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?
View 2 RepliesDoes 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.
View 1 Replies View RelatedSuppose 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.
View 4 Replies View RelatedI was contacted by a customer today who is trying to configure QoS on a 4500E with Sup7-E. They are running:
cat4500e-universalk9.SPA.03.02.00.SG.150-2.SG.bin
And the 4500 is licensed for enterprise Services. I don't have access to the switch and am looking for configuration documentation and I am not finding the necessary configuration guides.
client originally connects to the 4500E, moves to the 2960s and then cannot connect back to the 4500E.My design is a 4500E (configured for routing) and a 2960s. The 2960s is trunked to the 4500E, no vlan pruning.
Tried;
- shut/no shut port on the 4500E doesn't work
- no result for sh ip arp | i (clients mac) or sh mac address | i (clients mac) on the 4500E
The only way I can get the user back online is removing the 2960s, not a desirable solution as other clients are on the 2960s.

I noted that the Swicth set up automatically 'switchport mode trunk', so i put the command 'swicthport mode access' because i want to connect only a PC. But the status is the same, I can not achieve connectivity. i just want to know how connect a PC in the interface GigabitEthernet1/4 of the supervisor engine of my Switch.
Will there be some pause in traffic on formed ether channel interfaces (4500E switch), when i will change the default ether channel load balancing method to src-dst-port (or any other non-default method)?

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.

VSS will be established over a pair of 40GBASE-SR4 QSFP+ transceivers in each switch.Do we need MTP/MPO crossover cables or straight through cables to connect the QSFPs?Since the two switches are sitting side by side the MTP/MPO cables will be passed directly between the two racks.As a result there will be no intervening fibre fobots used.
View 1 Replies View RelatedAt 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.
When purchasing part number WS-C3560X-48P-L is a StackWise cable included or do I need to purchase that separately?

When I connect the power cord to the AC main, the power supply module on the back shows "AC OK" LED Green but the "PS OK" LED shows Red. I started referring to the installation guide and it told me that "PS OK" LED turns RED when output has failed. Guessing this I checked with another power supply module that was working, but still I get the same LED indicators.The original power supply module works with other switches.IOS crash...?
View 5 Replies View RelatedI got some specs here that I can't seem to match with any existing switch - unless the 350CG-8PC-S can be powered by PoE.Let me quickly put down the important specs.
8x Gigabit ports
2x 1G Copper or 1G SFP Uplinks (It'll be a 1x Copper and 1x SFP setup)
support for PoE passthrough ( so just capable of it, provided it's 2x Copper Uplinks )
Does that match the 350CG-8PC-S ?

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?
