Module Hot Plug/Swap Operation Notes
The Series 3400cl Switches do not support hot plugging or hot swapping of the switch cl modules. If you install
or remove modules after the switch has been powered on, a switch reset will occur. Installing or removing
modules should only be done during scheduled downtime.
However, hot swapping of the tranceivers is supported. You can install or remove transceivers with the switch
powered on.
For more information see the ProCurve Switch cl Modules Installation Guide.
Fiber Optic Transceiver Operating Temperature Variance
The fiber optic transceivers are rated at a lower operating temperature (0°C to 40° C (32°F to 104° F)), than
the 6400cl/3400cl switches or the cl modules (0°C to 55° C (32° F to 131°F)). Therefore when either
transceiver is installed in a cl module or in a 6410cl Switch it lowers the temperature rating of the
module and the switch the module is installed in to equal the rating of the transceiver.

Software Updates Are Free!
ProCurve Networking provides free software updates on the ProCurve Web site for your
Series 3400cl switch. To access the software updates, go to the ProCurve Web site at
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. You can receive email notices of new
software updates by registering your ProCurve product on the ProCurve Web portal. To
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 on your switch.
To Determine the Current Software Version in Your Switch. FortheSeries3400clswitches, useanyofthe
following methods to view the software version:
■
■
■
Start a console session with the switch. In the console login screen (the first screen displayed), the
Software 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 as the
revision number in the Version line.
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 current new hardware configuration for subsequent
reboots. (The switch always reboots from the startup-configuration.)
If you do not save 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] ?

Mini-GBIC Operation Notes
Hot Swapping mini-GBICs.
The Gigabit-SX, Gigabit-LX, and Gigabit-LH mini-GBICs that you can install in your ProCurve Switch can be “hot
swapped”—removed and installed after the switch is 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 new mini-GBIC type. The default mode for the Gigabit-SX, Gigabit-LX, and
Gigabit-LH 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 the Gigabit-SX, Gigabit-
LX, and Gigabit-LH 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.
