Whats is the default ip address of this switch

There is no IP address when the switch ships from the factory. It is set by the user and/or the network by DHCP. If you do not know what the IP address was set to, then you'll need to return the switch ti it's factory default configuration. There should be information in the manual for the switch about the default config.

Procurve switches do not have a default IP address. you must put an IP address on the switch. You can find a manual for your switch at http://www.hp.com

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: 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: 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>.

Reset your router back to it's factory settings by holding the reset button for about 5 seconds. I have provided a list of the most popular router brands. If it does not work you may need to google what your specific model's default IP address/default username/default passwords are, for example search for "Encore ENHWI-2AN3 default IP address" The default login info can change, it can depend on where you obtained your router. If you purchased it yourself from a store then the standard defaults should work. If you obtained your router from your Internet Provider you may need to contact your service provider. It also may depend whether it's an old or new model router as well. And you may need to press and hold the reset button on your router several times before it actually clears. Make sure you have a wired connection then once you have accessed your router simply run the Setup Wizard. Set your SSID as something you'll remember like "Mavericks Network" and your Password can be something like your phone number for example 3109876543

Default IP Address of most routers is given at the back or bottom of the router and it is usually 192.168.0.1 or 192.168.1.1.
The Default Gateway IP address of D-Link routers is (by default) 192.168.0.1

Hope it Helps!

I am not that much clear whether you can change your Ip adress, but any queries regarding Ip-detais can be solved here, http://www.ip-details.com/

The Switch's factory default IP address is 10.90.90.90
with a subnet mask of 255.0.0.0 and a default gateway of 0.0.0.0.
Often set up by rs232 connection
