Chapter 9: Electrostatic Discharge Precautions
LGC340A 724-746-5500 | blackbox.com Page 53
9. Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in
modules or stand alone units, containing electronic components. Always
observe the following precautions when installing or handling these kinds of
products.
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component.
If the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
3. Hold the units by the edges; do not touch the electronic components or gold
connectors.
4. After removal, always place the boards on a grounded, static-free surface, ESD
pad or in a proper ESD bag. Do not slide the modules or stand alone units over
any surface.
WARNING! Integrated circuits and fiber optic components
are extremely susceptible to electrostatic discharge damage.
Do not handle these components directly unless you are a
qualified service technician and use tools and techniques that
conform to accepted industry practices.

Chapter 8: Fiber Optic Cleaning Guidelines
Page 52 724-746-5500 | blackbox.com LGC340A
8. Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely susceptible to
contamination by particles of dirt or dust, which can obstruct the optic path and
cause performance degradation. Good system performance requires clean
optics and connector ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a
reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.
2. Dust caps are installed at Black Box to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of connecting the
fiber cable to the device. If you need to disconnect the fiber device, reinstall the
protective dust caps.
3. Store spare caps in a dust-free environment such as a sealed plastic bag or box
so that when reinstalled they do not introduce any contamination to the optics.
4. If you suspect that the optics have been contaminated, alternate between
blasting with clean, dry, compressed air and flushing with methanol to remove
particles of dirt.

Chapter 6: Troubleshooting
Page 50 724-746-5500 | blackbox.com LGC340A
6. Troubleshooting
If a fiber connection cannot be established, perform the following to make sure
that the fiber transceivers on the IE GIGA MC TX/SFP are not over/under
driving the fiber receivers:
1. Make sure the fiber wavelength on both connected devices match (i.e. both
are 1310 nm single-mode fiber).
2. Make sure the twisted-pair port speed on the IE GIGA MC TX/SFP matches
that of the end devices connected to the IE GIGA MC TX/SFP Configure
the IE GIGA MC TX/SFP and its link partner to Auto Negotiation or, if using
Force mode, be sure speed and duplex match.
3. IE GIGA MC TX/SFP allows the end user to assign a VLAN tag to all
management traffic (SNMP and telnet). It is important to understand that IF
using telnet or iView2to assign a VLAN tag to management traffic then as
soon as this setting is saved the connectivity will be lost until the PC
becomes a member of the VLAN which was assigned to management
traffic.
If a VLAN tag has been assigned to management traffic and the end user
cannot re-establish a connection to the device via iView2or telnet, directly
connect a PC to the device via the serial cable and review/modify the
changes made (reference section on serial port config).

2. Overview: About the IE GIGA MC TX/SFP
The IE GIGA MC TX/SFP is an SNMP manageable standalone device
providing two fixed 10/100/1000Base-T copper ports and 2 SFP ports. The
SFP ports support fiber or copper SFPs. As a plug and play device, the IE
GIGA MC TX/SFP provides several distinct modes of operation to support a
wide range of applications. The IE GIGA MC TX/SFP provides OAM
functionality with 802.3ah (LINK-OAM ah) and 802.1ag (SERVICE-OAM ag)
supported on each port.It supports jumbo frame sizes of up to 10,240 bytes as
well as AutoCross on the copper ports. Power options for the IE GIGA MC
TX/SFP include both a standard low voltage wall transformer and a Power
Block for Office Battery or a DC Power Supply connection. As an Industrial
Ethernet device, it supports an extended temperature range of -40°C to +85°C.
A console port and a DIP Switch bay provide configuration options.
The IE GIGA MC TX/SFP can be directly managed, because it contains on-
board logic. Management capability is available if the device has firmware
version 123-00A1 or higher, which can be downloaded from the Black Box site.
iView2is a free software, posted on the website under Support/Downloads.
Please refer to page 12 for details.
The IE GIGA MC TX/SFP requires two small form-factor (SFP) modules which
provide greater flexibility in the network environment. The hot-swappable
nature of the SFPs, available in dual strand for Multi Mode and Single Mode,
and single strand fiber types for Single Mode, allow for easy configuration and
future upgrading as network demands evolve. The SFP modules must be
MSA-compliant and both DDMI and non-DDMI are supported.The fiber SFP
can support 100Mbps or 1000Mbps; while the copper SFPs support
10/100/1000Mbps and 1000Mbps.
SFPs are sold separately and meet Class 1 Laser Safety Standard.

3.1 Operations, Administration and Maintenance (OAM)
OAM is a general term used in network management and is typically applied to
a series of standard protocols for installing, monitoring, and troubleshooting
Metropolitan Area Networks.

Chapter 3: Configuration
Page 12 724-746-5500 | blackbox.com LGC340A
When applied to Ethernet – OAM is typically assumed to refer to the layer 2
(MAC layer), management protocols, specifically 802.3ah and 802.1ag. Layer
2 management protocols do not need higher level transport protocols to
operate, OAM data is transferred in standard multicast Ethernet frames.
802.3ah OAM:
(LINK-OAM)
Is a point-to-point protocol designed to verify a specific
link between two directly connected devices (over
copper or fiber), which support 802.3ah OAM. One
device must be configured to be an active OAM device,
the other a passive (typically the core switch would be
the active device, the end device passive). 802.3ah
OAM provides link status, remote fault detection and the
ability to initiate a loopback circuit.
802.1ag:
(SERVICE-OAM)
Often referred to as Connectivity Fault Management
(CFM), is an end-to-end protocol designed to verify a
specific network path between two devices that may well
be in different geographical locations. CFM allows the
network operator to administer, monitor and debug the
network using continuity check (a heart beat message),
link trace (similar to traceroot, but operating at the MAC
layer) and finally loopback (can be likened to a layer 2
ping).
3.2 iView² Management Software
iView² is the Black Box management software that features a Graphical User
Interface (GUI) and gives network managers the ability to monitor and control
the manageable Black Box products.
iView² is available in several versions, including a WebServer version 3.0, and
can also function as a snap-in module for HP OpenView Network Node
Manager and other third party SNMP Management software.
iView2supports the following platforms:
•Windows 2000
•Windows XP
•Windows Vista
•Windows 7
Please see the SNMP Management Module manual for software configuration
options.

3.3 iView2(iConfig view)
iView2(iConfig view) is an in-band utility created by Black Box, used for SNMP
configuration for Black Box’s SNMP-manageable devices.
The iView2(iConfig view) feature allows the following to be performed:
•Set an IP address, subnet mask and default gateway
•Define community strings and SNMP Traps
iView2(iConfig view) also includes an authorized IP address system and
restricted access to MIB groups which are supported by Black Box’s
manageable devices. These extra layers of security do not affect SNMP
compatibility. iView2(iConfig view) can upload new versions of the system
software and new MIB information. It also includes diagnostic capabilities for
faster resolution of technical support issues.
3.4 Configuration via DIP Switch Settings
The IE GIGA MC TX/SFP can be configured in one of the following ways via
DIP Switch settings:
Configuration
Method
Description
4-Port Switch
(default)
In this mode, the unit acts as a standard 4-port MAC-layer
switch. In this configuration, IEEE802.3ah Passive is
enabled on both fiber ports, and can be enabled on the RJ-
45 ports through the CLI.
Dual
Converter
mode
In this configuration, the unit functions as two independent
(SFP to TX) media converters and traffic never passes
between the two converters.
1+1 SFP
Protection
Non-Revertive
mode
In this mode, the “SFP A” port (fiber or copper) is connected
through the switch to the drop ports as the main link. The
“SFP B” port (fiber or copper) is active into the MAC switch,
but no connection inside the switch is made; in this way, the
“SFP B” line is held as the standby line. The “SFP B” line is
held in the LINK state for testing and line verification, but
does not actively carry user data.
When a fault is detected on the active line, all customer
traffic is switched to the “SFP B” port. With non-Revertive
mode data is not resumed by “SFP A” port.
1+1 SFP
Protection
Revertive
mode
In this mode, the “SFP A” port (fiber or copper) is connected
through the switch to the drop ports as the main link. The
“SFP B” port (fiber or copper) is active into the MAC switch,
but no connection inside the switch is made; in this way, the

5.3.8 Loopback Testing
The IE GIGA MC TX/SFP includes Loopback testing functionality. This feature
is selectable via iView2 within the OAM AH configuration. The menu of choices
for all ports includes:
•Terminate/initiate
•Process/ignore
OAM Loopback is controlled by using the “Loopback” and “Ignore Rx” control
parameters. Selecting “Initiate” from the “Loopback” control tells the client to
start a loopback process with the peer. Selecting “Process” from the “Ignore
Rx” control tells the client to process received loopback commands.
Only AH “Active” units can send a Loopback command to a remote unit. Either
Active or Passive AH units can respond to a Loopback command, but must be
configured to process these commands or they will be ignored.

end user to quickly access the device for some basic configuration capability.
Password protection is provided for the serial configuration process by pressing
Pon the main configuration screen. Enter a password, keeping in mind that
passwords are case-sensitive and must not exceed eight characters or include
spaces, and press Enter. This password will be requested whenever logging
on. To remove password protection, select Pand, instead of entering a
password, press Enter.
Passwords have the following requirements:
•The password must be between 1 and 8 characters long
•The password consists of a combination of any ASCII characters except
spaces
•Passwords are case sensitive
Passwords are a way to make the management of the Black Box devices
secure, but these password lists must be stored and maintained.
3.5.2.5 Assigning SNMP Trap Destinations
Traps are sent by the manageable device to a management PC when a certain
event takes place. To enter a trap destination, press T. When prompted, enter
a New IP Address prompt, enter the appropriate IP address of the destination
device and press Enter. Then, type the name of the community string (that the
destination device has been configured to accept) and press Enter. Select
whether the trap is for SNMP version 1 or 2c and press Enter. This function

enables ALL of the device traps. Supported traps include: Link Down, Link Up,
and Last Gasp.
3.5.2.6 Removing Trap Destinations
To remove all trap destinations, press K. Press Yto continue to confirm or Nto
abort and remove all trap destinations. Press Enter to finish.
This function will delete all trap destinations. To selectively delete trap
destinations or to disable/enable Traps, use iView2(iConfig view) to configure
the device.
3.5.2.7 Creating Community Strings
Community strings add a level of security to a network. The default community
string is named "public" and has read/write access. For security, "public"
should be replaced with custom community strings such as ones created with
read-only access (for general use), and another with read/write access (for the
administrator).
To create a new community string, go to the main configuration screen and
press C. Enter the name of the new community (up to 16 characters, no
spaces) and press Enter. Then type one of the following to assign the
community string’s access rights:
•R= read-only access
•W= read/write access
•Enter = abort
After entering Ror W, press Enter. To finish, press Enter and reboot.
3.5.2.8 Deleting Community Strings
To delete all community strings, perform the following:
Press U. The "Are you sure you want to delete all future strings?" prompt is
displayed. Press Ywhen prompted to proceed and delete all community
strings, Nto abort. Press Enter to finish.
This function will delete ALL community strings. To selectively delete
community strings, use iView2(iConfig view) to configure the device.
3.5.2.9 Ending the Session

3.5.2.10 Rebooting the Unit
To reboot the IE GIGA MC TX/SFP, type reboot from the main screen or the
command menu.
3.5.2.11 Enabling/Disabling DHCP
To toggle DHCP on the IE GIGA MC TX/SFP between enable and disable,
press Dand then Y. Press the Space Bar once to return to the main screen
without making any changes.
DHCP Disable (Static IP Addressing)
DHCP is disabled in the default configuration. Initially, modules are assigned a
Static default IP Address of 10.10.10.10. Changes to the Static IP Address can
be added manually through iView2(iConfig view) or a Console session. The
changes will be initiated following reboot of the module.
DHCP Enable (Dynamic IP Addressing)
If a DHCP server is present on the network and DHCP is enabled, the DHCP
client will initiate a dialogue with the server during the boot up sequence. The
server will then issue an IP address to the management card. Once the new IP
address is received, the SNMP Management Module will reboot so that the new
IP address will take effect. Refer to About Serial Port Configuration for more
information about Enabling/Disabling DHCP.
When there is no DHCP server on the network, use the serial configuration to
manually set the IP addresses.
When DHCP is enabled, the IP address (default 10.10.10.10 or a previously
used IP address, or user-configured) is saved. When DHCP is disabled, the
saved IP address will be reinstated and the device will reboot.
DHCP servers give out lease times: devices renew their leases based on the
administrator-specified time. If a device cannot renew its lease, and the lease
expires, the device will be given the IP address 10.10.10.10 and will reboot.
