HP Procurve SwitchXL Modules
Features
Features
Example: The HP Procurve 24-Port 10/100-TX XL Module
The HP Procurve Switch XL Moduleshave the following features:
■ auto-enabled ports—the ports are all configured to be ready for network
operation as soon as a viable networkcable 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 the mini-GBIC XL Module,
without having to first remove the module, and without having to shut
down the switch

Installing the Modules
Installing the Modules
Overview
You can install any of the modules into any of the HP Procurve XL Switches
that have a compatible module slot. As of this printing, those are the
HP Procurve Series5300XL Switches:
■5308XL (p/n J4819A)
■5372XL (p/n J4848A)
■5348XL (p/n J4849A)
■5304XL (p/n J4850A)
You can install the modules into the switch either with the switch powered on
or off. The following procedures assume the switch is powered on.
1. Install the modules ina switch slot (see page 5).
If you have installed any modules intoslots that were previously occupied
by a different type module, you need to now reset the switch (seepage 15).
2. If you are using the mini-GBIC XL 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 7).
Not e The mini-GBICs can be “hotswapped”. That is, they can be installed or
removed after the mini-GBIC XL Module is installed in the switch and the
module is receiving power. For moreinformation, see page 7.
3. Verify that themodules are installed correctly (see page 8).
4. Connect the network cabling (seepage 9).
5. Verify that the network connections are working properly (see page 12).
6. Optionally, customize the configuration for the modules’ ports (unless the
defaultport configuration is satisfactory for your network application -
see page 13).
Not e If necessary, you can “hot-swap” one module for another; that is, replace one
module with another while the switch is still powered on, without interrupting
the operation of the rest of the switch ports. For more information, see page 14.

Installing the Modules
Installing the Module in an Unused Slot
InstallationPrecautions:
■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 byits bulkhead or edges and avoid touching the components and the
circuitry on the board.
• When installing the module, equalize anystatic charge difference between your body and
theswitch by wearing a grounding wrist strap and attaching itto the switch’s metal body,
or by frequently touching the switch’s metal body.
■The HPProcurve Switch XL Modules have “low-force”, high-performance connectors.
High insertion forces are not necessary to installthe modules, and should not be
used.
■Make sure that 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 should
be uncovered at a time when the switch is powered on.
InstallationProcedures:
1. Use a Torx T-10 or flat-bladed screwdriver to unscrew the screws inthe
cover plate over the slot you want to use, and remove the cover. Store the
cover platefor possiblefuture 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 back face of the switch.
Note: The HP Procurve Switch XL Modules have “low-force”, high-
performance connectors. Highinsertion forces are not necessary
to install the modules and should not be used.

Installing the Modules
Installing or Removing the mini-GBICs
You can install or remove the mini-GBIC from the mini-GBIC XL Module
without having to power off the switch. Use only HP Procurve mini-GBICs.
Caution The HP Procurve mini-GBICs are Class 1 laser devices. Avoid direct eye
exposure to the beam coming from the transmit port.
Installing the mini-GBICs:
Hold the mini-GBICby its sides and gently insert it into any of the slots in the
module until the mini-GBIC clicks into place.
Removingthemini-GBICs:
You should disconnect the network cable from the mini-GBICbefore removing
it from the module.
Dependingon when you purchased your HP Procurve mini-GBICs, it may have
either of three different release mechanisms: a plastic tab on the bottom of
the mini-GBIC, a wire bail, ora plastic collar around the mini-GBIC.
To remove the mini-GBICsthat have the plastictab or plastic collar, push in
theplastic tab orcollar toward theswitch until you see the mini-GBIC release
from the switch (you can see it move outward slightly), and then pull it from
theslot.
To remove the mini-GBICs that have the wire bail, lower the bail until it is
approximately horizontal, and then using the bail, pull the mini-GBIC from the
slot.

Installing the Modules
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 that the
module is installedproperly.
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 Behavior
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 staysON 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 For a module that is installed when the switch is already powered
the modules) on (hotswap), all the Link and Mode LEDs on the module go ON for
approximately 3 to10 seconds, then OFF for 5 to 10 seconds
depending on the module. Then, the Self Test LEDon the switch goes
OFF.
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 the switch is
being tested.

Installing the Modules
Not e Automatic CableSensing onTwisted-Pair Ports:
When the ports forthe 10/100-TX XLModule andthe 100/1000-T XL Module
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 cable for all network connections to
these modules.
On the 10/100-TX XL Module, this feature is identified as HP Auto-MDIX; on
the 100/1000-T XL Module, it is identified as Auto MDI/MDI-X and it is part
of the IEEE 802.3ab standard. Both features operate the same.
Operation of these feature depends on the port configurationsbeing kept at
Auto. If the configuration is changed toone of the available fixed options
though (forexample, 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; toconnect to an end node, use a straight-through cable.

HP Procurve SwitchXL Modules
Installing the Modules
Verifying the Network Connections Are Working
Check the portLEDs for the newly-installed module to ensure that the port(s)
connected in the preceding step are operating correctly. Each port on the
switch modules has Linkand Mode LEDs near it as shown in the next
illustration.
Example Link and Mode LEDs
■ The Link LED will belit for each port that is connected properly to an
active network device.
If the Link LED does not go on when an active network cable is connected
to the port, there may be something wrong with the cable, the cable
connectors, or the device at the other end of the cable. Seethe trouble-
shooting information on page 16.
■If the switch Mode is set to display activity (the

mode indicator LED
is lit), then the Mode LED for each port that is transmitting and/or
receiving packets will flicker when traffic is detected on the port.
■If the Mode is set to display full duplex (the

mode indicator LED is
lit), then the Mode LED will be lit for each port that is operating in full
duplex.
■If the Mode is set to display maximum link speed operation (the

mode
indicator LED is lit), then the ModeLED will be lit for each port that is
operating at its maximum possible link speed. For gigabit-capable ports,
that speed would be 1000 Mbps (Gigabit); for 10/100 ports, that speed
would be 100 Mbps.
■If the Mode is set to display packet errors on the port (the �mode
indicator LED islit), then the Mode LED will flash briefly for each packet
that hasany of six errors, including CRC errors and late collisions.

Installing the Modules
Customizing the PortConfiguration
If the slot in which you installed the module was empty the last time the switch
was either rebooted or reset (orthe power to the switch was cycled), then the
module will use preconfigured default parameter values that will work for
most networks.
The default port configurations for connection parameters are:
■Ports Enabled:Yes
■Mode:
• 10/100-TX XL Module: Auto —The port auto negotiates speed (10
or 100Mbps), communication mode (half or full duplex), and MDI or
MDI-X portoperation. Note:if you configure the port to one ofthe
fixed 100 Mbps modes, the port will then operate only as an MDI-X
port.
• 100/1000-T XL Module: Auto — The port auto negotiates speed
(1000 or 100 Mbps), communication mode (half or full duplex), and
MDI or MDI-X port operation. Note:if you configure the port to one
of the fixed 100 Mbps modes, the port will then operate only asan
MDI-X port.
• Gigabit-SX, Gigabit-LX, and Gigabit-LH ports inmini-GBIC XL
Module: Auto — The port always operates at 1000 Mbps and full
duplex. The setting is Auto for best link establishment with other
devices.
• 100-FX MTRJ XL Modules: 100FDX — The port operates at100 Mbps
and full-duplex.
■Flow Control: Disabled
■ Advanced features— Spanning Tree, Trunking, Meshing, VLANs, IGMP,
LACP, Routing,Class of Service,Security, etc.: all Disabled
If necessary, configure the port(s) in the module by using the switch console
or the web browser interface. For moreinformation,see the Management and
Configuration Guide shipped on the documentationCD that came with the
switch, and the online Help provided in the console and web browser inter-
faces.
If the default port configuration listed above is acceptable for your network,
then skip this process.

Replacing or Removing a Module
Replacing or Removing a Module
Follow these procedures to replace one module with another, or to remove a
module without replacing it:
1. Remove any network cables from the ports on the module.
2. On the module youwant to remove fromthe switch, unscrew the retaining
screws enough to disconnect them from the threaded holes in the switch.
3. Grab the screws and pull the module out fromthe slot. It may help to brace
your hands against the face of the switch and “lever” the module out from
the switch slot.
4. Do one of the following:
• If you will beinstalling another module in the slot, go to “Installing
the Module in an UnusedSlot” on page 5 and begin with step 2.
• If you will not install another module in the slot (that is, leave it
empty), thenre-install a slot cover plate over the empty slot opening.
Caution For proper cooling and reduction of electromagnetic emissions, ensure that
aslot cover is installed onany unused slot.
5. Reset the switch, as described under “Resetting the Switch” on page 15,
if you are exchanging one type of module with a different type of module
in the same slot (for example, replacing a 10/100-TX XL Module with a
100/1000-T XL Module).
If you are replacing amodule with another one of the same type in the
same slot, it is not necessaryto reset the switch. The currentconfiguration
for ports in that slot will apply to the newmodule.
