Preparation
You can mount the CoreBuilder 7000 family ATM switch in a 19-inch
distribution rack. This section describes how to prepare the unit and the
distribution rack, and mount the unit in the distribution rack. Please read
all of the instructions carefully before beginning the installation.
For the basic mechanical and space requirements for the distribution rack,
see “Distribution Rack Requirements” on page 107.
To prepare the CoreBuilder 7000 family ATM switch and distribution rack
for installation:
Attach the mounting brackets onto the sides of the CoreBuilder 7000
1
family ATM switch using the mounting bracket screws (M4 x 8 Phillips).
Determine whether or not the distribution rack has threaded holes. If the
2
holes are threaded, see “Mounting the CoreBuilder 7000 Family ATM
Switch” on page 28.
If the holes are not threaded, you must insert “G” clips. To determine
3
where to insert “G” clips, locate the top of a universal mounting hole
pattern on the left mounting rail. In the universal rail pattern, the spacing
between holes is 1/2 inch, 5/8 inch, 5/8 inch, and 1/2 inch. To find the top
of the pattern, locate the midpoint between any two holes that are
spaced half an inch apart. Figure 2 shows the universal mounting hole
pattern.

Safety Precautions
When handling replacement parts, 3Com recommends that you always
use a wrist strap connected to a proper ground. This helps prevent the
module from being damaged by electrostatic discharge. Additionally,
when not in use, the module should be stored in an antistatic bag.
If the system is powered on when you are replacing a module, do not
insert any metal objects, such as a screwdriver or a finger with jewelry, in
the open slot. This could cause burns or other bodily harm, as well as
system damage.

Vorsichtsmaßnahm
en
Mesures de sécurité
Wenn Sie Ersatzteile handhaben, benutzen Sie immer ein Band am
Handgelenk, daß gut geerdet ist. Das hilft vermeiden, daß das Ersatzteil
durch elektrostatische Entladung beschädigt wird. Darüber hinaus sollte
ein Modul, wenn nicht benutzt, in einem antistatischen Beutel
aufbewahrt werden.
Steht das System unter Strom, wenn sie ein Modul installieren oder
auswechseln, führen Sie keine Metallgegenstände, wie einen
Schraubenzieher oder einen Finger mit Schmuck in den offenen Schlitz
ein. Das könnte zu Verbrennungen oder anderen Körperschäden führen,
sowie auch zu Schäden am System.
Lors de la manipulation des pièces de rechange, 3Com recommande de
toujours utiliser une bande attachée au poignet et reliée à la terre. Cela
aidera à éviter que la pièce ne soit endommagée par une décharge
électrostatique. De plus, lorsqu'il n'est pas utilisé, le module doit être
conservé dans un emballage antistatique.
Power Supply
Module
Si le système est alimenté lors de l'installation ou du remplacement d'un
module, ne jamais insérer d'objet métallique tel qu'un tourne-vis ou un
doigt portant un bijou dans la fente. Cela est susceptible de provoquer
brûlures ou autres dommages corporels, et d'endommager le système.
The CoreBuilder 7000 family ATM switch provides a dual load-sharing
power supply capability where the second unit can serve as a redundant
power supply. For more information, see “Redundant Power Supply” on
page 85.
For certain combinations of installed interface cards, the second power
supply cannot be used as a redundant supply (see “Providing Redundancy
for Various Power Loads” on page 90).

Hot-Swapping a Switch Module or Interface Module
This section describes procedures for installing and setting up both a
main and redundant switch module together.
Two different setup procedures are described. The first procedure covers
setting up the main and redundant switch module
hardware redundancy
without setting up LANE redundancy. This procedure only requires
operating the LMA. The second procedure sets up the main and
redundant switch module hardware redundancy as well as LANE
redundancy. It requires both the LMA and the Transcend Enterprise
Manager.
There are two situations where you would use the procedures of this
section:
The initial installation of main and redundant cards.

NSTALLING AND CONNECTING COREBUILDER MODULES
General Description of the Procedure
The following is a general description of the procedure for orientation
purposes only. When you perform the procedure, use the detailed steps
in the following sections.
Install both switches in chassis and run CFGFRMAT.BAT on each one.
1
Connect Ethernet ports of each switch module and install at least one
interface card in the chassis.
Configure the first switch using the Integrated Fast Setup of the LMA and
2
do not reboot the switch in the Integrated Fast Setup.
Reboot the switch after one minute using the LMA menu.
3
Answer “no” to the prompt “Erase the setup parameters?” and use the
4
LMA to check that all configuration parameters (i.e., database, IP, NNI
etc.) have passed successfully to the second switch module.
Configure LANE redundancy in the first switch using the Transcend
5
Backbone and Services Setup window and close the window when
finished.
Reboot the switch after one minute
6
Configure LANE redundancy in the second switch module using the
7
Transcend Backbone and Services Setup window and close the window
when finished.
After one minute use the MIB browser to check the LECS order list and
8
the Backbone and Services Setup window to check the LECS database.
Reboot the box.
9
Check the second switch using the MIB browser to check the LECS order
10
list and the Backbone and Services Setup window to check the LECS
database.
Preparatory Steps
Carry out the following preparatory steps.
Install main and redundant switch modules in the switch module slot 1
1
and slot 2 respectively (see“Installing a Switch Module” on page 32
not run the Integrated Fast Setup yet.
Each time the switch is rebooted during this procedure the cards change
roles. The main card becomes the redundant card and vice versa. The
main card can always be identified by its ACT LED flashing once every
two seconds. The ACT LED of the redundant card flashes at a lower rate.
). Do
Switch Module
Verify that at least one interface card of any type is installed in the
2
CoreBuilder chassis in any interface card slots 3-6. Data is transferred
between switch modules via a communications chip on an interface card.
Verify that the Ethernet management ports in both switches are
3
connected to the NMS station. They can either be connected through a
hub to the NMS station or through an Ethernet interface card in the same
chassis, such as the CoreBuilder 7400 High Density Ethernet/ATM
interface card, to the NMS station.
During the procedure you will need to verify connectivity between the
NMS station and the switch by pinging the switch module from the NMS
station.
Connectivity between the switch module and its attached devices is
established by a coldStart trap transmitted by the switch module when it
boots. The coldStart trap causes a device to learn the MAC address of the
switch module. However, there are certain devices, for example, a Solaris
station, which will not learn a new MAC address for an IP when one
already exists. If you are using one of these devices as an NMS station,
and you are unable to ping the switch module, try erasing the switch
module’s MAC address from the device’s ARP table and ping again.
37
Verify that the RS-232 terminal line is connected to the console port on
4
the main switch module.
Procedure Execution
Reset the configuration of both switch modules by executing the
1
CFGFRMAT.BAT file supplied with your software.
To execute the CFGFRMAT.BAT file proceed as follows:
Perform the LMA command (1) SYS / (3) LOA / (3) LCL / 1 to put the
a
system in Load Mode: Load.
Reboot the switch using the LMA menu command: (1) SYS / (7) RBO.

Verify that the ELAN names in the LECS database are identical in both
7
switch modules. Use menu item (2) LEM/(1) LCS/(5) LNT to check that the
LECS database of the second switch includes the ELAN name of the first
switch. For example, Elan6666_0 - Elan6666_15

To connect a terminal to the CoreBuilder 7000 family ATM switch control
port:
Connecting to the
Ethernet Port
Prepare an RS-232 shielded cable (9 pin-to-9 pin or 9 pin-to-25 pin, as
1
dictated by the terminal you wish to use).
Configure the terminal: 19200 baud, 8 data bits, 1 stop bit, no parity,
2
xon/xoff flow control.
Push the DCE side of the cable onto the Control port of the switch
3
module and screw it into place.
Connect the other end of the cable to the terminal.
4
In case you have installed a redundant switch unit, it is sufficient to
connect the RS-232 line to either the active switch control port or to the
redundant switch control port.
The Ethernet port is used for connecting directly to a Transcend Network
Management System terminal for management purposes.
Connecting to Network Devices
47
In case you have installed a redundant switch module, its Ethernet port
must also be connected directly to the Transcend NMS terminal.
Another way of connecting the Ethernet port to an out-of-band Ethernet
network is to connect it to a CoreBuilder 7200 Ethernet/ATM Interface
Card or a CB7400 High Density Ethernet/ATM Interface Card installed in
the same chassis.

This section describes the stages of system power-on of the CoreBuilder
7000 family ATM switch.
Apply electrical power to the system by inserting the power cord in the
power supply unit. The power supply indicator lights and the CoreBuilder
7000 family ATM switch automatically runs diagnostic software. This
software verifies that every component in the system is fully functional
before the system becomes active on the network. Diagnostics should
take sixty seconds or less.
If any component fails power-on diagnostics, the system either fails to
power on or it keeps faulty modules off-line. Once the system comes up,
you can check to see which modules, if any, have failed diagnostics by
checking the LED panels; in-depth information is available by viewing the
system configuration screens on the administration console.
Indicators
4-Port Interface
Module LEDs
All interface and switching unit indicators light at the start of the
power-on diagnostic sequence, then go out briefly. General activity LEDs
light up as the system checks the switching and interface modules. Finally,
individual port indicators go on as the system discovers active
connections residing on the interface modules. The 10BaseT indicator on
the interface module is on during normal function, even if there is no
active 10BaseT management link.

Use the Integrated Fast Setup procedure to configure the minimum set of
parameters needed to enable the CoreBuilder 7000 family ATM switch
and its attached devices to function in the network.
With this procedure you can configure both the CoreBuilder 7000 family
ATM switch card and all CoreBuilder 7X00 interface cards installed in it in
one session.
Integrated Fast Setup
57
In certain cases you will need to use the Fast Setup procedure of
individual CoreBuilder 7X00 interface cards, in addition to the Integrated
Fast Setup procedure, to correctly configure your system.
This section presents the Integrated Fast Setup of the CoreBuilder 7000
family ATM switch card. It also explains when to use the Integrated Fast
Setup of the CoreBuilder 7000 family ATM switch card and when to use
the Fast Setup of an individual Corebuilder 7X00 interface card. For
detailed information about how to use the Fast Setup of an individual
Corebuilder 7X00 interface card, see the User Guide of the specific
interface card.
Chassis-oriented Setup
The Integrated Fast Setup procedure is based on the concept that the
CoreBuilder 7000 family ATM switch chassis together with its installed
interface cards is viewed as an integrated unit. The advantage of this
point of view is its simplicity: it is not necessary to remember in which slot
each interface card is installed or even which type of interface card is
installed. Attention is focussed on configuring the ports of the chassis.
The procedure automatically determines the ports that are available in the
chassis and presents them by type (Ethernet, Fast Ethernet, ATM) for
configuration. The port location is displayed by the notation <slot.port>
For example <3.1> refers to slot #3, port #1.
.
Chassis-wide VLANs
With the Integrated Fast Setup, Virtual LANs (VLANs) can be created
across the entire chassis. VLANs are set up in two stages. First, in the LE
Client section, a number of
potential
VLANs are created according to the
requirement of the network. Next, in the Virtual Network Configuration
section, the potential VLANs become actual VLANs by having ports
assigned to them.
You need to define an administration “admin” VLAN to maintain SNMP
connectivity to each device in the network. Using the Integrated Fast
Setup you define one admin VLAN for the chassis; there is no need to
define separate admin VLANs for each interface card.
Note that from software version 3.5 on, the “admin” VLAN can now be
called by any other name providing the same name is used consistently in
the CB7000 and in all installed CB7X00 interface cards. When using the
Integrated Fast Setup, the name for the admin VLAN which is specified
for the switch module will be automatically chosen for the other modules

Setup Modes
The Integrated Fast Setup provides two setup modes: the “Full” setup
mode and the “Switch” setup mode.
Full Setup Mode
The Full setup mode configures both the CoreBuilder 7000 family ATM
switch and the installed interface cards. It sets the required parameter
values in all the installed interface cards. The Full setup mode presents
only the most critical parameters; default values are assumed for the
remaining parameters.
This method is recommended for most users, especially for initial setup.
Only those systems that require specific parameter settings in one or
more of the installed interface cards will require the Switch setup mode
described in the next section.
Switch Setup Mode
The Switch setup mode focuses only on the CoreBuilder 7000 family ATM
switch and its ATM ports. The Switch setup mode allows you to retain
special settings in the interface cards. In this mode, the installed interface
card configurations cannot be changed. If you want to alter the settings
in an interface card, use the Fast Setup of that interface card after you are
finished using the Switch setup procedure.
Setup Mode Selection
If one of the following conditions is detected, the operator is prompted
to choose between the Switch and Full setup modes:
A Subnet Mask, Default Gateway or NMS Address different from that
■
of the CoreBuilder 7000 family ATM switch
A VLAN whose ATM connection is set to “No”
■
The name of the ELAN to which the default admin port (Port #1 in
■
each slot) is attached is not the same in all interface cards.
If none of these situations is detected, Full setup mode is automatically
selected.
Integrated Fast Setup
If Full setup is selected, the parameters in the interface cards revert to
their default values.
Setting Special Parameters
If one or more individual interface cards requires one of the special
situations referred to in the previous section or needs to remain
unaltered, you need to do one of the following:
Use the Switch setup mode of the Integrated Fast Setup to set up the
■
CoreBuilder 7000 family ATM switch only and then use the Fast Setup
of each installed interface card separately.
Use the Full setup mode of the Integrated Fast Setup to configure the
■
CoreBuilder 7000 family ATM switch and all installed interface cards
and then use the Fast Setup for the particular interface card in order to
restore its special parameter values.

FastBUS Configuration Section
This section prompts you to
configure the FastBUS module. If no FastBUS module is installed, this
section is skipped by the Integrated Fast Setup.
This section prompts you for the ATM interface
type configuration of the ports on the Interface Modules which are
installed in the CoreBuilder 7000 family ATM switch chassis.
There are four interface types: UNI, E-IISP, IISP and PNNI. The UNI type is
normally used when an edge device is connecting to a switch. The E-IISP
type is normally used when connecting to another CoreBuilder 7000 or
9000 switch. The IISP type is used to connect to a device which does not
recognize the E-IISP protocol used by the CoreBuilder 7000 family ATM
switch such as switches of other vendors. The PNNI type is normally used
to connect switches to other similar or different types of switches when
you want each switch to have a global view of the entire network.
PNNI is available in version 4.5 extended only.
To enter the interface type configuration:
At the NNI type of port prompt, enter the NNI type for the port you just
1
specified. Enter “U” for UNI, enter “E” for E-IISP, enter “I” for IISP, or “P”

Additional Switch Configuration
73
Configuring SVCs
CoreBuilder 7000 family ATM switches use standard UNI 3.0, 3.1 or 4.0
switched virtual channel (SVC). SVC mode can be used when CoreBuilder
is in a backbone or workgroup topology, with PVC used whenever
necessary. ILMI enables automatic address registration for SVC. Addresses
can be registered manually via the LMA menus.
Changing the UNI Version
The CoreBuilder will run UNI 4.0 SVC by default. You can work in UNI 3.0
or UNI 3.1 by choosing this option in the signalling setup menu.
Configuring Network Prefix and ATM Addresses
ATM addresses are essential for establishing a connection using SVC.
Most devices that support SVC, also support automatic address
registration through the ILMI protocol.
A network prefix is essential for address registration to be executed. Refer
to
CoreBuilder 7000 Family ATM Switches Management Guide
for proper
network prefix setting.
For connectivity with devices that do not support ILMI, ATM addresses
can be set manually using the Add ATM address function under ATM
address setup in the Administration Console menus.
Configuring a PVC
Permanent Virtual Channels (PVC) can be used to connect to devices that
do not support switched virtual channels (SVC) standard protocols. In the
CoreBuilder 7000 family ATM switch you can create point-to-point (P2P)
and point-to-multipoint (P2M) connections. Use the Setup and
Configuration Connections menu, to create a PVC call, PTP or PTM. You
can also create an out VC in a PTM call, release a PVC call, release an out
VC from call, save PVC connections in flash memory and reset saved
connections. Up to 2000 PVCs can be configured.
Configuring Clock Synchronization
External clock synchronization allows a clock to be received on one of the
bottom of 4 OC-3c ports of an 8-port interface card from an external
source, and to be distributed to all bottom OC-3c ports on the same card
and other 8-port interface cards in the same chassis. It is used in voice
and data applications so that the same port is used at the same time. You
can configure one port to be the master port which will distribute its

At any time after configuring the CoreBuilder 7000 family ATM switch,
you can view the available statistics to see how the network is
functioning. For example, you may want to display the general statistics
for an overview of the network, or the signalling statistics for protocol
information on specific ports. Table 17 lists the types of statistics

You can store (upload) the configuration of an installed card from its flash
memory to an external disk and restore it (download) to the flash memory
of the original card — or to the flash memory of a different card of the
same type — at a later time. You can initiate this operation only through
the LMA and not via a SNMP management application like Transcend.
This feature lets you:
Back up your switch configuration in case of switch failure
■
Transfer the configuration from one switch to another
■
Maintain various standard configuration templates which can be
■
loaded according to requirement
The configuration upload works for individual cards installed in the
CoreBuilder 7000: either the active switch card or a CoreBuilder 7X00
Interface Card. You select the card whose configuration you want to
download or upload from a list of installed cards.
When the switch operates in single-IP mode, you can use this facility to
upload the configuration of any of the installed cards through the LMA of
the switch card. When the switch is operating in multiple-IP mode, you
can use this facility to upload the configuration of the switch card only.

Uploading Selected
Data Types
Organizing
Configuration Files
The CoreBuilder 7000 allows you to upload selected types of
configuration data. The types of configuration data you can upload
depends on the card you selected. For the switch card, the types of
configuration data you can upload are as follows:
All Configuration Data
■
Platform Parameters
■
ATM Addresses
■
PNNI Configuration
■
LANE Security
■
PVC Connections
■
LECS Topology
■
LECS Order List
■
For a CoreBuilder 7X00 card, the data types are as follows:
Platform Parameters
■
Static
■
The uploaded configuration files can be named using a naming
convention of your choice. Normally, you will want to include information
about the data type, the card type and a date or other identifier in the file
name. For example, you might use file names like cfg_7000_12jun98 and
static_7600_1.
When you download configuration data from the files on the disk to the
card, you designate the card by its slot number. The slot can contain the
original card from which the data was uploaded, or it can contain
another card of the same type.
If you try to download configuration data which was uploaded from one
type of card type to another type of card, an appropriate error message is
issued.

Activating the
Downloaded
Configuration
Uploading the
Configuration of a
Card
When the configuration files are downloaded into flash memory, they
overwrite the previous information. The new parameters are not
activated immediately, but rather after the next reboot when they are
read from the flash memory. The CoreBuilder 7000 assumes that the user
wants to reboot the switch as soon as possible to activate the new
configuration parameters. Therefore, subsequent to a configuration
download, all LMA and SNMP set operations are blocked until the next
reboot – except for the configuration upload/download and reboot
operations.
It is recommended, therefore, to perform a configuration download only
when you are ready to reboot and activate the new parameters.
Cards should not be “hot swapped” after a configuration download until
after the next reboot.
To store (upload) the configuration of a card installed in the CoreBuilder
chassis from flash memory to disk, first make sure that the switch is
connected to the TFTP server and that it is in single-IP mode and then
perform the following steps:
Perform the LMA menu command:

Connecting PNNI to E-IISP is done in two ways:
Using the 3.1 interface
■
Using the PNNI to IISP/E-IISP gateway
■
Connecting PNNI to E-IISP and IISP networks requires addressing to match
(use the same E.164 addressing scheme) in order to guarantee
uniqueness. This is necessary because PNNI works on the best match
routing scheme. The PNNI gateway function will advertise IISP and/or
E-IISP addresses as either native or as foreign reachability addresses.

ONFIGURING THE COREBUILDER
Migrating from E-IISP to PNNI
In order to migrate successfully to PNNI, the network manager must
review the network address scheme that will be used. There are two
possible approaches to implementing address change:
Deriving a PNNI peer group ID and peer group level based on the E-IISP
■
addressing scheme. See Chapter 3 in the Operations Guide for
information on E-IISP addressing.
Changing the E-IISP network prefixes to match the PNNI addressing

Load Sharing
The power supplies can operate in load-sharing mode; two 90A power
supplies can produce up to 180A. Providing that the power consumption
of the unit does not exceed 90 A, load-sharing allows one power supply
to serve as a backup.
Overloading
When the installed power supply is rated for less than the required power
consumption of the CoreBuilder module, the CoreBuilder will not
succeed in powering up. It will attempt to power up, hit the current
overload rate and turn the power supply off, going through this cycle
repeatedly until the load is reduced.
The power consumption of an entire CoreBuilder 7000 family ATM switch
unit is calculated by adding up the power consumption of the switching
card(s) and interface cards installed in the chassis. Normally, the values for
power consumption can be used in the calculation. Table 20

This section describes when redundant switch cards and redundant
power supplies can be used in a CoreBuilder switch.
In order to determine whether a redundant switch card and/or an
redundant power supply can be used in a CoreBuilder switch, the total
power consumption of all installed cards must be examined. According to
the total power consumption, there are three possibilities, as the
following examples illustrate:
Installation I:
The total power consumption of a single switching card
(that is, no redundant card installed) and all interface cards exceeds 90A.
In this case, a Dual 90A supply is required so that the second power
supply cannot be redundant. A redundant switch card can be installed.
This “heavy load” installation is illustrated by the first example installation
in Table 21.
Installation II:
The total power consumption of two
switching cards
(i.e., redundant card installed) and all interface cards exceeds 90A but
without the second switching card the consumption is less than 90A. In
this case, either a redundant switch card or a redundant power supply
can be installed, but not both. This “medium load” installation is
illustrated by the second example installation in Table 21.
Installation III:
The total power consumption of two switching cards
and all interface cards does not exceed 90A. In this case, both a
redundant switch card and a redundant power supply can be installed.
The light load installation is illustrated by the fourth example installation
in Table 21.
In all installations that do not include multiple CB7600 cards both
redundant switch cards and redundant power supplies can be installed.

The following problems may arise while working with the CoreBuilder®
7000 family ATM switch. If your problem does not appear on this list,
view relevant statistics and parameters using the Administration Console
menus (refer to the
). You can also contact 3Com Technical Support. Also, be sure to
Guide
read through the release notes.
If the control terminal is physically connected to the CoreBuilder 7000 family ATM switch,
but does not load the Administration Console Menus, verify that your terminal setup
matches the specifications (see “Connecting the Control Terminal” on page 46). Also,
make sure your cable is configured as DCE (see “Ethernet Cabling” on page 118).
If the cables attached to the CoreBuilder 7000 family ATM switch interface ports do not
work, check that the connectors are firmly snapped in place. Also, make sure that each
wire connects to Rx on one end and Tx on the other.
interface cards ACT LEDs should be blinking. If not, verify that the switch module and
interface cards are properly inserted. Make sure that the control terminal is connected to
the control port correctly, as an incorrect connection of this cable sometimes results in the
inability of the system to function properly.

Recommended Action for Common Problems (continued)
ProblemRecommended Action
Interface Card failsIf one of the interface cards fails, use the Initialize Interface (INI) option in the System (SYS)
menu, Interface (IFC) option to reinitialize the interface. If this fails, you can try to restart
the whole unit again. If neither of these actions correct the problem you should contact a
3Com service person.
When handling modules, always use a wrist strap that is connected to a proper ground.
This prevents the module from being damaged by electrostatic discharge.
Fans do not rotateIf the fans do not work when the unit is powered up, the fan tray may not be inserted
properly. Unplug the power cord and reinsert the fan tray properly against the enclosure.

Diagnostic Procedures
In case of system overheating, check that the power supply fan and the fans in the fan tray
are operating. To check for fan movement in the CoreBuilder 7000 family ATM switch’s
fan tray, pull a few modules from the chassis to view the fans on the left side of the
system.
*
Fiber optic transceivers are sensitive optical devices that need to be handled carefully. If dirt
collects on the fiber optic lens, you may notice that the LED for an ATM port link status
does not light. You may also notice degraded performance of that port, indicated by an
increase in the physical layer statistics count for that port.
To prevent dust from collecting on the fiber optic lens, keep the dust covers on the ports at
all times when they are not in use. To clean a fiber optic lens, follow the procedure below:
Remove any accumulated dust or debris from the port or connector by blowing off all
1
surfaces with a canned air duster.
Compressed gas is recommended, such as Chemtronics’ Ultrajet ® or the Triangle Tool
2
Group’s Liqui-Too!™ Dust-A-Way. Do not use commercial compressed air or “house
air” because of the risk of oil contamination.
Reconnect the cable to the port to see if the dusting corrected the problem.
3
If the LED still does not appear, or if it lights yellow, continue with steps 5 and 6.
4
Gently wipe the ports with a lint-free, non-abrasive, non-adhesive swab. Microswabs™
5
by Texwipe™ are recommended.
Gently wipe the connectors with a lint-free, non-abrasive wipe or pad. Texwipe™ pads
6
are recommended.
Safety Precautions for Fiber Optics Connectors
Avoid touching all surfaces after cleaning the connectors, and keep all
unused ports covered.
Vermeiden Sie das Berühren aller Oberflächen nach dem Säubern der
Kontakte und verdecken Sie alle nicht benutzten Öffnungen.
Ne toucher aucune surface après le nettoyage des connecteurs et garder
les pièces inutilisées couvertes.
