FCC Radio Frequency Interference Statement

This equipment has been tested and found to comply with the limits for a Class B computing device, pursuant to Part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial

environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the

instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to

cause harmful interference in which the user will be required to correct the interference at his own expense.

Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.

The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits. This digital apparatus does not exceed the Class B

limits for radio noise emission from digital apparatus set out in the Radio Interference Regulation of the Canadian Department of

Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de classe B

prescrites dans le Règlement sur le brouillage radioélectrique publié par le ministère des Communications du Canada.

About the SNMP Management Module

The SNMP Management Module includes two twisted pair ports, one for
management and one reserved for future use. The Management Module
also features a DB-9 serial port. Both twisted pair ports include the
AutoCross feature that automatically selects between a crossover workstation
or straight-through, depending on the connected device.

An iMediaChassis series with an installed Management Module connects to
the LAN via an external 10/100 twisted pair connection. Connect the chassis
to the network by plugging one end of a CAT-5 twisted pair cable into the
port labeled MGMT on the Management Module. Plug the other end of the
cable into a device (e.g., switch, hub, etc.) in the existing Ethernet network.

Installing the Management Module

In order to manage an iMediaChassis series, available in 20, 6, or 3 slots, install the
SNMP Management Module. Slide the SNMP Management Module into the first
slot, on the far left of the chassis, using the card guides, and secure the module to the
chassis by tightening the captive screw. This slot is ONLY for the Management
Module; do not install Application Modules such as media conversion and mode
conversion modules in this slot.

Configuring

Once connected to a network, assign the SNMP Management Module IP
configuration information (e.g., IP address, subnet mask, etc.). There are four
ways to do this:

 Using iConfig
 Using the Management Module’s serial port
 Using DHCP (Dynamic Host Control Protocol); DHCP must be enabled

through serial configuration or Telnet, via iConfig

 Telnet (Default IP=10.10.10.10; subnet mask 255.0.0.0)

In addition to assigning an IP address and subnet mask, the iMediaChassis
series also allows creation of community strings, assigning access rights,
configuration of traps and more. iConfig offers more options than configuring
via the serial port or Telnet. After assigning the iMediaChassis series an IP
address, use iView² or another SNMP compatible Network Management
System (NMS) to remotely configure, monitor and manage the modules
installed.

SNMP Write Lock (iMediaChassis series)

There is an SNMP Write Lock switch on the iMediaChassis series; check the
specific iMediaChassis manual for the location. The SNMP Write Lock
switch prevents a new Management Module from re-configuring an iMcV­application module’s settings (e.g. the status of features such as LinkLoss,
FiberAlert, Force mode, etc.) made via SNMP on any previous management
board (s).

NOTE

Leave this switch in the
position should only be used when changing the SNMP Management Module.

NORMAL

position during day-to-day operation; the

LOCKED

As stated, SNMP Management Modules can be removed and replaced as
necessary. A saved PROM file can be downloaded to the second SNMP
module to retain configuration settings.

Make sure the SNMP Write Lock switch is set to the LOCKED position. The
PROM file should be saved periodically in case there is a need to replace the
SNMP Management Module.

Saving the existing PROM creates a back-up file which can be used in the
event that a unit or PROM update fails. It is recommended that the PROM
be saved after the user is satisfied with his current configuration settings, as
saving the PROM at this point will allow them to recover their configurations
as well.

3

1. Open a session in iConfig with a device you want to administer.

2. Choose the Administration tab.

3. Click the Save PROM File button.

4. The Save as PROM dialog box appears.

5. Choose a folder and then select the filename you wish to save.

NOTE

.BIN is the default extension.

6. Click the Save button to save, the file is saved.

7. Add entries to the Notes box, if desired; then click OK. If you do not

wish to enter Notes, click Close.

8. Click OK to close Succeeded dialog box. (Prom Save was successful.)

If the Management Module is removed with the SNMP Write Lock switch set
to NORMAL, all module revert to their hardware settings by default; for any
module with on-board logic, refer to its manual for details. Hardware
settings should be configured to match those made via SNMP. Always
reconfigure application modules when moving them from one chassis’ slot to
another.

Using the SNMP Write Lock Switch

1. Ensure the SNMP Write Lock switch is set to NORMAL.

2. After configuring all application module settings via SNMP, use the

iConfig application to make a backup copy of the SNMP management
board’s firmware.

3. If the SNMP Management Module needs to be replaced, set the SNMP

Write Lock switch to LOCKED.

4. Remove the old SNMP module and replace with another SNMP

module.

5. Connect to this SNMP module via iView² and then launch iConfig.

Select the Administration tab and click on List Tasks. Highlight Flashsav
and then click on the Terminate button.

6. Update the new board with the firmware backup made in Step 2.

7. Reboot the SNMP Management Module with the reboot command to

enable changes.

4

8. After rebooting, set the SNMP Write Lock switch back to NORMAL. The

previously made settings to the application modules will be active.

NOTE

When removing an SNMP card with the SNMP Write Lock enabled (set to LOCKED),
current application modules settings will not be changed. Never power-cycle the chassis
while the SNMP Write Lock is enabled (except during Step 5 in the preceding process).
This will revert the SNMP card back to its original factory settings. (iView² should only be
accessed with the SNMP Write Lock disabled.)

Using Telnet

The iMediaChassis series supports Telnet for remote configuration. All
configurations that can be performed via the serial port can also be
performed using Telnet (except serial passwords). Use only one Telnet
session at a time. Do not use an RS-232 serial session and a Telnet session at
the same time.

About DHCP

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 iConfig, an RS-232 Serial session, or Telnet.
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 dialog 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 the

About Serial Port Configuration

for more information about
Enabling/Disabling DHCP. When there is no DHCP server on the network, use
iConfig or serial configuration to manually set the IP addresses.

When DHCP is enabled, the IP address (default 10.10.10.10 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.
