Configure Switch Network Information; Changing The Switch Address - HP StorageWorks Installation Manual

Configure switch network information

The Edge Switch 2/24 is delivered with the following default network addresses:
• MAC address—The media access control (MAC) address is programmed into FLASH memory
on the CTP card at the time of manufacture. The MAC address is unique for each Edge Switch,
and should not be changed. The address is in xx.xx.xx.xx.xx.xx format. The xxx is a
hexadecimal pair.
• IP address—The factory preset default Internet Protocol (IP) address is 10.1.1.10. The default IP
address is also 10.1.1.10.
If Reset Configuration is selected from the Element Manager application, the Edge Switch resets
to the default address of 10.1.1.10.
If multiple Edge Switches are installed on the same LAN, each Edge Switch (and the HAFM
appliance) must have a unique IP address. One Edge Switch can use the factory-set address, but
the addresses of the remaining Edge Switches must be changed.
• Subnet mask—The default subnet mask is 255.0.0.0. If the switch is installed on a complex
public LAN with one or more routers, the address may require change.
• Gateway address—the default gateway address is 0.0.0.0. If the switch is installed on a
dedicated LAN with no connection through a router, the address does not require change. If the
switch is installed on a public LAN (corporate intranet), the gateway address must be changed
to the address of the corporate intranet's local router.
Verify that the type of LAN installation with the customer's network administrator. If one switch is
installed on a dedicated LAN, network addresses do not require change.

Changing the switch address

If multiple switches are installed or a public LAN segment is used, network addresses must be
changed to conform to the customer's LAN addressing scheme. The following items are required to
perform this task.
• A local workstation (desktop or notebook computer) with:
• Microsoft Windows Server 2003, Windows 2000, Windows XP, Windows 98, or Windows
NT 4.0 operating system.
• RS-232 serial communication software (for example, ProComm Plus or HyperTerminal).
Note that the HAFM appliance may be used for this function and that HyperTerminal is included
in the Windows operating system provided in the HAFM appliance.
• An asynchronous RS-232 null modem cable (provided with the switch).
Perform the following steps to change a switch's IP address, subnet mask, or gateway address:
1. Remove the protective plastic cover from the 9-pin maintenance port at the rear of the switch (a
phillips-tip screwdriver is required). Connect the 9-pin end of the RS-232 null modem cable to the
port.
2. Connect the other cable end to a 9-pin communication port (COM1 or COM2) at the rear of the
maintenance terminal PC.
