Cisco Switching/Routing :: Calculating 4500X Power Consumption Requirements To Select Appropriate UPS Systems
Jun 2, 2013
I am calculating Cisco 4500X power consumption requirements to select appropriate UPS systems. I have 4500X switch with dual power supplies.which value should I take for power consumption calculation, in data sheet it has two values: AC Power Max Rating: 750W System Power Consumption: 330W nominal/400W max
Which values should I take, to calculate UPS systems capacity? And also I am interesting when 4500x has two power supplies what is power consumption?

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.

We are planning for the office move and I need to estimate how much power we need to run a fully populated Cat4507R switch. The chassis include 2 Sups, one 6-port fiber line card, two 48-port Gig and two 48-port FastEthernet line cards. The switch also has redundant power supply (4200ACV 1400W). According to Cisco Power Calculator [URL], I need 49.5 amp 110-120V circuit. It seems to be too much higher than real world. How many 20amp circuit we would need when all the ports are fully utilized?

What is the power consumption of the 6-port 40G M2 module for the NExus 7K?
It says "TBD" on the data sheet for the M2....and it says nothing about power for the Supervisos.
I need to know what the power draw is on a 7009 chassis, with 1 SUP and 5 of these cards....

I have 2 x 3560e-24td-s
2 x ASA5510
2 x 2821(no modules)
2 x 2901
I'm trying to figure out power draw in Amps for my new cabinet. I looked at the data sheet for the 2821 and it says 3A for the 110V under the row AC Input Current, Would that be accurate if I did that for all the models and then just added up the total?

We implemented WLC 5508 software version 7.3, with 8 Aironet devices, most of them are AIR-LAP1131AG-E-K9, and two AIR-LAP1242AG-E-K9.I could really have benefits of VLAN select feature, but I noticed that it's not working like it should. Two interfaces are in Interface group, but from 45 clients only few of them has IP address from one subnet, others have from second sub.I see requirements for this to work is 32 MB of flash on LWAP devices..I only have 16 MB.. upgrade of flash on devices or something ?

My ASA 5505 getting pretty hot after a while and so I used a wattmeter to find out what´s happening.
260 watts is quite a lot if the device is running in idle mode and has no active device attached nor any config has been installed.
What's your experience of the ASA 5505 power consumption ?

We are replacing two 3750E switches with 4500X using cat4500e-universalk9.SPA.03.03.02.SG.15111.GS2
1. is there a command reference available for this ios - can't seem to find out
2. Im using GLC-T gbics and we normally would set the speed to either 100 or 1000 now that option does not seem to be available.
3. when I entered username etc. I got a message " CLI deprecated soon".

regarding the power requirements. I have this Cisco 6503-E switch and I need to know what I need in terms of power.
The manual says if using 120VAC, I will need 16A. If using 230VAC, the unit will require 8A.
I have 2 dedicated 20amps circuits both at 120V. Am I correct on plugging each of the power supplies of the cisco unit to each of these circuits?
Another question will be, do I really need to dedicated 2 dedicated 20amps circuits for the unit? Can't I just use one dedicated 20amps circtuis and connect both power supplies to it?

How to configure a 4500X with a GLC-T SFP so that it will work at 100M.The data sheets say it will work at 10/100/1000 but Im not seeing that happen can't set the speed and it doesn't negotiate with anything at 100M it will only work with auto to another switch set to auto and supports 1000M.

im currenly configuring a 4500X with 16 port. All sfp are 1Gig, but when I input show ip int brief, it shows that the interfaces are on 10 Gig. Does Catalyst 4500X already support the 1Gig SFP without inputting a command or do I have to configure it to activate the 1Gig interface?

Are all ports on Catalyst 4500X Gigabit/10-Gigabit or just the ports on 8-port module. We are looking at 4500X for campus distribution layer but need Gig ports to access switches for now and may year from now will be using 10G.

I'm trying to figure out how to (or if I can) setup the management interfaces (fa1) on a couple of new 4500X switches. My issue is that the 4500X's themselves are the gateway for my management VLAN (.1 HSRP virtual, .2 and .3 SVIs on the pair of switches).
I would like to assign addresses from the management VLAN to the router Fa1 management interfaces but the software configuration guide seems to note this is not supported (and indeed it doesn't seem to work).
Physically I have Fa1 from core-1 into a port on an adjacent switch. Fa1 from core-2 also goes into a port on that adjacent switch. Both are in my management VLAN, whose SVIs are on the cores themselves.

My company is composed of three different campuses, all with a similar network topology. We currently are experiencing high bandwidth on our serial interface at one of the campuses in particular. The network is composed of about 20 VLANS routed internally using a Cisco 6509. Traffic to the outside is PAT’d by an ASA 5510 and then forwarded through our edge router interface. Each VLAN is PAT’d to a specific public address.Due to the PAT, how would you recommend determining what specific private addresses are consuming our resources on the serial interface. When I look at our NMS, it reports the public address, but that only narrows it down to a VLAN. For example, all the devices in VLAN 6 are translated to 146.34.118.245, and 146.34.11.245 is a top talker.

I have probem with symmetric load balancig, in case when both ends of ether channel are on the sam switch (we are using VLAN translation).We need to create L2 port channel with both ends on same switch (Cisco WS-C4500X-24X-ES), for example:Po1 – Gi0/1, Gi0/3 (one end of port channel )Po2 – Gi0/2, Gi0/4 (other end of port channel)On ports in Po2 we will configure VLAN mapping.My question is what is the best ether-channel load-balancing scheme with wich we can accomplish full symmetry in both directions? For example, if traffic in one direction goes through Gi0/1 (member of Po1), in other direction also must go through Gi0/1. This is required because we need to connect four appliances for DPI (they are full L2 transparent) and traffic through each appliance need to be symmetric.
I can set-up src-ip, dst-ip, src-dst-ip etc. load balancing, but, actually I need src-ip on Po1 and dst-ip on Po2. Is there any way to set up different load balancing mechanism for different ether channel on same switch (4500X).

this note is from the 5508 controller config manual, does this apply to 1040 access points in a mesh network?
Note:The recommended power source for MAPs is either a power supply or power injector. PoE is not a recommended power source for MAPs.

We have some ASR WAN routers which have a dedicated 400M interface to a remote site.
Servers on our Local network source the data through some firewalls via 10G interfaces, which connects to 4500X WAN switches then to the Routers on 1G links.
The sources are rate limiting the traffic but the routers are periodically dropping packets which I think is mostly due to burstiness in the traffic between as it traverses through from 10G links to 1G then to 400M.
How to setup traffic shaping on the 4500X outbound port to our WAN routers.I'd like to see if we could buffer and smoothe out the traffic as it exits the 4500X WAN switch 1G port to the WAN Routers.

I have many of these, many models and versions. I have a WRT54G v1, V1.1, V2....V8, I also have WRT54GS's WRT54GL's and others, Lots of other Linksys stuff, almost all of it in the Blue and Black boxes of varing sizes.I have a heck of a time when I reconfigure my network or the wife changes the furniture. I'd love a single document that lists the power specifications and adapter requirements for thens devices... I can't find them any where on the Linksys site. I Have looked and searched and nowhere can I find a consolidate list.
Any have a list of the DC power Specifications, Barrel sizes, and other stuff needed to buy a replacement Power adapter. This page url...lists a lot of information but does not list this critical information... I am amazed that Linksys does not have it listed some where here. Losing a wall wart should not be a reason to pull you hair out, just a simple purchase, If they don't want to stock them, then at least tell us what they are.

I have a requirement to preserve markings end to end across a network utilising 3750X switches, I am marking the packets without a problem, but due to the rewriting function the marking is being overwritten by ther COS-->DSCP maps.To simplify the scenario I have set up a test environment (see Diagram) and am using ICMP as a simple test using ICMP to test with Both 3750 have 12.2(35)SE5 3750-1
mls qos
mls qos rewrite ip dscp
ip access-list extended ICMP
permit icmp any any
Class-map ICMP
match access-group name ICMP
[code]....
I have used wireshark to verify that the packets are being marked, with the' mls qos rewrite ip dscp' they are, without rewriting does not occur.Moving my sniffer to the 3750-2 I am monitoring the Layer3 connection (marking preserved), however on the layer 2 trunk the marking has been reset to 0 , if I remove the 'mls qos rewrite ip dscp' from 3750-2 then I see the marking on the layer 2 trunk, however I am then unable to remark anything generated on this switch. I believe with the 'mls qos rewrite ip dscp' enabled the L3 to L2 transistion removes the IP DSCP sets the COS to 0 and themnthe COS to DSCP mapping ensures the DSCP is set back to 0.I have tried implementing additional marking policies on 3750-2 but to no avail.What I need is ensuring that that a frame / packet marked in 3750-1 can keep it's marking to the end system over layer 3 and a layer 2 trunk. The only place I wan t the marking to be stripped off is when the dot1q tag is removed as it goes through an access port.

I need to choose router for my network. I don't have any special need, besides Internet connection and DHCP for some guest clients.There are around 30 IP phones (static IP), 30 PCs (static IP), and 10 wireless APs (users get dynamic IP). Maximum load is 5 phones, 5 PCs and 20 phones/laptops connected via wi-fi.
I guess I should go for Cisco 800 series. Would model 861 be good or I will need 881 or even 891?
