Installation

Overview

Note Before you install the HP AdvanceStack Switch Ethernet Module into

the Switch 2000, you may want to install an optional HP

802.3-compatible transceiver in the transceiver slot in the module.
(Refer to the instructions you received with the transceiver.)

If a transceiver is installed, it replaces the first 10Base-T port as port 1,
as long as no active network is connected to the built-in RJ-45 port 1. If
the Switch 2000 detects the link beat signal on the built-in RJ-45 port 1, it
automatically selects that connector to use for port 1.

You can install an Ethernet Module into the Switch 2000 in any one of the six
module slots, as follows:

1. Insert the Ethernet Module in a Switch 2000 slot (page 2).

2. Customize the configuration for the module ports (unless the default

port configuration is satisfactory for your network application - see
page 8).

3. Reboot the switch (page 9).
Other, optional proce dures include:

Hot-Swapping one module for another; that is, replacing one module
with another without turning off power to the switch (page 10)

Using the hot-swap process to install a transceiver into a module
that has already been installed in the switch (page 12)

Installation

Caution Static electricity can severely damage the sensitive electronic

components on the HP AdvanceStack Switch Ethernet Module. When
handling and installing the module in your switch, follow these
procedures to avoid damage from static electricity:

Handle the module by its edges and avoid touching the components
and the circuitry on the board.

Equalize any static charge difference between your body and the

switch by wearing a wrist strap and attaching it to the switch’s metal
body, or by continually touching the switch’s metal body while you
are installing the module.

For proper cooling and reduction of electromagnetic emissions, ensure that
a slot cover (provided with your Switch 2000) is installed on any unused port
or transceiver slot.

Installing a Module in an Unused Slot

This procedure assumes that you have either already installed an optional
transceiver in the module or do not plan to install a transceiver at this time.
(The module operates properly with or without a transceiver installed.)

1. Slide out the blank LED label strip from the label slot corresponding

to the physical slot in which you will install the module. The LED
label strips have a small loop on the left end. Use your fingernail or a
small implement to catch the loop and slide the label to the left and
out of the label slot. Then insert the LED label strip you received
with the Ethernet Module. For example, if you are going to install the
module in slot ‘‘A’’, you would replace the blank LED label strip in
label slot ‘‘A’’ with the new LED label strip for the Ethernet Module.
(Refer to Figure 1, on the next page.)

Save the blank LED label strip in case you ever want to remove the
module and its LED label strip.

2. Using a Torx T-10 or slotted screw driver, unscrew the screws in the

cover plate over the slot you want to use, and remove the cover.
Store the cover plate with its screws for possible future use. For
example, to install a module in slot A, see Figure 1.

3. Holding the module by its edges—taking care not to touch the metal

connectors—position the module in front of an open slot on the
switch by aligning the edges of the module with the small grooves
near the bottom of the module slot, as shown in the next illustration.

4. Make sure the extractor handles on each side of the module are in

the open position (rotated away from the face plate), then push the
module into the slot until you feel the extractor handles contact the
switch chassis. (The handles will move slightly upwards when they
contact the chassis.)

(for the slot in which

you are installing the

module)

1 FLASHING RAPIDLY if the module is not properly seated
2 ON for less than 1 second after the module has been

properly seated
3 OFF during normal switching operation
4 Flashing slowly if there is a self-test failure.

Check the switch event log through the console interface

for more information.
Note: If the Fault LED for the module slot continues flashing

rapidly, the module may not be completely seated in the slot.
Ensure that the handles on the module are fully in the

“closed” position and the screws in the handles are
tightened.

If the module slot Fault LED continues flashing, unscrew the
screws, open the handles, remove the module, and re-install
it. If the Fault LED continues flashing, remove the module
and contact your HP-authorized LAN dealer or HP
networking support representative.

If a module is not installed properly, and the module slot
Fault LED continues rapid flashing, normal switch operation
halts until the module is removed or properly installed (the
other modules in the switch do continue to forward packets
normally).

Self-test

(for the Switch 2000)

1 ON for up to 40 seconds after the module has

been properly seated
2 OFF during normal switching operation
3 FLASHING simultaneously with slot Fault LED if the slot

has failed self-test. Check the event log by selecting "Event

Log" from the switch’s console in the Main Menu.

Installation

6. Tighten the captured screw in each handle by using a flat-blade or
Torx-10 screwdriver. Be careful not to overtighten the screws.

Tighten These Two Screws

Figure 5. Securing the Module in the Slot

7. Connect the appropriate network cables to the module’s 10Base-T
ports (and to the optional transceiver, if installed).

Figure 6. Connecting a Cable

Note Use either the built-in RJ-45 connector or a transceiver for port 1—both

will not work simultaneously. The active port 1 connector is
automatically selected based on the following conditions:

If a cable carrying a link beat signal is connected to the first built-in
RJ-45 port on the module, then that port is the active port 1,
regardless of whether there is a transceiver installed.

If no link beat is detected on the first built-in RJ-45 port on the
module, then a transceiver, if ins talle d, become s the active port 1.

6

Installation

Note MDI-X Operation: The four 10Base-T ports built into the module are

designed for MDI-X operation (that is, for connecting end nodes to the
switch). Thus, if you connect any of these ports to an MDI-X port on

another device, use a ‘‘crossover’’ cable. But if the connection is to an
MDI port, use a ‘‘straight-through’’ cable.

MDI Operation: An optional twisted-pair transceiver in the transceiver
slot operates in MDI mode (that is, for connecting hubs or other
switches to the Switch 2000). In this case, use a ‘‘straight-through’’ cable
to connect the transceiver to an MDI-X port on another device, or a
‘‘cross-over cable’’ to connect the transceiver to another transceiver or
other MDI port on another device. See the Connectivity Quick
Reference that is included with your module for more information on
connecting the module to network devices.

For more on straight-through and crossover cables, see appendix A,
‘‘Cables and Connectors’’, in the HP AdvanceStack Switch 2000
Installation Guide that is shipped with the Switch 2000.

8. Check the port LEDs for the newly-installed module to ensure that
the port(s) connected in the preceding step are up. (If you have not
already done so, install the LED label strip as described in step 1.)
The “port-enabled’’ LED (1, 2, 3, 4) will be lit for each port that is up.
The transmit (Tx) and/or receive (Rx) LEDs for each port that is
transmitting and/or receiving packets will flash when traffic is
detected on the port.

9. Customize the port configuration, if necessary. (See “Customizing the
Port Configuration”, below.)

10. Reboot the switch, since this is a new module being installed. (See
“Rebooting the Switch” on page 9 for more information on when the
switch must be rebooted.)

Customizing the Port Configuration

If the slot in which you installed the Switch Ethernet Module was empty the
last time the switch was either rebooted or reset (or the power to the switch
was cycled), then the module will use preconfigured default parameter
values that will work for most networks.

The default 10Base-T port configuration is:

Enabled: Yes
Mode: Half Duplex

(Full Duplex can be set on any of the built-in RJ-45 ports, but not a
transceiver that is installed and used as port 1.)

T runk (port trunking): None
Broadcast Limit: 0

If necessary, configure the port(s) in the module by using the switch console
interface. (See the Console User’s Guide—HP part number
5964-4644—shipped with the Switch 2000, and the online Help provided in
the console interface itself.)

If the default port configuration, shown above, is correct for your network,
then skip this process.

Installation

Rebooting the Switch

You can reboot the switch by using the Reboot Switch command in the
console Main menu, or by pressing the recessed Reset button located to the
right of the Power LED.

Reset Button

Figure 8. Location of the Reset Button

Generally, you only need to reboot the switch when it needs to recognize a
change in its hardware or software (console) configuration. Some
circumstances under which you will need to reboot the switch are:

Adding new modules or moving modules to unused slots (page 2)
Installing a module in a slot that was previously occupied by a

different type of module (for example, installing a 100VG module in

a slot that was previously used for an Ethernet module—page 10)
Changing certain switch configuration parameters through the

console interface—in this case, the console provides messages
indicating when the switch must be rebooted for the configuration
change to be activated

You do not need to reboot the switch when:

Replacing a module with the same type of module, or moving a
module to a slot that was previously occupied by the same type of
module (page 10)

Adding or changing a transceiver in the switch module—in this case,
you must remove the module from the switch, and when it is
reinstalled, the switch recognizes the transceiver change (page 12)

Installation

Removing or Replacing a Module

Use this section to do either of the following:

Replace one module with another

Remove a module without replacing it

Loosen These Two Screws

Figure 9. Removing the Module from the Slot

1. Remove any network cables from the ports on the module.

2. Loosen the screws in the extractor handles of the module you want
to remove from the switch. (Refer to figure 5 on page 6.)

3. Simultaneously pull both extractor handles toward you until the
module releases from the slot and the Fault and status LEDs for that
slot are off.

Note During removal (or installation) the module and switch connectors will

momentarily be only partially connected. The fault LED for the slot
flashes rapidly to indicate this state, and normal switch operation is
temporarily suspended until the module connector is completely
separated from the switch connector. The other switch modules do
continue to forward packets, though.

4. Slide the module out of the slot.

10

Installation

5. Do one of the following:

• If you will be installing another module in the slot, go to ‘‘Install-

ing a Module in an Unused Slot’’ on page 2 and begin with step 3.

Make sure that you install the proper LED strip for the new
module you are installing, as described in step 1 on page 2. If

you do not install the correct LED strip for the module you have
installed, the LED display will be incorrect for that module.

• If you will not install another module in the slot (that is, leave it

empty), then re-attach a slot cover plate over the empty slot open­ing, and replace the LED strip for that slot with a blank LED strip.

6. If you are removing a module, or replacing a module with a different
type (for example, replacing an Ethernet module with a 100VG
module), then reboot the switch as described under “Rebooting the
Switch” on page 9.

Caution For proper cooling and reduction of electromagnetic emissions, ensure

that a slot cover (provided with your Switch 2000) is installed on any
unused port or transceiver slot.

11

Installation

Adding, Replacing, or Removing a Transceiver

Caution When adding, removing, or replacing a transceiver from a module,

always remove the module from the Switch 2000 first. Otherwise, you
might interrupt proper switch operation and/or damage the module or
transceiver circuitry.

For proper cooling and for reduction of electromagnetic emissions,
ensure that a slot cover (provided with your Switch 2000) is installed on
any unused port or transceiver slot.

1. Disconnect any network cables attached to the module for which
you will add, replace, or remove a transceiver.

2. Remove the module from the Switch 2000.
a. Loosen the screws in the extractor handles of the module.

b. Simultaneously pull both extractor handles toward you until the

module releases from the slot and the Fault and status LEDs for
that slot are off.

c. Slide the module out of the slot.

12

3. Do one of the following:

• If you are adding a transceiver: Loosen the captured screws

on the cover plate over the transceiver slot until they disengage
from the module, then remove the cover plate and store it for pos­sible future use.

• If you are removing a previously installed transceiver:

1) Use a flat-bladed or Torx T-10 screwdriver to loosen the
spring-loaded retaining screws on the transceiver bulkhead.

2) Slide the transceiver out of the module and place it in an antis­tatic container for protection from electrostatic discharge
(ESD).

4. Do one of the following:

• If you are adding a new transceiver or replacing one trans­ceiver with another:

Installation

1) Use the instructions provided with the transceiver to install it

in the module.

2) Re-Install the module in the Switch 2000 using the instructions

under ‘‘Ins talling a Module in an Unused Slot’’ on page 2 and
begin with step 3.

• If you are removing a transceiver without replacing it with
another transceiver:

1) Use a flat-bladed or Torx T-10 screwdriver to install an HP

10Base-T transceiver cover plate over the transceiver slot in
the module.

2) Re-Install the module in the Switch 2000 using the instructions

under ‘‘Ins talling a Module in an Unused Slot’’ on page 2 and
