As far as I know, most HP Switches come with DHCP disabled as default as they are meant to have Static addresses.
I'd suggest you find a console cable..
Tom CieslikIT EngineerCommented:
In the factory default configuration, the switch has no IP (Internet Protocol)address and subnet mask, and no passwords. In this state, it can be managed only through a direct console connection. To manage the switch through inband(networked) access, you should configure the switch with an IP address and subnet mask compatible with your network. Also, you should configure a Manager password to control access privileges from the console and web browser interface. Other parameters in the Switch Setup screen can be left at their default settings or you can configure them with values you enter. Many other features can be configured through the switch’s console interface, to optimize the switch’s performance, to enhance your control of the network traffic, and to improve network security. Once an IP address has been configured on the switch, these features can be accessed more conveniently through a remote Telnet session, through the switch’s web browser interface, and from an SNMP network management station running a network management program, such as ProCurve Manager.
