Introduction
The Alcatel OmniStack® 6148 is perfect for moving workgroups from conventional
10 Mbps Ethernet to multiple-segment 100 Mbps Fast Ethernet, and for
consolidating your network equipment into a single, clean, efficient, and super-fast
switch stack. This switch system delivers dedicated 100 Mbps links to each attached
LAN segment (independent collision domain) or to any PC attached directly to the
stack – all with conventional cabling and adapters. It completely eliminates the
bottlenecks of shared 10 M bps Ethernet networks by provid ing a w i de bandwidth of
up to 13.6 Gbps per switch, and a stack bac kplane that can operate at up to
9.6 Gbps. This makes it ideal for increasing the throughput of in terconnected
Ethernet and Fast Ethernet hubs or server farms.
This switch includes three slots on the rear panel for various modules:
• The upper slot is fo r an SNMP /RMON Manag ement Mod ule. The stack s upports one
master and one backup management agent.
• The lower right slot is for optional media expansion modules, including a dual-port
100 Mbps fiber optic modul e t ha t ca n be connected to a remote site up t o
2 kilometers (1.24 miles) away, or a single-port Gigabit module that can be used to
uplink to a collapsed Gigabi t back bone or for a high-speed server connection.
• The lower left slot is for either an optional media expansion module or Stacking
Module. (Up to three sw itch uni t s can be stacked together usi ng Stacking
Modules.)
When the Management M odule is installed, this system can pro vi de a w id e ar ra y of
advanced features:
• Master agent module m anages entire stack in-band or o ut -o f-band
• Backup agent module pro vides fault tolerance
• A fault-tolerant closed -loop stack architecture is sup por t ed w i t h a Redundant
Stacking Module
• Supports Telnet, SNMP/RMON and Web-based inter f ace
• Four-group RMON (includi n g St at istic s, His tory , Alar m s a nd Events)
• Spanning Tree Algorithm for r edundant paths between sw itc hes
• VLAN support for up to 256 gr oups, port-based or with 802.1Q VLAN tagging
• GVRP for automatic VLAN learning*
• IGMP multicast filtering
• Quality of Service support s tw o le vels of priority with Weighted Fair Q ueueing
• Configurable broadc ast st or m control
• Port mirroring (for r eal-time de bugging without affecting the tar get port)
• Port trunking (up to 5 trunks per switch or 12 trunks for the entire stack, each trunk

Description of Hardware
The base unit contains 48 10BASE-T/100BAS E- TX por ts, plus three slots on the
rear panel for various modules. A Management Module can be installed in the upper
slot on the rear panel (see page 3). Th e low er -left sl ot can be used for an optional
media expansion module or Stacking Module, while the l ower-rig ht slot can be used
for a media expansion module. Note that the media expansion mo dul e s in cl ud e a
Fast Ethernet fiber optic module with two 100BASE-FX (SC type) ports or a one port
Gigabit 1000BASE-SX (SC type), 1000BASE- LX (SC type), 1000BASE-T, or GBIC
uplink module.
All RJ-45 ports on the base unit ope ra te at 10 or 100 Mbps, and support
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and flow control.
The 1000BASE-SX and 1000BASE-LX ports are fixed at 1000 Mbps but
auto-negotiate duplex mode. Th e 10 00BASE-T auto-negotiates duplex mo de and
auto-negotiates speed to 10 /100/1000 Mbps. The 100BASE-FX module is fixed at
the 100 Mbps, full duplex. All med ia types can auto-negotiate flow control.
Note that when using auto -n egotiation, the speed, transm ission mode and flow
control can be automatically set if this feature is also supp or te d by the attached
device. Otherwise, these items can be manually conf i gured for any connection.
The base unit also includes a display panel for key system and port indications that
simplify installation and net work troubleshooting.

Mounting the Switch
This switch can be placed directly on your desktop, or mounted in a rack.
Before you start installing the switch , make sure you can provide the right oper at i ng
environment, including power requirements, sufficient physical space, and proximity
to other network devices t hat are to be connected. Verify the following installat io n
requirements:
• Power requirements: 100 to 240 VAC (± 10%) at 50 to 60 Hz (± 3 Hz). The switch’s
power supply automat ic all y adj usts to the input voltage level.
• The switch should be located in a cool dry place, with at least 10 cm (4 in.) of space
on the sides for ventilation.
• Place the switch out of direct sunlight, and away from heat sources or areas with a
high amount of electromagnetic interference.
• If you intend to mount the switch in a rack, make sure you have all the necessary
mounting screws, brackets, bolts and nuts, and the rig ht too l s.
• Check if network cables and connectors needed for inst al l at ion are available.
Stacking Switches on a Flat Surface
The OmniStack® 6148 can be stacked
anywhere there is enough flat space, such
as on a table or desktop.
1. Stick the self-adhesive rubber foot
pads (that come with this package) on
each of th e 4 c oncav e sp ace s l ocat ed
on the bottom of the first switch.
2. Place the first switch on a firm flat sur fa ce wh er e you want to install the stack.
3. Repeat step 1 for each switch before stacking them. The switch’s rubber foot
pads cushion the switch a ga in st shock/vibrations and provide space between
each switch for vent ilation.

switch in the rack.
Installing a Management Module
One Management Module is required to manage all of the switches in the stack. One
other backup Management Module may also be installed in the stack to provide fault
tolerance. A Management Module only installs in a switch’s rear-panel upper slot, do
not try to install it in either of the two lower slots.
If you install a backup Management Module, it will automatically take over from the
master should it fail. The switch with the lowest stack unit ID will always act as the
master agent. For more informatio n on switch manag ement and the fail-over
process, see the OS-61 48 Users Guide.
Note: A Management Module may be installed in any unit in the stack, but it is
suggested that the module be installed in the switch with the stack unit ID of “1.” In
a stack with no “closed-loop” (see “Connecting Stacking Modules across Multiple
Switches” on page 5), unit ID 1 will be the switch without a connection on the
Stacking Modules “UP” port. For a closed-loop stack, unit ID 1 will be the switch
that has the Redundant Stacking Module installed.
You can install a Management M odule as described below:
1. Disconnect power to the switch (the modules are not hot - sw appable).
2. Remove the face plate on th e sw it ch’s up per slot by removing the two scr ew s
with a flat-head screwdriver.
3. Before opening the package tha t contain s th e m odule, touch the bag to the
switch casing to discharge any potential static electricity.
4. Remove the module from the anti-static shielded bag.
5. Holding the module level, gently push it all the way into the slot along the guide
rails, ensuring that it firmly en gages with the connector.
6. If you are sure the module is properly mated with the conne ctor, tighten the
retainer screws to secure th e module in the slot.
Caution: The slide-in modules are not hot-swappable. Be sure you power off the switch
before installing any of these modules.

Installing the Switch
Installing Optional Media and Stacking Modules
The two lower slots on the rear panel of th e sw it ch are provided for various op tion al
media expansion modules (10 0BASE-FX or Gigabit) or Stacking Modules. The
100BASE-FX fiber optic module can be used to connect to remote sites, and a
Gigabit module can be used as a network backbone. You can install the media
expansion modules in either of the two lower slots, but the Stacking Module must
only be installed in the lower-left slot.
Y ou can install a module as described below:
1. Disconnect power to the switch (the
modules are not hot-swappable).
2. Remove the face plate on th e
appropriate slot by remov i ng t he t wo
screws with a flat-hea d sc rewdriver.
3. Before opening the package tha t
contains the module, touch t he ba g t o
the switch casing to discharge any potential static elect r ic ity.
4. Remove the module from the anti-static shielded bag.
5. Holding the module level, gently push it all the way into the slot along the guide
rails, ensuring that it firmly en gages with the connector.
6. If you are sure the module is properly mated with the conne ctor, tighten the
retainer screws to secure th e module in the expansion slot.
Caution: The slide-in modules are not hot-swappable. Be sure you power off the switch
before installing any of these modules.
Connecting Stacking Modules across Multiple Switches
Plug one end of the stack cable (p ro vided with the
package) in the “DOWN” port of the top unit and the other
end to the “UP” port of the next unit. Repeat this step for
each unit in the stack. Form a simple chain starting at the
Down port on the top switch and ending at the Up port on
the bottom switch (stackin g up to t hr ee units).
The OS-6100-RST-KIT Redundant Stacking Module
allows you to configure a closed-loop architecture th at
provides fault-tolerant oper ation of the stack. If a switch
or stacking module fails, or if a stacking cable is
disconnected, the entire stack will reboot and will
subsequently resum e nor mal operation and
management via the redundant stacking cable (Clos ed
Loop). Also, any changes to the stack including
powering down of a unit or the insertion of a unit will
cause the stack to reboot.

Note the following points ab ou t a closed-loop stack:
• The OS-6100-RST-KIT R edundant Stacking Module must be installed in the unit
that contains the master Management Module (Unit ID = 1) . All ot her switches in
the stack can use the OS-6STK-KIT Stacking Module.
• To form a closed loop, conn ect the 1 m long stacking cable (in cluded in the
Redundant Stacking Module kit) from the Up port on the top switch to the Down port
on the bottom switch.
• To enable the closed-loop function, be sure that the button on the panel of the
Redundant Stacking Module is fully pressed in. Use the tip of a pen or other sharp
object to achieve this.
Note: Do not leave one end of a stacking cable unconnected. Be sure both ends are
properly connected, or remove the cable entirely.
Installing a GBIC Transceiver
The lower two slots on the rear panel can be
used for a single-port GBI C upl ink module.
GBIC Module
1000Base X
TXRX
This module supports 1000BASE- SX, 100 0BASE-LX and 1000BASE-LH 5 V GBIC
transceivers.
The 1000BASE-SX GBIC transceivers provide one short-wavelength (850 nm) Gigabit
port that can be used for a high-speed backbone o r s erve r connection. This port can
be connected to a site u p to 22 0 m (7 22 f t) awa y with 62 .5/125 m icron mu ltimod e fiber
cable, or up to 500 m (1641 ft) with 50/125 micron multimode fiber cable.
The 1000BASE-LX GBIC transceivers provide one long-wavelength (1300 nm)
Gigabit port that can be use d f or a high-speed backbone or server connection. T his
port can be connected to a site up to 5 km (16404 ft) aw ay with single-mode fiber
cable.
The 1000BASE-LH GBIC transceivers provide one long-wavelength (1550 nm)
Gigabit port that can be u sed for a long-haul c onnectio n to a remo te site. This port can
be connected to a site up to 70 km (43.5 miles ) aw ay with single-mode fiber cable.
Caution: Install only 5 V GBIC transceivers into the module slots.
You can install a GBIC transce iver as described below:
1. Insert the tranceiver with the SC connector facing out toward you. Note that the
transceiver is keyed so th at it ca n onl y be installed in one orientation.
2. Press in on the transceive r’s side tabs, and gently slide it into the GBIC
interface slot until it clicks into place.
Notes: 1. GBIC transceivers are hot-swappable. You do not need to power off the
switch before installing or removing a transceiver.
2. For 64-byte frames, the GBIC module is known to drop a certain percentage
of traffic.

Installing the Switch
Connecting the Switch System
The OmniStack® 6148 provides 48 RJ-45 ports on the base unit. Each of these ports
supports a connection to 10 M bps Eth er net or 100 Mbps Fast Ethernet, and
supports full or half-duplex op er at i on. The transmission speed for each port is
automatically set by the sw i t ch t o m at ch the hi ghest speed supported by the
connected device. The t ra nsmission mode can be set fo r ea ch port using
auto-negotiation (if also supported by the attached device). However, if the device
attached to any port on the switch does not support auto-negotiation, you can
manually configure the transmission mode via the console port on the rear panel, or
via an in-band connection (including Telnet, the Web agent or management
software).
Making a Connection to an RJ-45 Port
The RJ-45 ports on the switch supp or t aut om at i c M D I /MDI-X operation, so you can
use standard straight-thro ugh twisted-pair cables to connec t to an y ot he r network
device (PCs, servers, switches, routers, or hubs).
Note: If auto-negotiation is disabled for an RJ-45 port, the auto-MDI/MDI-X pin signal
configuration is also disabled.
1. Prepare the network devices you wish to network. Make sure you have installed
10BASE-T or 100BASE-TX network interfac e car ds for connecting to the
switch’s RJ-45 station ports.
2. Prepare straight-through shielded or unshielded twisted-pair cables with RJ-45
plugs at both ends. Use 100 -o hm C at egory 3, 4 or 5 cable for standard
10 Mbps Ethernet connectio ns, or 100-ohm Category 5 cable for 1 00 M bps
Fast Ethern et connections.
3. Connect one end of the ca ble to th e R J- 45 port of the network interface ca rd,
and the other end to any available RJ-45 port on the switch. All RJ- 45 por ts
support 10 Mbps and 100 Mbps Eth er net connections. When ins erting an
RJ-45 plug, be sure the tab on the plug clicks into position to ensure that it is
properly seated. Using the switch in a stand-alone configuration, you can
network up to 48 end nodes .
Caution: Do not plug a phone jack connector into any RJ-45 port. This may damage the

Therefore, when cascading devices other than this switch, please refer to the
accompanying docum entati on for cascade restrictions . However, note that because
switches break up the path for connected devices into separat e collision domains,
you should not include the
switch or connected cabling in your calculations for
cascade length involving other devices.
Connecting to a 100BASE-FX Port
100BASE-FX Module
TXTXRX RX
If you connect fiber cabl e t o th e
100BASE-FX module, be sure you use an
SC-type connector. When inserting the cable, be sure the tab on the plug clicks into
position to ensure that it is pro per l y seated. If you use an SC-to-ST co nverter, run
cable from the Rx (Tx) port on the module to the Tx (Rx) port on the target device.
Note that the fiber optic po rts oper at e only at 100 Mbps, full duplex. In this mo de,
you can run a fiber optic link up to 2 kilometers (1.24 miles).
Caution: The media expansion modules are not hot-swappable. Be sure you power off
the switch before installing any of these modules.
Note: As a general rule, the length of fiber optic cable for a single switched link should
not exceed 2 kilometers (1.24 miles). However, budget constraints must also be
considered when calculating the maximum cable length for your specific
environment.

below.
Warning:This switch uses lasers to transmit signals over fiber optic cable. The lasers are
compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.
1. Remove and keep the SC port’s rubber cover. When not connected to a fiber
cable, the rubber cove r sh ould be replaced to protect the opt ic s.
2. Check that the fiber t erminator s are clean. You can clean the cable plugs by
wiping them gently with a cl ean tissue or cotton ball moist en ed w i t h a little
ethanol. Dirty fiber terminat ors on fib er o pti c cabl es will impair the quality of the
light transmitted through the cable and lead to degraded performance on the
port.
3. Connect one end of the cable to the SC port on the switch and the other end to
the SC port on the other device. Since SC connectors are keyed, the cable can
be attached in only one orientation . W he n in serting the cable, be sure the tab
on the plug clicks into position to ensure that it is properly seated.

Powering On the Switch
1. Plug the power cord into the power socket on the rear of the switch, and the
other end into a power outle t. (If you have purchased a redund ant power
supply, plug it into the “DC INPUT” receptacle on the rear of the s w itc h. )
2. Check the LED marked Pow er on the front panel to see if it is on. The unit w ill
automatically select th e set t in g that m at ches the connected inpu t vo ltage.
Therefore, no additional adj ustments are necessary when connecting it to any
input voltage within the range m ar ked on the rear panel.
3. The switch performs a sel f-di ag nostic test upon power-on. (N ot e t hat thi s te st
takes several minutes to c om pl et e.)
Note: The unit supports a “hot remove” feature which permits you to connect or

Verifying System Operation
Verify that the stack has at least one Management Module correctly installed and
operating. The “Mgmt” LED on the switch that contains the M an agement Module
should be on, indicating th at the m odule is installed and operating corr ect l y.
Verify that the stack connections are operating correctly. Each switch in the stack
has it’s own unique unit ID (a numb er from 1 to 3) dis pl ay ed by the front-panel LCD
labeled “Switch ID.” The switch that contains the master Management Module and a
Redundant Stacking Module always has the unit ID “1.” If any switch in th e stack
displays a flashing or un stable unit ID for more than 30 seco nds, you should check
the following items:
• Reset the stack by powering off all switches and the n powering them back on.
• Be sure that all Stacking Modules are correctly installed in each switch’s lower-left
slot and the stacking cables are properly attached.
Ve r i fy that any opt ional modul es are installed corr ectly. The Mod ule 1 or Module 2
“Status” LEDs on the switch panel should be on, indi cating that the modules are
installed and operating correctly.
Verify that all attached devices have a valid connection. The switch monitors the link
status for each port. If any devic e is pr operly connected to the switc h and
transmitting a link signa l, the Li nk indicator will light up for the corresponding port. If
the Link indicator fails to light w hen you connect a device to th e sw it ch, check the
following items:

Installing the Switch
• Be sure all network cables and connectors are properly attached to the connected
device and the switch.
• See if your cable is function ing pr operly by using it for another por t an d at t ach ed
device that displays val i d indi cations when connecte d to the net w or k.
• Be sure no twisted-pair cable exceeds 100 meters (328 feet). 100 Mbps fiber cable
should be under 2 kilomet er s (1 .2 4 m i les) . Th e m aximum length for fiber op tic
Gigabit connections is listed in the table on the preceding pa ge.
Applications
This switch segments your ne two rk , sig ni fic ant ly i ncreasing both bandwidth and
throughput. Any port on the switch can be attached to a hub (a shared collision
domain) or provide a dedi cated link to a single network device (such as a
workstation or server). When a port on the switch is connected to a hub (a 10 or 100
Mbps repeater), the bandwi dth provided by that port is shared by all th e devices
connected to the attached hub. However, when a port is connected to an end n ode
or to a device that breaks up the collision domain (e.g., anot her switch, bridge or
router), the attached devic e has access to the full bandwidth provided by that port.
Bridging Functions - This switch provides fully t ra nspar ent bridging functions.
It automatically learns nod e addresses, that are subsequently used to filter and
forward all traffic based on the destination address. Wh en t ra ffic passe s between
devices attached to the sa m e shared collision domain, those packets are filtered
from the switch. But when tr affic mus t b e passed between unique segm ents (i.e .,
different ports on the switch), the high-speed switching fabric fo rwards the packets
at near zero latency.
Switching Functions - Store-and-forward switchi ng is u sed to forward traffic to
other ports. This scheme ensur es data integrity and provides a clea n data stream.
Flexible Configuration - This switch is not only designed to segment your network,
but also to provide a wide range of options in setting up network connections. It can
be used as a simple stand-alone switch; stacked up to three high; or connected with
standard repeater hubs, sw i tc hes, or other network interconnection devices in
various configuratio ns .
Media Expansion Options - You can use a Fast Ethernet fiber module to connect
to remote sites up to 2 kilome t er s (1 .2 4 m iles) away, or a Gigabit module to support
applications such as high-speed file servers, or for connecting to a collapsed Gigabit
backbone switch.

Check the power outlet by plugging in another device
that is functioning properly. Check the power cord with
another device. If these measures fail to resolve the
problem, contact your Alcatel distributor.
Verify that the switch and attached device are
powered on. Be sure the cable is plugged into both the
switch and corresponding device. Verify that the
proper cable type is used and its length does not
exceed specified limits. Check the adapter on the
attached device and cable connections for possible
defects. Replace the defective adapter or cable if
necessary.
Check that the Management Module is correctly
installed in the upper slot on the switch rear panel (at
least one Management Module is required in a switch
stack). Test the Management Module by installing it in
another switch unit. If these measures fail to resolve
the problem, contact your Alcatel distributor.
Check that the module is correctly installed in one of
the two lower slots on the switch rear panel. Test the
module by installing it in another switch unit. If these
measures fail to resolve the problem, con tac t your
Alcatel distributor.
Reset the stack by powering off each switch unit in the
stack and then powering them back on. Check all
Stacking Modules are installed correctly in the
lower-left slot on the rear panel of each switch. Check
that all stacking cables are connected correctly. If
these measures fail to resolve the problem, contact
your Alcatel distributor.
Power and Cooling Problems
If the power indicator does not turn on when the power cor d is pl ugg ed i n, you may
have a problem with the pow e r ou tlet , pow e r c ord, or internal power supply as
explained in the previou s se ct i on. H owever, if the unit powers off after running for a
while, check for loose power connections, power losses or surges at the power outlet,
and verify that the fans on the right side of the unit are unobstructed and running
prior to shutdown. If you still cannot isolate the problem, then the internal power
supply may be defecti ve. In this case, contact your Alca t el dis t ri butor for assistance.
Installation
Verify that all system components have been pr operly installed. If one or more
components appear to be m al functioning (e.g., the power co rd or network cabling),
test them in an alternate envi r onment where you are sure th at all the ot her
components are functioning properly.

Port and Cable Assignments
Port and Cable Assignments
RJ-45 Port Description
Caution: DO NOT plug a phone jack connector
into any RJ-45 port. Use only
twisted-pair cables with RJ-45
connectors that conform with FCC
standards.
For 100BASE-TX/10BASE-T connections, a twisted-pair cable must have two pairs
of wires. Each wire pair is identified by t wo di fferen t color s. For example, one wire
might be red and the other, red with white stripes. Also, an RJ-45 connector must be
attached to both ends of the cab l e.
Caution: Each wire pair must be attached to the RJ-45 connectors in a specific
orientation.
10BASE-T/100BASE-TX Pin Assignments
With 100BASE-TX/10BASE-T cable, pins 1 and 2 are used for transmitting data, and
pins 3 and 6 for r eceiving data.

Because all ports on this switch support automatic MDI/M DI -X operation, you can
use straight-through cables for all network connections to PCs or servers, or to other
switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the
cable, are connected str ai gh t through to pins 1, 2, 3 and 6 at the other end of the
cable. The table below shows the 10BASE-T/100BASE- TX M DI and MDI-X por t
pinouts.

OmniStack® 6148
1000BASE-T Pin Assignments
The table below shows the 1000BASE-T MDI and MDI-X port pinouts. These ports
require that all four pairs of wires be connected. Note that for 1000BASE-T
operation, all four pairs of wires ar e used for both transmit and rece ive.
Use 100-ohm Categor y 5 or 5e unshielded twisted-pair (UTP) or sh ie lded
twisted-pair (STP) cable for 1000BASE-T connections. Also be sure that the length
of any twisted-pair connection does not exceed 100 meter s (3 28 feet).

1000BASE-T Cable Requirements
All Category 5 UTP cables that are used for 100 BASE-TX connections should also
work for 1000BASE-T, providing that all four wire pairs are connected. However, it is
recommended tha t for all cr itical connections, or any ne w cable installations,
Category 5e (enhance d C at eg ory 5) cable should be used. The Cat egory 5e
specification include s te st param eters that are only recommendations for Category
5. Therefore, the first step in pre paring existing Category 5 cabling f or run ni ng
1000BASE-T is a simple test of the cable installation to be sure that it complies with
the IEEE 802.3ab standards.
Cable Testing for Existing Category 5 Cable
Installed Category 5 cabling must pass tests for Attenuation, Near-End Crosstalk
(NEXT), and Far-End Crosstalk (FEXT). This cable testing information is specified in
the ANSI/TIA/EIA-TSB-67 standard. Additionally, cables must also pass test
parameters for Return Loss and Equal-Level Far-End Crosstalk (ELFEXT). These
tests are specified in the ANSI/TIA/EIA - TSB-95 Bulletin, “The Additional
Transmission Performance Guidelines for 100 Ohm 4-Pair Category 5 Cabling.”
Note that when testing your cable installation, be sure to incl ude all patch cables
between switches and end devices.
Adjusting Existing Category 5 Cabling
If your existing Category 5 installation does not meet one of th e te st parameters for
1000BASE-T, there are basically three measures that can be applied to try to correct
the problem:
1. Replace any Category 5 patch cables with high-perform ance Category 5e
cables.
2. Reduce the number of connectors used in the link.
3. Reconnect some of th e connectors in the link.
