J8766A, J8768A, J8776A, and J9033A)
Note
You can install, exchange, or remove modules after the switch has been powered on. Whenever a module is
installed during this process, it is initialized and tested for correct operation. During this process, the switch
Self Test LED is on. If you hot swap another module while the switch is initializing and testing the first module,
it is possible to cause the first module or the entire switch to be reset.
Hot Swap Precautionary Procedures. To prevent the modules or switch from being reset when you must hot
swap multiple modules, follow these simple precautions:
■Do not install/remove any modules from the switch while the switch Self Test LED is lit.
■Before removing or installing any modules, make sure that all network cables are disconnected from
the module.
See the “Installing the Modules” section of the ProCurve Switch vl Modules Installation Guide, for more
information.

Software Updates Are Free!
ProCurve Networking provides free software updates on the ProCurve Web site for your Series 4200vl
Switch. To access the software updates, go to the ProCurve Web site at www.procurve.com, then click
on Software updates to go to the “ProCurve Networking software updates” page. Under Latest software
click on Switches to go to the page that has the free download for your switch.
Register for Automatic Notification of Updates. From the “ProCurve Networking software
updates” page, you can also register yourself to automatically receive email notice of new updates
for your managed ProCurve networking products.
To determine whether you have the latest software, you can compare the software version that is
available on the web site with the version that is currently installed on your switch. Follow the
instructions below to determine the current software version in your switch.
To Determine the Current Software Version in Your Switch. For the Series 4200vl Switch, use
any of the following methods to view the current software version:
■Start a console session with the switch. In the console login screen (the first screen
displayed), the Firmware revision line under the switch name shows the software version.
■If you already have a console session going, at the prompt enter the show version command.
The resulting display lists the current software version.
■In the web browser interface, click on the Identity tab. The current software version is listed
in the Version line.
To Download New Software. Your ProCurve Series 4200vl Switches support several different
methods for downloading new operating system software. For instructions on how to download the
new software, please see appendix A, “File Transfers” in the Management and Configuration Guide
on the ProCurve Web site.

Saving the Configuration After Installing or Exchanging a Module
The following cases automatically result in a change to the running-configuration on your switch:
■If you replace a module with another module of a different type and then reboot the switch
■If you install a module in a slot that has not previously been used (including when you install
a module and apply power to the switch for the first time)
If you want to save such changes to permanent memory (startup-configuration), use the write memory
command in the switch console. This causes the switch to use the new hardware configuration for
subsequent reboots. (The switch always reboots from the startup-configuration.)
If you do not save the hardware changes to the startup-configuration, you will be prompted with the
following message the next time you use the reboot or reload commands:
Do you want to save the current configuration [y/n]?
For more information on switch memory, including the startup-config and running-config memories,
refer to the Management and Configuration Guide for your switch. See “View or Download the
Manual Set” on page 1.

Mini-GBIC Operation Notes
Revision “B” mini-GBICs only. This product requires ProCurve revision “B” or later mini-GBICs (product
number ends with the letter “B” or “C”, for example J4858B, J4859C). These switches do not support revision
“A” mini-GBICs.
Use only genuine ProCurve mini-GBICs. Non-ProCurve mini-GBICs are not supported. Use of genuine
products ensures that your network maintains optimal performance and reliability. Should you require additional
ProCurve mini-GBICs, please contact a ProCurve sales representative or an authorized reseller.
Hot Swapping mini-GBICs. The mini-GBICs that you can install in your ProCurve switch or mini-GBICModule
can be “hot swapped”—removed and installed after the module is installed in the switch and receiving power.
You should disconnect the network cables from the mini-GBICs before hot swapping them.
When you replace a mini-GBIC with another mini-GBIC of a different type and then execute the write memory
command in the switch console, the switch configures the port on the new mini-GBIC with the default mode
(speed and duplex) settings used for the new mini-GBIC type. The default mode for the mini-GBICs is Auto. Note
that the switch retains other port-specific configuration settings, such as trunking, Spanning Tree Protocol (STP),
and VLAN values that were configured for the previous mini-GBIC.
Connecting the mini-GBICs to Devices with Fixed Configurations. For some older network devices,
including some older ProCurve devices, the default for Gigabit ports is a fixed configuration, for example 1000
Mbps/Full Duplex, or is otherwise different from these default configurations for the mini-GBICs, which is Auto.
As a result, those devices may not connect properly to your mini-GBIC port; you will not get a link. Because of
these default configuration and full-duplex considerations, for best operation, you should make sure that the
devices connected to the mini-GBIC ports are also configured to Auto. At a minimum, make sure the
configurations match.
