Features
Figure 3. Example: ProCurve Switch 1-port 10 Gig-X2 vl Module
The ProCurve Switch vl Modules have the following features:
■auto-enabled ports—the ports are all configured to be ready for network
operation as soon as a viable network cable is connected
■auto-configuration—a default configuration is applied to the module
when the switch is powered on and the module passes self test; this default
configuration works well for most network installations
■LEDs that provide information for each port on the link status, network
activity, connection bandwidth (speed), communication mode (half or full
duplex), and presence of specific network error packets on the port
■“hot swap modules” operation—you can add a module or replace a
module without having to shut down the switch (changing the module
type in a given slot does require a switch reset)
■“hot swap mini-GBICs” operation—you can add, replace, or change the
type of any of the mini-GBICs that you use in any of the vl Modules that
use mini-GBICs, without having to first remove the module, and without
having to shut down the switch (you must remove the network cable
before hot-swapping a mini-GBIC)
■“hot swap X2 transceiver” operation—you can add, replace, or change the
type of any of the X2 transceivers that you use in the 10-GbE vl Module,
without having to first remove the module, and without having to shut
down the switch (you must remove the network cable before hot-swap-
ping a transceiver)

Installing the Modules
Overview
You can install any of the vl modules into any of the ProCurve vl switches. The
modules can be installed into the switch either with the switch powered on
or off. The following procedures assume the switch is powered on.
1. Install the modules in a switch slot (see page 7).
If you have installed any modules into slots that were previously occupied
by a different type module, you need to reset the switch (see page 20).
2. If you are using the mini-GBIC vl Module, or the Gig-T/SFP vl Module,
install the mini-GBICs in the module. You can install the mini-GBICs
before or after installing that module into the switch (see page 9).

6
ProCurve Switch vl Modules
Installing the Modules
Note The mini-GBICs can be “hot swapped”. That is, they can be installed or
removed after the mini-GBIC vl Module, or the Gig-T/SFP vl Module, is
installed in the switch and the module is receiving power. The network cable
must be removed from the mini-GBIC before installing or removing a mini-
GBIC. For more information, see page 9.
3. Verify the modules are installed correctly (see page 12).
4. Connect the network cabling (see page 13).
5. Verify the network connections are working properly (see page 17).
6. Optionally, customize the port configuration for each module unless the
default port configuration is satisfactory for your network application -
(see page 18).
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. For more information, see page 19.
To prevent the modules or switch from being reset when you must hot swap
multiple modules, follow these 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.

Installing the Modules
Installing the Module in an Unused Slot
Installation Procedures:
1. Use a Torx T-10 or flat-bladed screwdriver to unscrew the screws in the
cover plate over the slot you want to use, and remove the cover. Store the
cover plate for possible future use.
2. Hold the module by its bulkhead—taking care not to touch the metal
connectors or components on the board.
3. As shown in the illustrations on the next page, insert the module into the
slot guides and slide it into the slot until it stops. Then press near the two
screws on the module bulkhead to seat the module connector into the
switch backplane. The module bulkhead should be in contact with or very
close to contact with the front face of the switch.
4. Screw in the two retaining screws to secure the module in place. The
screws should be tightened until they are secure, but not overtightened.
Installation Precautions:
■Static electricity can severely damage the electronic components on the modules. When
handling and installing the modules in your switch, follow these procedures to avoid damage
from static electricity:
• Handle the module by its bulkhead or edges and avoid touching the components and the
circuitry on the board.
• When installing the module, equalize any static charge difference between your body and
the switch by wearing a grounding wrist strap and attaching it to the switch’s metal body,
or by frequently touching the switch’s metal body.
■The ProCurve Switch vl Modules have “low-force”, high-performance connectors. High inser-
tion forces are not necessary to install the modules, and should not be used.
■Ensure you fully insert the modules.That is, press the module into the slot until the bulkhead
on the module is contacting or is very close to contacting the front face of the switch chassis.
■Once the module is fully inserted, make sure that you screw in the two retaining screws to
secure the module in place.
■For safe operation, proper switch cooling, and reduction of electromagnetic emissions, ensure
that a slot cover is installed on any unused module slot. For safety, no more than one slot at a
time should be uncovered to install a module, when the switch is powered on.

Installing or Removing the Mini-GBICs
Note Hot swapping mini-GBICs is supported. You can install or remove a mini-GBIC
with the switch powered on, a reset will not occur.
You can install or remove the mini-GBIC from the mini-GBIC vl Module, or the
Gig-T/SFP vl Module, without having to power off the switch. Use only
ProCurve mini-GBICs with the letter “B” (or greater) at the end of the product
number (for example, J4858B or J4860C).
WARNING The ProCurve fiber optic mini-GBICs are Class 1 laser devices. Avoid
direct eye exposure to the beam coming from the transmit port.
Then tighten the retaining screws
onthemoduleuntiltheyare secure,
but do not overtighten them.
The module is fully inserted when
the module bulkhead is contacting,
or very close to contacting
the face of the switch.

Installing the Modules
Caution Use only supported genuine ProCurve mini-GBICs with your switch. Non-
ProCurve mini-GBICs are not supported, and their use may result in product
malfunction. Should you require additional ProCurve mini-GBICs, contact
your ProCurve Networking Sales and Service Office or authorized dealer.
Installing the mini-GBICs:
Hold the mini-GBIC by its sides and gently insert it into any of the slots in the
module until the mini-GBIC clicks into place.
Figure 6. Installing/removing a mini-GBIC
Removing the mini-GBICs:
The network cable should be disconnected from the mini-GBIC before
removing it from the module.
Depending on when you purchased your ProCurve mini-GBICs, it may have
either of three different release mechanisms: a metal latch, a wire bail, or a
plastic collar around the mini-GBIC.
To remove the mini-GBICs that have the plastic collar, push inthe plastic collar
toward the switch until you see the mini-GBIC release from the switch (you
can see it move outward slightly), and then pull the mini-GBIC from the slot.
To remove the mini-GBICs that have the wire bail or metal latch, lower the
bail or latch until it is approximately horizontal, and then using the bail or
latch, pull the mini-GBIC from the slot.

Install or Remove a Transceiver
Note Hot swapping transceivers is supported. You can install or remove a trans-
ceiver with the switch powered on, a reset will not occur.
a. Slide the transceiver in until it stops.
Figure 7. Installing an X2 transceiver
b. Push firmly until the gasket seats against the bulkhead. The transceiver
should “click” into place.
Figure 8. X2 transceiver fully installed
Note If the switch is powered on when the transceiver is installed, the Link and
Mode LEDs will come on for approximately two seconds and then go off. This
is confirmation the transceiver is completely seated.
c. If your transceiver has a bail, move the bail up, if not your transceiver is
now completely installed.
Refer to page 30 for more transceiver details.
To remove the transceiver:
If your transceiver has a bail, lower the bail until it is approximately horizontal,
and then using the bail, pull the transceiver from the slot. If your transceiver
does not have a bail, pull the transceiver straight out.

Verifying the Module is Installed Correctly
Observe the Module Status LED for the slot in which the module is being
installed, and the Self Test and Fault LEDs on the switch to verify the module
is installed properly.
Figure 9. Checking LEDs for correct installation
When the module is installed properly and the switch is powered on, or the
module is installed when the switch already has power, the module undergoes
a self test that takes a few seconds. You can use the LEDs to determine that
the module is installed properly and has passed the self test, as described in
the “LED Behavior” table below.

LED Display for a Properly Installed Module
Module Status (for the slot in which you are installing the module) The LED goes
ON as soon as the module is installed and the switch is powered on,
and stays ON steadily.
Self Test ON briefly while the module is being tested, then OFF.
Note: If the switch was powered off while the module was installed,
when the switch is powered on, the Self Test LED will stay ON for
the duration of the whole switch self test.
Fault OFF
Link and Mode (on
the modules) For a module that is installed when the switch is already powered on (hot swap), all the Link and Mode LEDs on the module go ON for
approximately 3 to 10 seconds, then OFF for 5 to 10 seconds
depending on the module.
If the module is already installed when the switch is powered on or
reset, the process described above occurs approximately 30
seconds after the power on or reset, during which time the switch
is being tested.

Installing the Modules
Connecting the Network Cables
Note Automatic Cable Sensing on Twisted-Pair Ports:
When the ports for the 10/100-TX and the Gig-T vl Modules are in their default
configuration, Auto, both modules automatically negotiate whether the ports
operate as MDI or MDI-X, depending on the cable type and the connected
device’s operation. As a result, you can use either straight-through or
crossover twisted-pair cables for all network connections to these modules.
On the 10/100-TX vl Modules, this feature is identified as HP Auto MDI-X; on
the Gig-T vl Module, it is identified as IEEE Auto MDI/MDI-X and it is part
of the IEEE 802.3ab standard. Both features operate the same.
Operation of this feature depends on the port configurations being kept at
Auto. If the configuration is changed to one of the available fixed options (for
example, 100-Full Duplex), the port operates as an MDI-X port. In that case,
to connect the module to another switch or hub, use a crossover cable; to
connect to an end node, use a straight-through cable.

Notes:
• The RJ-45 ports on this module have the HP Auto MDI-X feature. In the default configuration, Auto, either a straight-
through or crossover cable can be used to connect the port to any other 1000Base-T, 100Base-TX or 10Base-T device.
See the Note on page 13.
• Since the 10Base-T operation is through the 10/100Base-TX or 10/100/1000-T ports, if you ever want to upgrade the
ports to 100Base-TX, it would be best to cable the ports initially with category 5 cable or better.
