Overview
Power Supply The PowerBlade PBC18 can be either an AC or DC powered chassis. The
expansion slot for the main power supply and the optional redundant
power supply are located on the back of the chassis. Refer to Figure 2 on
page 20.
The main and redundant power supplies can be “hot swapped,”
meaning that should either power supply fail, the failed power supply
can be removed and replaced with a new power module while the
chassis is operating. Network operations will not be interrupted. The
power modules to be hot swapped must be the same type. For example,
both power supplies must be AC or both must be DC.
Powering ON or OFF the chassis depends on the type of power supply
installed. For an AC model, you connect or disconnect the power cord.
For a DC model, you connect or disconnect the DC power cables or
power OFF the DC circuit to which the power supply is connected.
To install a power supp l y , refer to Installing a P ower Supply Modu le on
page 33. For instructions on hot swapping, refer to Hot Swapping a
Power Supply on page 42.
AC Power Supply
The AC power supply operates at 100-120/200-240 V AC with an input
frequency of 50/60 Hz at ± 3%. Figure 3 shows an PowerBlade PBC18
with an AC power supply.

The management module is an optional module used to monitor the
operating status of the media converters and switches installed the
PowerBlade PBC18. Refer to Figure 2 on page 20 for the location of the
expansion slot. The management module is not required for the chassis
to operate, but it is necessary if you want to locally or remotely monitor
and configure the modules and ports.
The management module features a Link, Power, and Status LEDs, as
well as a Reset button. (See Figure 5.) The LEDs and the Reset button are
duplicated on the front of the chassis for easy monitoring or to reset the
management module. You may need to reset the module after
completing the installation, adding or hot swapping a power supply, or
after upgrading the module’s firmware.

❑ Hot Swapping a Power Supply on page 42
Overview
There are two types of power modules available for the PowerBlade
PBC18: an AT-PBPWRAC and an AT-PBPWRDC. The AT-PBPWRAC is an AC
power supply module and the AT-PBPWRDC is a DC power supply
module.

An optional power supply share the load of powering the chassis with
the main power supply. This is known as “load-sharing.” In the event the
main power supply fails, the optional power supply will provide full
power to the chassis, thereby preventing a system failure.
The main and optional power supplies can be “hot swapped,” meaning
that should either power supply fail, the failed power supply can be
removed and replaced with a new power module while the chassis is
operating. Network operation will not be interrupted. The power
modules to be hot swapped must be the same type. You cannot install
an AC power supply and a DC power supply in the same chassis.
The back of the PowerBlade PBC18 has two expansion slots: one for the
main power supply and one for the optional power supply. The power
module installed in the PWR 1 expansion slot is for the main power
supply. The power module installed in the PWR 2 expansion slot is for
the optional power supply.
34
Powering ON or OFF the chassis depends on the type of power supply
installed. For an AC model, you connect or disconnect the power cord.
For a DC model, you connect or disconnect the DC power cables or
power OFF the DC circuit to which the power supply is connected.
Installing a Main Power Supply
To install a main power supply, perform the following procedure:
1. Remove the PWR 1 blank faceplate from the back of the chassis by
loosening the two thumbscrews, as shown in Figure 12.

This chapter describes the features and functions of the following
PowerBlade Media Converter modules:
❑ AT-PB10 Series Modules on page 51
❑ AT-PB100 Series Modules on page 56
❑ AT-PB300 Series Modules on page 65

43
Installing a Media Converter Module
Overview
The PowerBlade Media Converters are designed to extend the distance
of your network by interconnecting LAN devices that are physically
separated by large distances.
There are several different PowerBlade modules that you can “mix and
match” in a chassis. The media converter modules come in a variety of
port configurations, connectors types, and operating distances.
PowerBlade Media Converters are available with an RJ-45 twisted pair
connector and either an BNC standard thin Ethernet connector or a FJ,
LC, MT-RJ, SC, ST, or VF-45 fiber optic connector. Depending on the
model, the media converters feature a maximum operating distance of
100 meters (328 feet) to 100 kilometers (62 miles).
44
PowerBlade PBC18 Installation Guide
Common Features
The following is a list of features common to most PowerBlade Media
Converter modules:
❑ LEDs for unit and port status
❑ MDI/MDI-X feature that eliminates the need for a crossover cable
(except for the AT-PB1000 Series)
❑ Link Test feature performs a link test on the module’s port
❑ MissingLink™ notifies end-nodes of link failures
❑ Half-duplex or full-duplex operation
MDI/MDI-X An RJ-45 port on a 10 Mbps or 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI or MD I-X. The RJ- 45
port on a PC, router or bridge is typically wired as MDI, while the twisted
pair port on a switch or hub is usually MDI-X.
Note
This feature is available for all PowerBlade modules except for the
AT-PB1000 Series.
To connect two 10 Mbps or 100 Mbps network devices together that
have dissim ilar p ort wiri ng configu rati ons, such as MDI t o MDI-X , you use
a straight-through cable. To connect two network devices that have an
RJ-45 port with the same wiring configuration, such as MDI to MDI, you
use a crossover cable.
The PowerBlade 10 Mbps and 100 Mbps media converters that have an
RJ-45 port feature an MDI/MDI-X button. You can use this button to
configure the twisted pair port on the media converter as either MDI or
MDI-X, thus eliminating the need for a crossover cable regardless of the
type of network device you are connecting to the unit.

Link Test/
MissingLink
The Link Test/MissingLink (LT/ML) button or switch, depending on your
module, allows you to perform a link test on the media converter ports
and to activate the MissingLink feature on the unit. Both features are
describe in the following section.
Link Test
The link test is a fast and easy way for you to test the connections
between the media converter ports and the end-nodes that are
connected to the ports. If a network problem occurs, you can perform a
link test to determine which port is experiencing a problem, and be able
to focus your troubleshooting efforts on the cable and end-node where
the problem resides.
A link test is performed when the LT/ML button or switch is in LT
position. For instructions on performing a link test, refer to
Troubleshooting on page 99.
Note
Performing a link test does not interfere with a media converter’s
ability to pass network traffic, except for the AT-PB1000 Series
modules.
46
PowerBlade PBC18 Installation Guide
MissingLink
The MissingLink feature enables the ports on the media converter to
pass the “Link” status of their connections to each other. When the
media converter detects a problem with one of the ports, such as the
loss of connection to a end-node, the media converter shuts down the
connection to the other port, thus notifying the end-node that the
connection has been lost.
For example, if the network twisted pair cable on a AT-PB101 were to fail,
the module would respond by dropping the link on the fiber optic port.
In this way, the AT-PB101 notifies the end-node connected to the fiber
optic port that the connection on the twisted pair port has been lost. If
the failure had started with the fiber optic cabling, the unit would drop
the link to the twisted pair port.
The value to this type of network monitoring and fault notification is that
some hubs and switches can be configured to take a specific action in
the event of the loss of connection on a port. In some cases, the unit can
be configured to seek a redundant path to a disconnected end-node or
send out a trap to a network management station, alerting the network
administrator of the problem.
Note
MissingLink is disabled when you perform a link test with the
MissingLink/Link Test feature. Consequently, to ensure that the
MissingLink is enabled on the media converter, always set the
ML/LT to the ML position during normal network operations.
47
Installing a Media Converter Module
Half-duplex and
Full-duplex Mode
Duplex mode refers to the way an end-node sends and receives data on
the network. An end-node that is operating in half-duplex mode can
either send data or receive data, but it cannot do both at the same time.
An end-node that is operating in full-duplex mode can send and receive
data simultaneously. The best network performance is achieved when
an end-node can operate at full-duplex, since the end-node is able to
both send and receive data simultaneously.
All of the PowerBlade Media Converters are transparent to the duplex
mode of the end-nodes that are connected to their two ports. That is, a
PowerBlade Media Converter can operate with end-nodes operating at
either half-duplex or full-duplex mode. However, the two end-nodes
connected to the ports on a PowerBlade Media Converter must operate
with the same duplex mode.
For example, assume that the 100Base-TX port on an AT-PB102 is
connected to a port on an AT-FH705E hub configured for half-duplex
operation, while the 100Base-FX port is connected to a port on an
AT-8224XL switch configured for full-duplex operation. This would be an
invalid configuration and could adversely impact the performance of the
network. Either the port on the AT-FH705E hub connected to the
100Base-TX port would have to be changed to full-duplex (if it supports
that capability), or the port on the AT-8224XL switch connected to the
100Base-FX port would need to be changed to half-duplex.
48
PowerBlade PBC18 Installation Guide
Network
Topologies
The PowerBlade Media Converters can be used in two different
topologies: standalone and back-to-back. Both types of topologies are
described below.
Standalone Topology
A standalone topology is when one media converter is used to
interconnected two end-nodes. Figure 19 illustrates a standalone
topology that uses one AT-PB1001/1 module to interconnect two
remote campuses. Campus 1 has an AT-8224XL switch with an
AT-A15/LX expansion module connected to the 1000Base-LX port on the
AT-PB1001/1. Campus 2 has an AT-8216FXL switch with an AT-A15/SX
expansion module connected to the 1000Base-SX port on the
AT-PB1001/1.

Installing a Media Converter Module
Back-to-back Topology
A back-to-back topology is when two media converters are used to
interconnect the end-nodes. Figure 20 illustrates a back-to-back
topology that uses an AT-PB1001/4 and an AT-MC1001 media converter
to connect two remote campuses. Campus 1 has an AT-8224XL switch
with an AT-A15/SX expansion module connected to the 1000Base-SX
port on the AT-PB1001/4. The 1000Base-LX port on the AT-PB1001/4 is
connected to the 1000Base-LX port on the AT-MC1001. The 1000Base-SX
port on the AT-MC1001 is connected to the AT-8224XL switch at Campus
2.
In this example, the two media converters are used both to extend the
distance of your network and also convert the fiber optic cable from
multimode to single-mode and back again.

802.3u) of the media converter. In most configurations you should leave
the auto-negotiation feature enabled so the unit can automatically
determine the appropriate duplex mode, based on the capabilities of
the end-nodes. For example, the auto-negotiation feature on the media
converter should be left enabled in situations where both end-nodes are
also capable of auto-negotiation or where both end-nodes have been
pre-set to the same mode, such as half-duplex. Figure 25 shows the
location of the auto-negotiation switch for the AT-PB100 Series Media
Converters.

Figure 25 Auto-negotiation Switch
There is one situation, however, where it may be necessary to disable the
auto-negotiation feature, and that is to prevent a mismatch from
occurring between the duplex modes of the end-nodes. For example,
Figure 26 shows two units that have been connected with a AT-PB100
Series Media Converter. Unit 1 is an Ethernet hub that is capable of
operating in half-duplex mode only. Unit 2 is a switch that can operate in
either half- or full-duplex mode, and will auto-negotiation the duplex
mode.
63
Installing a Media Converter Module
In attempting to auto-negotiate with Unit 1, the media converter will
determine that the unit is capable of half-duplex only and will set the
port connected to the unit appropriately. In auto-negotiating with Unit
2, the media converter will determine that the unit can manage fullduplex and will set the port connected to the unit to full-duplex. The
result is a mismatch, with one port on the media converter operating in
half-duplex and the othe r port operating i n full-duplex. This is referred to
as a common duplex mode mismatch and will result in poor network
performance between the end-nodes.

Unit 2: Ethernet Switch
(Auto-negotiate)
Figure 26 Example of a Duplex Mode Mismatch
You can resolve a duplex mode mismatch in one of two ways:
❑ Manually configure one of the units so that its duplex mode
matches the other end-node. In the example, you could configure
Unit 2, if possible, so that the port connected to the media
converter is set to half-duplex.
❑ Disable auto-negotiation on the media converter using the auto-
negotiation switch. With auto-negotiation on the media
converter disabled, an end-node that auto-negotiates will assume
that the media converter is capable of only half-duplex operation.
In the example, with auto-negotiation disabled on the media
converter, Unit 2 will automatically set its port to half-duplex, thus
eliminating the mismatch in duplex modes between the endnodes.

Installing a Media Converter
This section explains how to install a PowerBlade Media Converter
module in the chassis. It is not necessary to power OFF the chassis to
install a module.
To install a media converter module in the chassis, perform the following
procedure:
1. Remove a blank faceplate from the chassis’ front panel by loosening
the thumbscrew. A media converter module can be installed in any
expansion slot. See Figure 29.

Note
Do not remove a blank faceplate covering an expansion slot unless
you intend to install a PowerBlade module.
2. Remove the module from the shipping package and store the
packaging material in a safe location.
Caution
Wear a grounding device and observe electrostatic discharge
precautions when installing the PowerBlade module in the chassis.
Failure to observe this caution could result in damage to the
PowerBlade module.
3. For an AT-PB15 module, check the setting of the J5 jumper. If your
chassis does not contain an AT-PBM02 management module, set
the jumper to the Enabled (RIGHT) position. The default setting is
Disabled (LEFT) indicating the management module is installed.
Refer to Figure 23 on page 54 for the location of the jumper.

The performance specifications are listed below:
Performance
❑ 148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire
speed forwarding and filtering
❑ 200 Mbps maximum throughput in 100 Mbps, full-duplex mode
❑ 20 Mbps maximum throughput in 10 Mbps, full-duplex mode
❑ Up to 8,192 unicast MAC addresses and unlimited
multicast/broadcast addresses
❑ 280 kilobytes (per port) packet buffer
❑ Low latency 14.3 µs (64-byte packet, 100 Mbps full-duplex)
Frame Processing The PowerBlade Switch modules support store and forward switching at
Fast Ethernet full-wire speed either in 10 or 100 Mbps, half- or full-duplex
mode. Packets entering each port are stored in buffers. After the full
packet is received, it is forwarded or discarded depending on its
destination address and error status. This ensures that only error-free
data packets destined for another segment will be transferred across the
switch, reducing network load. For example, if the packet entering from
Port 1 is destined for an end station on Port 2, it will be forwarded if the
Frame Check Sequence (FCS) is valid. If the packet from Port 1 is destined
for an end station also attached to Port 1, then the packet is discarded.
Address
Recognition and
Filtering
The switch will discard CRC error, misaligned, runt, and undersized/over-sized packets. When the packet has dribble bits at the end,
the switch will truncate to octet boundary and check for a good FCS
before forwarding.
Up to 4,000 MAC addresses can be stored in the MAC address table in
the switch modules. The switch will learn all new addresses in real-time
after power-up with its address self-learning mechanism. If the source
address of an incoming packet is not found in the address table, the
switch updates its MAC address table. Because the switch has Automatic
Address Aging, if a source address entry in the table is not updated
within five minutes, the entry is deleted from the table. The switch
forwards all multicast, broadcast, and unicast packets when the MAC
address table size is exceeded.

AUTO Green The 10/100Base-TX port is auto-negotiating.
MDI/MDI-X An RJ-45 port on a 10 Mbps or 100 Mbps Ethernet network device can
have one of two possible wiring configurations: MDI and MDI-X. The
RJ-45 port on a PC, router or bridge is typically wired as MDI, while the
twisted pair port on a switch or hub is usually MDI-X.
To connect two 10 Mbps or 100 Mbps network devices together that
have dissim ilar p ort wiri ng configu rati ons, such as MDI t o MDI-X , you use
a straight-through cable. To connect two network devices that have an
RJ-45 port with the same wiring configuration, such as MDI to MDI, you
use a crossover cable.
The PowerBlade 10 Mbps and 100 Mbps switches that have an RJ-45
port feature an MDI/MDI-X button. You can use this button to configure
the twisted pair port on the switch as either MDI or MDI-X, thus
eliminating the need for a crossover cable regardless of the type of
network device you are connecting to the unit.

DIP Switches The DIP switches are used to manually configure the operating
characteristics of the ports. These characteristics include the port speed,
duplex mode, and auto-negotiation.
On the 100Base-FX fiber optic port, you can manually set the duplex
mode to either half-duplex or full-duplex.
On the 10/100Base-TX twisted pair port, you can manually set the speed
of the port to either 10 Mbps or 100 Mbps, set the duplex mode to either
half-duplex or full-duplex and enable or disable auto-negotiation.
Enabling auto-negotiation will automatically set the port’s speed and
duplex mode.
The DIP switches are located on the board. Refer to Figure 32.

When setting the DIP switches, consider the following:
❑ For a twisted pair port(s), setting the AUTO NEG switch to either
ON or OFF enables or disables auto-negotiation on the port. If you
disable auto-negotiation, be sure to set the DIP switches for the
port’s speed and duplex mode to match the speed and duplex
mode of the end-node.
❑ For a fiber optic port, set the port’s duplex mode using the
appropriate DUPLEX MODE DIP switch. This setting must match
the duplex mode capability of the end-node to be connected to
the port.
J6 Jumper The AT-PB200 and AT-PB202/x Series Switch modules feature a J6
jumper. There are two possible jumper settings: Enable and Disabled. If
the chassis does not contain an AT-PBM02 management module, set the
J6 jumper to the Enable (RIGHT) position. If the chassis contains an
AT-PBM02 management module, set the J6 jumper to the Disabled
(LEFT) position. Disabled is the factory default setting. Refer to Figure 33
for the location of the J6 jumper.

PowerBlade PBC18 Installation Guide
This section explains how to install a PowerBlade Switch in the chassis. It
is not necessary to power OFF the chassis to install the switch.
Be sure to observe the following guidelines when planning the
installation of the AT-PB200 and AT-PB202/x Series Switch.
❑ The end-node connected to the fiber optic port on an AT-PB200
or AT-PB202/x Series Switch must be able to operate at 100 Mbps.
❑ The end-node connected to the twisted pair port(s) can operate at
either 10 Mbps or 100 Mbps.
To install the switch, perform the following procedure:
1. Remove a blank faceplate from an empty expansion slot on the
front of the chassis. The module can be installed in any expansion
slot. See Figure 35.
Figure 35 Removing a Blank Faceplate
Note
Do not remove a blank faceplate covering an expansion slot unless
you intend to install a PowerBlade module.
2. Remove the module from the shipping package and store the
packaging material in a safe place.
Caution
Wear a grounding device and observe electrostatic discharge
precautions when installing the PowerBlade module in the chassis.
Failure to observe this caution could result in damage to the
PowerBlade module.
89
Installing a Switch Module
3. Check the setting of the J6 jumper. If the chassis does not contain an
AT-PBM02 management module, set the jumper to Enabled (RIGHT).
The factory default setting is Disabled (LEFT) indicating that an
optional management module is installed. See Figure 33 on page 83
for the location of the jumper.
Note
If you have an earlier version of an AT-PB200 or AT-PB202/x Series
Switch (without a J6 jumper) and are using an AT-PBM02
management module to manage the chassis, the ML LED on the
switch may not function properly.
4. Configure the DIP switches. Refer to Table 37 for the possible
settings and Figure 32 for the location of the DIP switches. See DIP

Chapter 6
Installing an Optional Management
Module
This chapter describes the features and functions of the PowerBlade
Optional Management Module. This chapter also provides the
procedure for:
❑ Installing an Optional Management Module on page 96
Overview
The AT-PBM02 is an optional management module for the PowerBlade
PBC18. When installed, the management module allows you to monitor
the operating status of the media converters and switches installed the
chassis. The management module is not required for normal network
operations, but it is necessary if you want to locally or remotely monitor
and configure the modules installed in the chassis and the ports on the
modules.
The management module features a RS-232 terminal port with a DB9
connector. The terminal port is used for local management. The
AT-PBM02 also features a 10Base-T twisted pair port with an RJ-45
connector. The twisted pair port is used for remote management. The
RJ-45 has a maximum operating distance of 100 meters (328 feet) and
supports 10 Mbps half-duplex operation.
93
Installing an Optional Management Module

5. Secure the management module to the chassis by tightening the
two thumbscrews.
6. Apply power to the chassis by connecting the AC power cord or DC
wires. Refer to Step 5 on page 36 for an AC unit or Step 6 on page 36
for a DC unit.
7. Check to be sure that the Status and PWR LED on the front of the
management module are green.
8. For local management, attach one end of an RS-232 cable with a
DB9 connector to the RS-232 port on the management module and
the other end of the cable to a terminal or PC with a terminal
emulator program.
9. For remote management, connect a Category 3 or better twisted
pair cable with an RJ-45 connector to the 10Base-T port on the
management module and connect the other end of the cable to a
10 Mbps or a 10/100 Mbps port on an Ethernet hub or switch.
10. Set the MDI/MDI-X switch for the 10Base-T port. If the 10Base-T port
is connected to an Ethernet hub or switch, the correct setting for the
switch is probably the MDI (IN) position.

Troubleshooting
Follow the guidelines in this section to test and troubleshoot the
installation in the event a problem occurs.
Chassis
Verify that the PWR1 main power supply and PWR2 optional power
supply LEDs are green. If one of the LEDs is OFF, do the following:
❑ Check to be sure that the power supply is securely connected to
the power outlet.
❑ Check to be sure that the power supply is securely seated in the
chassis.
❑ For a DC unit, check to be sure that the wires are connected to the
correct terminals.
❑ Check to be sure that the fans are operating. If a fan is not
operating, it is likely that a power supply has failed.
99
Troubleshooting
Media Converter or Switch Module
If the PR LED on the module is OFF, do the following:
❑ Check that the module is securely seated in the chassis.
❑ Check that the chassis is receiving power.
❑ Try installing the module in another expansion slot.
If a LK LED on the module is OFF, do the following:
❑ Check that the end-node connected to the port is ON.
❑ Check to be sure that the cable is securely connected to the ports
on the module and on the end-node.
❑ Check to be sure that the appropriate type of cable for the port is
being used.
❑ For the fiber optic port, check that the maximum allowable loss
budget has not been exceeded.
If the LK LED is green but there is a communication problem between
the end-nodes connected to the module (and you are not running a link
test), check the following:
❑ For a media converter module, check to be sure that the end-
nodes connected to the ports are operating at the same speed
and at a speed appropriate for the PowerBlade model.
❑ For a media converter module, check that the end-nodes are
operating in the same duplex mode.
❑ For a media converter module, check that the Link
Test/MissingLink button is in the M/L ON (IN) position.
❑ Check that the maximum allowable loss budget for the fiber optic
cable has not been exceeded.
❑ For a switch module, check to be sure that the DIP switches are set
correctly.
