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 ??

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 9 x 3750x switches with 5-nonPOE and 5-POE. There is a limitation with 4 POE per stack with Stack Power.
Can we combine all 9 to one stack since there are only 4 POE?
Or, is the 4-switch limitation applied regardless if they are mixed with POE and non-POE?
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.

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.

View 7 Replies View RelatedIn 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.
View 1 Replies View RelatedI have a stack of five 3750X's connected in a single stack with the stackwise cables. Within this one stack, I created two power stacks, one power stack has 3 switches and the other has two switches. In each of the separate power stacks, one power stack port on a switch shows "shut", so the power stacks are not operating in a full ring. Is there a way to do a "no shut" on those stacks ports that are shut? IOS is 12.2(55)SE1

This 3750X stack (3 members) has some 100% cpu spikes. Is this bad enough to start tracking down the cause(s) or is this somewhat typical and not a reason for concern? I just took this reading. How can you detemine when the 100% and 80% spikes occurred?

I recently created a stack using (2) 3750x switches. I have three vlans on the stack (1,105,241) Vlan 105 is configured on 6509 core switches with multicasting and are connected to the stack via gigabit fiber. It is working well with clients on the Master or SW1, however clients on SW2 do not participate in multicasting Any client pc that is connected to SW2 vlan 105 does not show up in the "sh ip igmp snooping group" command. I can statically assign a client on SW2 to the mcast groups but but they fail to register on their own. I can take the cable connection from SW2 and plug it into an SW1 Vlan 105 port and it immediately becomes a member of the groups. I can then connect it back to the SW2 port and it disappears from the group membership. IGMP and PIM are configured with the defaults.

way to upgrade the IOS in my stack on 4 3750x switches
View 6 Replies View RelatedI have a stack of three 3750X-24P-S switches. Each switch has two PSU's.If I do a SH INVENT, switch 2 only lists Power Supply 0
If, however I do a SESS 2 onto the second switch in the stack and then do a SH INVENT, it shows both power supplies. Is it anything to be concerned about?
Switch 2 has an interface configured in RSU Standby.Switch 3 has an interface configured in RSU active. The upgrading sequence is : Switch 2, Switch 1, Switch3.The aim of the test is to prove that there is no loss of IP connectivity throught the RSU process.During the RSU process, there are ping between all the computers.
IOS starting version : 15.0-1.SE3
IOS upgrading version (with OVERWRITE) : 15.0-1.SE3 (same version)
1rst step : Switch 2 reboot and come back master but isolated from original stack (switch 1 and 3)
2nd step : Switch 1 reboot, and come back with switch 2 into the upgrading stack.
Issue : at this step :
- Switch 1 put its interface (IP 192.168.5.254) up :
- Switch 3 has not reboot and still has its interface (IP 192.168.5.254) up
=> we have some OSPF adjencies and mac flapping issues : switch 1 and 3 are trying to mount there OSPF adjencies on the same IP. We loss our IP connectivity since step 3 is not over.
3rd step : Switch 3 reboot and come back up in the upgrading stack. The IP connectivity is back, and the RSU process is done.Is that a normal behaviour ?How can we avoid to loose IP connectivity during RSU process ?
I've a situation where I need to add a new 3750x to a existing stack of 3750. [code] When I tried to stack them together, I get a version mismatch error. Is this because of the difference in SW Image? What are my options next ? My ultimate goal is to make the new switch stack correctly with the exisitng switches.

IOS upgrade tried on the stack of 2XWS-C3750X-24T-S , Upgrade was tried to support WCCP on the platform. Current version is Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 12.2(58)SE1, Not able find any IP Plus ios in the site ? Only available are IP base and Universal K9 , Tried upgrading to c3750e-universalk9-tar.122-58.SE2.tar by using stack upgrade method as per document [URL]
Upgrade fails with error :

Why current ios is not supporting WCCP , I hope it is there in the featureset. ( tried "sdm prefer routing" but no success) Does c3750e-universalk9-tar.122-58.SE2.tar will give me wccp support ? What is the issue with my upgrade and how do I do a successfull upgrade ?
We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high. This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure. Below I provided some outputs about how to diagnose it.

I don't see any recommendation in the documentation. The data sheet indicates a single switch is a non-blocking device so I'd think there's no bandwidth advantage like there is when connecting an actual multi-switch stack and needing to close the loop for the full 32 Gbps stack bandwidth.

I have two 3750X in a stack. Each 3750X has one 10Gb uplink to primary core1 and one 1Gb uplink to backup core2 configured in 2 etherchannel groups. The member switch has bad ports, so I need to replace it. I have spare 3750X unit. Is it possible to connect the spare unit to the stack and then move the RJ-45 cables from the member with bad ports to the new member? That way I can minimize servers downtime to just a few seconds..If that would work, then the last step would be to move the 10Gb networking module from old member to the new one, as well as the secondary PSU. Is it doable? Also according to the documentation, all I need to add new member is matching IOS version, correct?

%FHRP group not consistent with already configured groups on the switch stack
I am building a switch stack using 4 48 port 3750X switches that will also have the power stacked. If I install a single 715W power supply in each switch will the stack support 802.3af accross all 48 ports on each switch? My calculations are 48 ports x 15.4W which gives me almost 740W needed which is over hte 715W power supply. I was reading somewhere were it mentioned that in a powerstack additional power can be drawn from the stack. I know this will not work if you are trying to support power on all switches accross all ports but would it if say 2 of the 4 switches are needing to provide PoE accross all 48 ports? If I say we can only use 24 ports per switch for PoE that drops the power need down to 370W which I believe should work. Just trying to get a better understanding of PoE consumption. Would the best solution be to just add a second power supply to each switch?
View 8 Replies View RelatedI have two 3750G switches stacked together however it's not in a full ring configuration:

And as shown below it's obvious which cable is not working:
show switch neighbors
Switch # Port 1 Port 2
-------- ------ ------
1 2 None
2 None 1
It's not flapping - it's like the cable isn't there at all. I'm going to try reseating the cable in there and perhaps an all out replacement if necessary. My question - is there any threat of a reboot of the switch stack or of partitioning of the switch stack by trying to get the 2nd cable working?
i am seeing very high utilization on a random basis on the stack. and the logs indicate me that there is a pattern where there is a stack power cable shows inserted (which was never unplugged) followed by sudden spike in the utilization.
