Cisco Switching/Routing :: C3750X Stack Power Cables End Colors
Oct 26, 2011
Does the color strips on C3750X stack power cables mean anything, I mean the green and yellow ones. On all Cisco pictures the green one seems to be plugged in the upper ports. I asked local Cisco representative, but he seems not to be sure. We tried to try different scenarios, and it looks like it does not matter what cable end we use. We do not have any external power supply, only interconnecting C3750Xs.
Any issues are reported while configuring power stack ? We did several times with 12.2.58SE1 and SE2, sometimes the power stack is created automatically, sometimes needs to be configured manually. Looks like the behavior is not the same. Maybe it depends on the number/type of switches and number/type of power supplies.
can i stack cisco (ws-c3750G-12s) with (ws-c3750X-24p-poe-s) with (ws-c3750-48p-10/100 poe) i mean even a switch is 10/100 and the other switch is 10/100/1000?
I am having an issue with adding a c3750x switch to an existing switch stack Currently there is 2 x WS-C3750X-48P and I am trying to add another WS-C3750X-48P to this switch I have cabled the switch to the stack using the stack cables and added the command to provision the switch on the exisitng stack. However when I turn the switch on it just goes on its own stack.
I noticed the new switch had a later version of IOS so have downgraded this to the same version as the other switches but still no joy Here is the sh ver from the exisitng stack

We have WS-C3750-24FS switches stacked supporting users on our LAN. I want take advantage of the netflow capabilities of the WS-C3750X using the C3KX-SM-10G card.
Would I be to see netflow data coming from the WS-C3750's if I stacked it with the WS-C3750X?
Also I read that the C3KX-SM-10G card would support a 1G SFP is that correct?
I have two WS-C3750X-48T-S which is "IP BASE" licensed, which are connected as stack.I need to use Policy Based Routing (PBR) to direct Vlans to two different gateways, and command "ip policy route-map" which is supported only in C3750-IPSERVICES license.Do I need upgrade only master switch with Cisco IOS IP Services - product upgrade licenseMfg. Part#: L-C3750X-48-S-E, or both switches need to be upgraded?
At a customer i've tried to add a new 3750 switch til a running stack.I used the following proccess:
1. connect stack cables to the new switch
2. bootup new switch.
Normally the new switch will become a member of the stack, but here, the switch says its the stack master. I can see that the stack port from the old switches connecting the new is up.The only way i could make it work was to provisioning the new switch as switch nr x, save, power off and then connect it and boot it up.The IOS i the same on all switches.
I have 3 switches in my 3750 X stack. I am getting the following error in the logs: %PLATFORM_STACKPOWER-4-PRIO_CONFLICT: Switch 1's power stack has conflicting power priorities. Not sure what I should do next. Below is my Stack-power configuration:
Power stack name: Powerstack-1 Stack mode: Power sharing Stack topology: Ring Switch 1: Power budget: 735 Low port priority value: 20 High port priority value: 10 Switch priority value: 2 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: c464.1308.7900 Neighbor on port 2: e8b7.4827.e680 Switch 3: Power budget: 729 Low port priority value: 22 High port priority value: 13 Switch priority value: 4 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: 2894.0fd9.9f00 Neighbor on port 2: 2894.0fd8.e200 Switch 2: Power budget: 690 Low port priority value: 21 High port priority value: 12 Switch priority value: 3 Port 1 status: Connected Port 2 status: Connected Neighbor on port 1: 2894.0fd8.e200 Neighbor on port 2: c464.1308.7900
Each switch has its own 715W power supply in it and all check out OK.
Cisco let us try a CISCO C3750X- 24T-S Stack (2 switches) ->> IpBase Sofware licence We've 2 Hyper-v 2008 R2 and one SAN Netapp FAS2040 connected via Iscsi.All was working well with this stacks.Hyper-V see Nas Iscsi interface without problem. Even with basic stack config (no Vlan, ect...).Then, after this test period, we bought a C3750X-24T-L stack (2 switches) to replace the stack lent by Cisco.This one is LanBase Software.
With this stack, hyper-v work very bad ! We've got a lot of Iscsi error in the eventvwr.I can't access luns.So, is there a difference between LanBase and IpBase for a iscsi use ?I put the 24T-S config on the 24T-L switch without pb. So config is the same on both stacks...Also i've got a "TestPortAsicLoopback" = "Failed" on the new stack...I've tried with other stack cables. Not better.
I have changed the universal IOS on the 3750X to IP base..but they still wont come up as a stack. On the 3750X I don't see any log entry, on 3750G (major version mismatch).
Just received a couple of new 4500e chassis with the 2800ACV power supplies installed. I have not seen the cables they come with standard, the plug ends are considerably thicker than normal, what is the deal, do we need an electrician to come out and rewire or purcahse new powerboards?

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".
I have a couple of WS-C3750X-48T-L and a couple of WS-C3750X-12S-S, I want to stack all four of them together into a single stack. WS- C3750X-12S-S are running c3750e-universalk9-mz.122-58.SE2 whereas WS-C3750X-48T-L are running c3750e-universalk9-mz.122-55.SE3.I have got a couple of queries as under:What are the options to achieve putting all these 4 switches into a single stack? Can the LAN Base switches upgraded to IP Base?
I want to chose the right UPS product for 7 x WS-C3750X-48PF-L in one stack. The Cisco data sheet says 1100W AC, however, I am only connecting 20 IP Phones, each phone will consume around 12.2 Watts.
So in this case, How many watts would I need for the whole 7 switches in the stack ?
in other words, only the first switch in the stack will be connected to 20 IP Phones, but the remaining switches in the stack will be Data Only thought the remaining switches in the stack are capable of delivering a full PoE.
the power consumption of the WS-C3750X-48PF-L with only data connected to it.
Suppose I have a 3 member stack of 3750x switches. Members a, b and c.I have all 3 members stacked with all 3 *data* stacking cables in a daisy-chain topology. The 50 cm data stacking cable from switch a (on the very top) to switch c (on the very bottom) just barely reached.Of course, that means the 30 cm *power* stacking cable didn't reach between a & c. Right now, the power stacking cable goes from a to b, and then another cable from b to c. Leaving me with a useless extra 30 cm power stacking cable.
My question is, can switch "a" receive power from switch "c" through switch "b"? Is this just a big electrical "bus"? What if the power supply in switch "b" is removed?Just wondering if there is a need for me to get a longer power stacking cable (one of the 150 cm power stacking cables).
I have a customer that has a stack of 3750x switches installed in production and now would like to install the powerstack cables. The switches are in production and downtime would like to be avoided. Can you install the powerstack cables with the switches powered up? I would assume you can, but wanted to verify before doing so.
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 ??
I have 4 switches in a 3750-X stack.Here is the output from the stack why are the switches out of order and I'm not able to bring up switch 1 port 1.
switch 4 port 2 shows not connect it is I've checked the cables.

Symptoms: The switch hangs - after a hard reboot and after two hours switch No. 2 flew out from the stack. After the reboot, everything returned to normal and now when a few days passed switch works without problems. Devices: WS-C3750X-24T-S
I have running a Stack with two C3750G-24TS-S1U with the IOS c3750-ipbasek9-mz.122-50.SE3.Now I want put a new C3750X-24T-S in the existing stack. I have read this is possible. I have running a other mixed stack with a C3750G-12S and an C3750E-48TD. Its running fine until I want to make an IOS update. The update was done with the CW LMS 3.1. After the automatic update and restart only the C3750E had an new IOS the C3750G doesn't have any IOS. Do I have the same problem with the mixed Stack C3750G and C3750X?Do I have to upgrade the IOS by copying the different IOS Versions ( c3750-ipbasek9-mz.122-50.SE3 / c3750e-ipbasek9-mz.122-50.SE3) to every switch ?
We are trying to monitor two stacks of CISCO WS-c3750X running IOS 12.2.(58)SE.
We can get the state of the power supplies, but after a power cycle or reboot of the switches the identifier of ONE of the Power supplies ALWAYS change. The OIDs for the rest of the PS do not vary. The problem happens in the two stacks.
