My cisco 4948 switch is generating the below error,how do i troubleshoot this error.

We are running a small network business and as funs of ciscos we own a some of the 4948s.We are facing an issue with couple of them as we get the below error message
C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED:Insufficient power
supplies present for specified configuration
First thought to replace the power supply didn't actually work as we did that with no result.Power consumption is not an issue as well because all other 4948s work fine with 1 power supply (forgot to mention is 1 power supply in all of them).
we have multiple Video production networks, with Video servers (AVID Unity ISIS) connected by 10GE fiber links to 4948-10GE switches. On almost every of these switches, I see more or less "Sequence-Err" interface errors. We do not currently have a known problem because this, and no other errors are seen. But I would like to understand the error, and therefore I would like to find out, what a sequence error means, what the cause is, and what the impact (to a frame) is?
By the way, it is well-known that the ISIS Video server does generate very excessive UDP data bursts. Maybe this matters? On Cisco doc I did not find an answer. The document "Troubleshooting Switch Port and Interface Problems" does unfortunately not refer to "sequence-err".
Here is an example output:

In my setup , i have one core switch 4506, 3750 access switches and 4948 server switch.i have created the mngmt VLAN in every switch.the problem is i can ping the every device mngmt ip from any internal network,but my server switch mngmt ip i am not able to ping.trunk link is configure between the core and server,access switches.What is the problem with 4948 switch?
View 7 Replies View RelatedI have got a new 48port Cisco catalyst 4948 switch, which I configured as a VTP client and connected to Cisco 3750 which is a VTP Server (this switch is on production network). I connected port g1/0/48 from 3750 to port g1/48 on 4948 through a straight cable and made both ports as trunk port (I also tried through cross cable). The problem is these two switches are not detecting. For testing I connected a PC directly to one of the port on 4948 (making that a switch port) still the LED on switch didn’t glow up. Is there any special command needs to be run on 4948 switches to activate its physical ports?

View 3 Replies View RelatedI performed an upgraded on a 4948 switch and for some reason the switch kept booting with the old IOS. I was not sure if I needed to change the boot sequence but I performed this upgrade on some of our other 4948's and no issues.I eventually deleted the older IOS version and left the latest version on and reloaded switch and now switch only boots in rommon.I managed to configure the ip info and tftp server ip etc and using the following command as suggested in the rommon help, but it keeps coming back saying 'file not found', when I have checked the file does exist in the tftp server and in the tftpboot folder.
See error message below:

I have a switch connect to 2 backbone(BB).
Now i saw the lights when connect to BB1 is not light but i do not know which command will show the root cause or troubleshooting.
I want to know its caused by hardware, physical port or whatever. Any on can sharing the experiences how to show and troubleshooting this issue?
I also checked the connection and port 1g is fine. Show tech-support is alread here.

I am updating the iOS for a 4948 the bootflash is empty so all i can get into is the rommon. There is no option for x-modem. How can I put the iOS onto this device? [code]
View 2 Replies View RelatedWe had to transport one of our 4948 10 GE to another Data Centre and when we got it there and tried to power up its System Status LED was red and we cannot even get console to the device.
We can try to see if the switch is completely dead and needs replacing or is there something we can do to get it back up and running again?
We purchased two new 4948 with two 10GE uplink ports and upgraded the devices to run IOS 15. My 6506 is running Sup 720 with s77233-adventerprisek0_wan-mz.122-33.SXI9. Currently we have 4948's connected to the same 6506's with no problems. Today I tried to add the new switches with new IOS and it caused of of my 6506 core switches to failover. I can't explain why because it was close to start of business and couldn't do much troubleshooting.
Currently we have four 4948 (running IOS 12.2(14) switches running Layer2 connecting dually to each of the two 6506 cores via 10GE fiber uplinks. I tried to add two more to the scenario, again running layer2 and dual-honing them to each of te 6506 switches. there are two 6506 core switches and they run HSRP and spanning tree is manually set to give priority to even vlans on one 6506 and odds on the other 6506. Also the new switches I tried to add did had rootguard applied as well as the uplinks.
We have to get this working and have no test environment to work with. We need to do this late this evening after close of business.
On another note, I have had problems upgrading some of my older 4948's to IOS 15. I followed Cisco's suggestion and upgraded the EPROM first and then the IOS upgrade took on three of the switches that were ordered rather recently. The four that were ordered in one batch will not take the upgrade even following Cisco's instruction and lots of other tricks. Nothing works. Having problems with IOS 15, in general?
I am planning to upgrade Cisco 4948 IOS upgrade. We have few with older code( 12.2(25)EWA7), when issue sh version shows as Catalyst 4000 L3 Switch Software. while newer version of the switch show as Catalyst 4500 L3 switch.
1 Is this/(sh ver output) just because of the Older code ?
My 2 question is according to release note : [URL]
You need to upgrade your ROMMON before the IOS . 2 What is the approximate time it take to do this ROMMON upgrade ?
I have 4948E module switch at customer site and below is the show version output. Image on the switch is not supporting 'AUTO QoS' as i need to enable Auto Qos on it to prioritize Voice traffic. Which image supports Auto QoS feature . Image should have L3 functionality also i mean it should support Routing protocols. I tried to enable auto QoS using by configuring "QoS' globally but no luck...with existing image.

I'm connecting the two devices above and I need an LC to SC fiber cable. It should be pretty simple but I've seen two different types of LC/SC cables - one is 8.3/125 and one is 62.5/125. I believe the 62.5 is an older cable type but when looking at the detail sheets for each of the SFPs I see that both of these support a 62.5 or 50 micron core size.

Looking at the release notes, it states that my version (12.2.54 SG1) does support vrf aware tacacs but the documentation seems to be a bit off because i do not get a server private command option as stated in the configuration doc after configuring a tacacs server group:
