HP AA-RW20A-TE Device scan, Changing port types, Changing port speeds

Changing port speeds

The 1-Gbps/2-Gbps/4-Gbps ports are capable of transmitting and receiving at 1-Gbps, 2-Gbps, or

4-Gbps. The ports can be configured for either transmission speed or to sense the transmission speed of the device to which it is connected. Table 25 describes the port speeds. To change the port speed, perform the following procedure:

1.Select one or more 1-Gbps/2-Gbps/4-Gbps ports in the faceplate display.

2.Select Port > Port Properties.

3.Select the option that corresponds to the port speed you want.

4.Click OK to write the new port speed to the switch.

Table 25 Port speeds

State	Description
Auto-Detect	Matches the transmission speed of the connected device. This is the
	default.
1Gbps	Sets the transmission speed to 1-Gbps
2Gbps	Sets the transmission speed to 2-Gbps
4Gbps	Sets the transmission speed to 4-Gbps

Changing port types

The ports can be configured to self-discover the proper type to match the device or switch to which it is connected. Table 26 describes the port types. To change the port type, perform the following procedure:

1.Select one or more ports in the faceplate display.

2.Select Port > Port Properties.

3.Select the option for the port type you want.

4.Click OK to write the new port type to the switch.

Table 26	Port types
State		Description
F_Port		Fabric port — supports a single public device (N_Port)
FL_Port		Fabric loop port — self discovers a single device (N_Port) or a loop of up to
		32 public devices (NL_Port). The default internal port type.
G_Port		Generic port — self discovers as an F_Port or an E_Port
GL_Port		Generic loop port — self discovers as an F_Port, FL_Port, or an E_Port.
		GL_Port is the default external port type. A single device on a public loop
		will attempt to configure as an F_Port first, then if that fails, as an FL_Port.

Device scan

The Device Scan feature queries the connected device during login for FC-4 descriptor information. Disable this parameter only if the scan creates a conflict with the connected device.
