It sounds as though you may have a failed power supply. If that is the case you will not be getting any response from the device. If you are getting activity (fans spinning, LED activity) then there is a different issue.

Plug a console cable into the device and open up a terminal window (I prefer putty). Make sure your serial settings are 9600 baud, 8 data bits, 1 stop bit, no parity and no flow control. Once you have your putty window open, reboot the device. You definitely should have some activity on your terminal screen during the boot process. If the characters are unreadable, your ASA is set to use non-standard serial settings. In this case, you will have to guess at what they are. When I have seen this in the past, it was due to someone trying to xmodem an image to the device and upped the baud to its maximum of 115200. You can try that.

However, once you get the device to respond via its console cable, you will have more information to determine the root cause of this issue. For example, are you getting errors on POST (power on self test)? Is the device loading into ROMMON (ROM Monitor)? Are the ASICs passing POST? Once you have this information, you can ask about your specific issue here on fixya, or you can search Cisco documentation to find further information.

Furthermore, I always recommend purchasing/renewing your Cisco SmartNet contracts. This will give you access to Cisco TAC and allow you to get parts replacement in case of hardware failure.

I hope this helps.

Try to reset the device again and connect to a different power source.

What is the default ip address for powerconnect 5212


You must assign an IP address to the switch to gain management access over the network. You may also need to a establish a default gateway between the switch and management stations that exist on another network segment. You can statically configure a specific IP address or direct the switch to obtain an address from a Boot Protocol (BOOTP) or Dynamic Host Configuration Protocol (DHCP) server when it is powered on. Valid IP addresses consist of four decimal numbers, 0 to 255, separated by periods. Anything outside this format is not accepted by the CLI program. notice.gif NOTICE: By default, the IP address is assigned to VLAN 1 through DHCP. If you select the bootp or dhcp option, IP is enabled but does not function until a BOOTP or DHCP reply has been received. Requests are broadcast periodically by the switch in an effort to learn its IP address. (BOOTP and DHCP values can include the IP address, default gateway, and subnet mask).
To display assigned IP settings using the CLI:
  1. From the Privileged Exec or Normal Exec level mode, type show ip interface and press <Enter>.

The assigned IP address and subnet mask displays.

  1. From the Privileged Exec mode, type show ip redirects to display the assigned gateway IP address. Press <Enter>.

The following example displays IP settings assigned by bootp or dhcp using the CLI.

Console#show ip interface

IP address and netmask: 10.1.0.1 255.255.252.0 on VLAN 1,

and address mode: User specified.

Console# show ip redirects

ip default gateway 10.1.0.254

Console#
Before you can assign a static IP address to the switch, you must obtain the following information from your network administrator:

  • IP address for the switch

  • Default gateway for the network

  • Network mask for the network

To assign a static IP address to the switch:
  1. From the Privileged Exec level global configuration mode prompt, type interface vlan 1 to access the interface-configuration mode. Press <Enter>.

  2. Type ip address ip-address netmask, where ip-address is the switch IP address and netmask is the network mask for the network.

  3. Type exit to return to the global configuration mode prompt. Press <Enter>.

  4. To set the IP address of the default gateway for the network to which the switch belongs, type ip default-gateway gateway, where gateway is the IP address of the default gateway. Press <Enter>.

  5. To save your configuration changes, type copy running-config startup-config and then press <Enter>.

notice.gif NOTICE: Only one VLAN can be assigned an IP address. If you assign an address to any other VLAN, the new address overrides the original IP address. The following example shows how to set a static IP address using the CLI.

Console(config)# interface vlan 1

Console(config-if)# ip address 192.168.1.5 255.255.255.0

Console(config-if)# exit

Console(config)# ip default-gateway 192.168.1.254

Console(config)#
To configure the switch for DHCP or BOOTP:

  1. From the Privileged Exec level global configuration mode prompt, type interface vlan 1 to access the interface-configuration mode. Press <Enter>.

  2. At the next prompt, use one of the following commands:

    • To obtain IP settings through DHCP, type ip address dhcp

    • To obtain IP setting through BOOTP, type ip address bootp

  3. Press <Enter>.

  4. To save your configuration changes, type copy running-config startup-config, and then press <Enter>.

Need to replace drum belt


Most dryers have a tensioner pulley that the belt needs to go around to keep it tight. The belt goes around the motor pulley and the drum, but it goes around the tensioner pulley in a way that would keep it tight (you also need to release the tension on the tensioner to get the belt around it) If there's not a tensioner pulley there has to be some other means of putting tension on that belt, look around the the other pulleys that the belt goes around.
