %PLATFORM_STACKPOWER-4-UNBALANCED_PS: Switch 4's power stack has unbalanced power supplies 211541: Jun 10 10:46:18.045 UTC: %PLATFORM_STACKPOWER-4-UNBALANCED_PS:
I just upgraded my power supply's from 2500Watts to 4000watts, however the show power still shows 2500watts.how do i make the 6513 recongize the change? I do have 250volts at 30 amps connected to each power supply.
system power redundancy mode = redundant system power total = 2331.00 Watts (55.50 Amps @ 42V) system power used = 1741.74 Watts (41.47 Amps @ 42V) system power available = 589.26 Watts (14.03 Amps @ 42V)
I have two WS-C3750X-48PF-S in stack, but every one has just one power supply. In the package of the switches is included one stack power supply cable.does it make sense to use stack power cable if every switch has just one power supply ??
Are the power supplies on these switches interchangeable? I know the model numbers are the same with the exception of the /2 at the end if it. Customer wants it to have a dual power supply but not sure if I need to order a secondary powere supply or just another powere supplu from a spare switch.
If I'm upgrading dual redundant power supplies in a Catalyst 4507 from 1000W (data) to 1400W (data), can it be done without taking the switch through a power cycle? I'm guessing no as I read that the switch will not recognize a 1400W PSU in bay 2 if there is still an original 1000W PSU in bay 1.
We just purchased a Nexus 7010 switch and we are at a stand still with our COLO trying to figure out what power source should be provided. APC recommends a 50amp 3phase vertical cabinet PDU (AP7867). What type of power sourcereakers will be sufficient in handling the Nexus 7k /w (3) power supplies? Do the COLO need to provide single phase or 3 phase power recepticals?
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?
We have two 6500s. One is running in power redundant mode and the other is running in combined mode.We need to change the one running in combined mode to redundant mode to ensure it can run ok on one supply if needed but I have a couple of questions.
1. Assuming that we are not oversubscribed on the power allocated, does changing the mode cause any disruption?
2. The switch running in combined mode seems to have allocated some power for an "Inline Local-Pwr-Pool" which is not allocated on the switch running in redundant mode (see attached). Does this allocation will be needed if we change the power mode?
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.
We are having troubles getting a 10Gig interface to come up with a carrier... it shows down down.We are using X2-10GB-LR on a 6500 and SM fiber, distance to carrier hand off is about 90 feet.
According to: [URL] The receiver power on a X2-10GB-LRis Max 0.5 Min -14.4
Our carrier is sending at +5db. Currently the interface is down.
My question is; would the interface even come up if it is receiving a powerful signal?
Here is DOM output for our interface.

Cisco IP phones attached to a Moduke in one of my Cat6500 access Switches suddenly went down. Upon closer inspection of the Switch Sys log, I observed the following Sys log error messages: [Module 9 is experiencing the following error: Inline Power Module - PS Voltage bad. ]A sh Mod output indicates the PoE daughter card and Main Module are "ok" - see attached output. It appears issue is related to the the actual Power Supply module and not the blade module and installed PoE Daughter card. I am inclined to open a TAC case for a PS replacement, but wanted to see if this can be resolved without a hardware replacement. At this time all 48 IP phones attached to this module are out of Service.
The following discussion is based on cisco cat 6500 switches with two power supplies: p1 and p2. . Both power supplies are running in combined mode .Each power supplies is rated with 500 watts max( I just picked 500 watts for simplicity)Combined mode In combined mode, each power supply provides approximately 83% of its capacity to the chassis. This allows for greater utilization of the power supplies and potentially increased PoE densities
1) Let say our specific 6500 switch's configuration requires 1000 watts. We have two power supplies p1 and p2 ,each with rated power of 500 watts. Both power supplies must operate in combined mode. Will power supplies be able to meet the total load power requirement of 1000 watts?
Here is my understanding :The maximum power delivered by each power supplies is 83 percent of its rated power, assuming power supplies are running in combined mode.
So Maximum power delivered by power supplies
= 83% of p1+ 83% of p2 = 83% of 500 + 83% of 500 = 415 +415 =830 watts
Thus the required load of 1000 watts can not be met by our power supplies in combined mode.
2 )Suppose our switch's switch configuration needs 500 watts. Again our power supplies each rated with 500 watts, are configured for combined mode. How much power is being delivered by each power supply? Is it 83 percent of the total load i.e 500 watts?
can I plug power supply from 4500 to 6500? more specifically we have power supply PWR-C45-1300ACV. And we need to place some power supply to 6500, which has only one active module. So 1300 should be enough for it. But we dont know if they are physically compatible, if it is possible to plug. I didnt find this power supply to be officially?
I am getting the below messages on my Cisco 6500 series switches every 1min. The IOS version is 12.2(33)SXI6 & with SUP32-GE-3B
%ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD %ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD %ILPOWER-7-DETECT: Interface Fa1/1: Power Device detected: Cisco PD
These messages are I am recieving on few ports only not on all port having IP Phone connected. I tried changing the phone to some other model but that also did not resolved my problem. Also I tried powering on the phone using power adapter but the issue still persist.
Client are not facing any issues due to this error, but still I would like know what can be the issue which is generating these logs.
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?
CISCO 3945 Routers - Are the 3945 Router power supplies load balanced by default? We are trying to determine if our switch/server rack at our remote location has maxed out it's power load requirements. I just need to know if the 3945 power supplies load balance by default or if the redundant power supply is ON but not really providing the router with power and is just there incase the other power supply fails .
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".
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.

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 want to get a Cisco router for central point of 100 GRE tunnels and total 10G traffic coming from those tunnels. I used 6500 but its CPU became high in less than 2 G traffic. Can you identify me a suitable router for this purpose. I think the router must process the GRE in hardware.
As per my understanding 6509 all slots are dual channel, so 9 slot * 40 per slot (20 g in and 20 g out) = 360 GB How cisco claim the 720 ?? What about the 6513 chassic switch fabric connection?
I am seeing a strange situation on my 6500 switch?By having snmp walk on '1.3.6.1.4.1.9.9.109.1.1.1.1.3' (== cpmCPUTotal5sec), I came to know that there are two processor and the cpu util for switching processor is gone to 88 % and some time creeps to 99 %.
snmpwalk -v2c -c "removes" sw6500 '1.3.6.1.4.1.9.9.109.1.1.1.1.3' SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.1 = Gauge32: 12 (--- this is for CPU of Router Processor ) SNMPv2-SMI::enterprises.9.9.109.1.1.1.1.3.3 = Gauge32: 99 (--- this is for CPU of Switching Processor )
but when I do sh process cpu on the console, all looks normal as it shows cpu utilization of RP. why the value is so high on the switching processor ?
For intervlan routing, Is 'IP routing' command enabled by default on a 6500 series switches based on the IOS?and on 3750 switches, do we need to enable the "ip routing" command manually for intervlan routing?
I'm looking to restrict Inter-VLAN routing through L3 switch (cisco 6500) and wanted to know best possible way to do it. I used VACL and achieved success to some extent, but my config is making clients take up to 5-6 mins to authenticate IP address from the DNS (bootps).My VACL config was as follows:
Subnet to restrict is 10.100.15.0 (VLAN 15) STEP 1: Created extended ACL to allow bootpc/bootps through DNS ip access-list extended EACL_DNS permit udp any eq bootps any permit udp any eq bootpc any
STEP 2: Created standard ACLs to allow only relevant subnet, server VLANs & some IPs from other subnets for printers/scanners etc.
ip access-list standard SACL_VLAN_15 permit 10.100.15.0 0.0.0.255 (the subnet I'm restricting) permit 10.100.50.0 0.0.0.255 (server VLANs) permit 10.100.25.45 0.0.0.0 (printer in another VLAN which has to have access in VLAN 15)
STEP 3: Created VLAN access list
vlan access-map VACL_15 10 match ip address EACL_DNS action forward vlan access-map VACL_15 20 match ip address SACL_15 action forward
STEP 4: Applying VLAN Access list on VLAN 15 vlan filter VACL_15 vlan-list 15 Though the above works, below is noted:
1. I'm still able to PING 10.100.15.2 (the switch virtual interface) from outside the subnet, which I don't intend to do so. Howeve all cients in the subnet have no connectivity from outside the VLAN 15.
2. As mentioned its taking quiet some time to negotiate with the DNS server at system boot time.
I have a power conncet 6224 with routing enabled with several VLANs setup.VLAN Database: 6,8,10,90-254VLAN 6 is our management vlan10 is for our core network services (DNS, Domain, Exchange etc)90-254 are isolated vlans.What I need to accomplish is to prevent vlans 90-254 from communicating with each other and only allow communication to VLAN 10 and the internet. All internet firewall work will be handled by our Sonicwall. [code]
I used to "ip routing" command in order to enable inter-vlan routing, for example with 3750 cisco. I have a 6503 cisco with SUP720 MSFC3. I was able to create some vlans but I can not configure inter-vlan routing.

For intervlan routing, Is 'IP routing' command enabled by default on a 6500 series switches based on the IOS?hes, do we need to enable the "ip routing" command manually for intervlan routing?
