Hp Serial Port Adapter Pinout

Usb Serial Port Adapter

Pinouts are uncertain too -- trying to avoid having to add a null-modem style adapter just to swap DTE/DCE, and I haven't been able to figure out a DTE/DCE designation for either the HP side or the Cisco port. The console port is an RS-232 serial interface that uses an RJ-45 connector to connect to a management device such as a PC or a laptop. If your laptop or PC does not have a DB-9 male connector pin and you want to connect your laptop or PC to the device, use a combination of the RJ-45 to DB-9 female adapter along with a USB to DB-9 male adapter.

Connecting a management console

The switch has a full-featured, easy to use console interface for performing switch management tasks including:

Monitor switch and port status and observe network activity statistics.
Modify the switch’s configuration to optimize switch performance, enhance network traffic control, and improve network security.
Read the event log and access diagnostic tools to help in troubleshooting.
Download new software to the switch.
Add passwords to control access to the switch from the console, web browser interface, and network management stations.

NOTE: After installing and power up the switch, to use a networked (In-band or out of-band) connection to manage the switch, user can use the out-of-band console connection to minimally configure the switch with an IP address and subnet mask. By default, the switch is configured to acquire an IP address VIA DHCP. See “HP 2920 Switch Series - Minimal Configuration Through the Console Port Connection ” onpage 3-2 for more information.

To connect a console to the switch, use the RJ-45 console cable shipped with the switch. Hp scanjet 8250 driver windows xp. Alternatively, user can use a USB cable (Not supplied) for a console connection. (See USB Console Port Notes below.) Connect a PC or VT-100 terminal to either of the Console ports. The connected PC or terminal then functions as a management console connected directly to the switch.

The switch can simultaneously support one out-of-band console session, through one of the console ports, and in-band Telnet console sessions. The console ports are used only for out-of-band management, not for Telnet sessions.

USB console port notes

USB Console Port Driver Download
When using the USB console port, the connected PC first requires virtual COM port USB drivers tobe installed.
USB drivers are available for Windows XP (SP3 or later), Windows Vista(SP2 or later), and Windows 7 (SP1 or later). The drivers can be found onthe HP Web site at Click here to access HP Networking support website. On that web site, follow these steps:
1. Type users product model (For example, 2920), or product number in the Auto Search text box.
2. Select one of the switches from the drop down list.
3. Click the Display selected button.
4. From the options that appear, select Software downloads (On the right-hand side). Then, download the USB Console Port Drivers and Information.
Users PC’s operating system may also automatically find the correct driver when it detects the switch USB connection.
USB Console Port and RJ-45 Console Port Interaction
Note that user cannot use both the RJ-45 and USB console ports at the same time.By default, the RJ-45 console port is active (To allow remote access to the switch VIA a terminal server). But, when the USB console port is connected to the switch and then to a live PC, it takes priority over the RJ-45 console port and becomes the active port. If the USB console session is closed by the inactivity timer, though, the RJ-45 console port becomes active again.To reactivate the USB console port, make sure that the USB console cableis connected to a live PC and then simply unplug it from the switch and then reconnect it to the switch. If desired, user can configure the inactivity timer to a longer time VIA the terminal emulation program that user are using.

Configuring the management console connection

To configure a console to manage the switch through the console port connection:

Configure the PC terminal emulator as a DEC VT-100 (ANSI) terminal, oruse a VT-100 terminal.
Configure the terminal with the following settings:
- A baud rate from 1200 to 115200 (The switch senses the speed)
- 8 data bits, 1 stop bit, no parity, and flow control set to Xon/Xoff
- For the windows terminal program, disable (Uncheck) the 'Use Function, Arrow, and Ctrl Keys for Windows' option
- For the Hilgraeve hyper terminal program, select the Terminal keys option for the Function, Arrow, and Ctrl Keys act as parameter

If user use a management console with different configuration settings, be sure to reconfigure the settings on both the terminal and the switch in the following order so that both configurations are compatible:

Reconfigure the switch and save the new settings.
Reconfigure the terminal and save the new settings.
Reboot the switch and re-establish the console session.

Setting up a console connection

To access the switch through an console port (Out-of-band) connection, follow these steps:

Configure the management console as described above under 'Configuring the Management Console Connection'.
For a direct console connection, connect the PC or terminal to the console serial port using one of these console cables:
- A DB9-to-RJ45 cable (Shipped with the switch).
- A micro-USB cable (Not provided).
  For the situation wherever the file is saved, check the pc settings. Download the file. Double-click the downloaded EXE file to decompress it, then installation can begin automatically. Download / Installation Procedures 1.
