About the iMediaChassis/3

The iMediaChassis/3 is a modular chassis platform design ed for use wit h the IM C
Networks SNMP-manageable series o f m odul e s (iMc V). Th e iMedi aC has sis/ 3 fea tures
three slots for installing application series modules plus an additional slot for installing
an SNMP management module. The inclu de d SNMP L ock f eature al lo ws th e
management slot to save SNMP settings while the management module is removed.

The iMediaChassis/3 can also hold two double wide “iMcV” modules, when there is
no SNMP management card in the management slot. Double-wide modules with
built-in management, such as the iMcV-Giga-FiberLinX-II, can be managed in the
chassis without the need for an SNMP module in the management slot.

The power supply configurations available for the iMediaChassis/3 include the
following:

•

Single AC

Installing the iMediaChassis/3

Specifications

Before installing the application modules into an iMediaChassis/3, install the chassis
first. When installing the chassis, be sure to observe the following precautions to
prevent electrical or mechanic al damage:

•

Stay within the chassis power rating to prevent overload of supply circuits or
damage to overcurrent prot ection and supply wiring.

•

Maintain reliable earth ground, especially when connecting to a power strip
instead of directly to a branch circuit.

•

Protect the chassis from exposure to sunlight and electrical or magnetic fields.

Fault-Tolerant Power

The fault-tolerant powering option applies to units utiliz ing two power su ppl ies. If
failure occurs on one power supply, the other supply takes over in its place and
carries the power load. Refer to the

Power Supply

and

Temperature Control

sections

for wiring, alarm, and Trap information.

NOTE

The iMediaChassis/3 power s upp ly is not fie ld repl ace a ble.

Installing Application Modules

Refer to the module installation guide for configuration information. To install a
module, remove the f aceplate (if present) covering the slot where the module will be
installed. Double-wide modules will occupy two slots. Slide the module into the
chassis using the card guides, and secure the module to the chassis by tightening the
captive screw. Each module slot provides 1.5 Amps. The management slot uses a
connector that is longer than slots 1-3 and should only be used for installing the
management module.

Alarm Reset

t

Installing Management Modules

This feature is available on the fault-tolerant (dual-power supply) model of the
iMediaChassis/3. When one power supply malfunctions, an alarm will sound. A red
alarm reset button, located next to the power connector on the right side of the
power supply, stops this alarm. The LEDs on the mana g e men t m o dul e and t he
iView² software both display power supply failures. If a power supply failure occurs,
return the iMediaChassis/3 to IMC Networks for repair or replacement.

Last Gasp Alarm

The iMediaChassis/3 includes the Last Gas p fe atur e, whic h s en ds a Trap whe n the
following occurs:

•

Both power supplies malfunction,

•

Both power supplies are powered down

•

When the AC line fails

Temperature Control

The iMediaChassis/3 includes temperature activated fans and an SNMP temperature
Trap to protect the chassis from over h ea ting.

Temperature Triggered Fans

The iMediaChassis/3 incl udes temperature triggered fans. When the temperature of
the chassis reaches 40° C, the two fans are activated. You can test the fans operation
by holding the Alarm Reset button down for 4 to 5 seconds. The fans will activate
and then they will turn off when you release the button. If the fans do not activate,
contact IMC Networks.

Temperature SNMP Trap

The management module includes a heat sensor for monitoring the temperature of
the iMediaChassis/3. You can define a threshold for chassis temperature by using
SNMP (refer to the iView² online help for more information about assigning Traps).
When the temperature of the chassis rises above the specified level, the SNMP agent
sends a Trap to the administrator. There is also an LED indicator on the SNMP
Management Module for module temperature (refer to the

Module LEDs

section for more information).

SNMP Management

Slot 1 Slot 2

Management Slo

Slot 3

An SNMP Management Module must be installed in the iMediaChassis/3 to enable
module and chassis management (except when using modules with built-in
management, such as the iMcV-Giga-FiberLinX-II). The SNMP Management module
installs in the management slot located at the bottom left of the chassis. This slot is
only for the management module; do not install application modules such as media
conversion and mode conversion modules in this slot. Double wide modules
installed in Slot 1 will overlap the management slot.

NOTE

The SNMP Management module includes DIP switches. These switches are
factory set and must not be moved.

SNMP Management Module LEDs

Each SNMP Management Module features several LEDs.
The LED functions are:

•

LNK/ACT

Glows green when a link is established on port.
Blinks green when data activity occurs.

•

FDX/COL:

Glows amber when port is in Full-Duplex mode.
Blinks amber when port is operating in Half-Duplex mode and
collisions occur.

•

TEMP:

Glows amber when temperature of unit sur pas s es a user- def in ed
level.

•

Connecting Chassis and Modules

When Not Using iView²

An iMediaChassis/3 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 t he port labele d

MGMT

on the
management card, or the management-enabled application card. Plug the other end
of the cable into a device (e.g., switch, hub, etc.) in an existing Ethernet network.
The port labeled

OPTION

is reserved for future use. Both twisted pair ports include
the AutoCross feature. This feature automatically enables either a crossover or a
straight-through connection, depending on the connected devi ce.

Configuring an SNMP-Management Card

Once connected to the LAN, assign the iMediaChassis/3 IP configuration information
(e.g., IP address, subnet mask, etc.).

You can assign the IP information by using one of the following:

•

iConfig

•

The management module serial port

•

DHCP (Dynamic Host Control Protocol); DHCP must be enabled through serial
configuration

You can also create community strings, assign access rights, configure Traps and
more. Using iConfig allows more Trap and MIB access configuration options than
when using the serial port.

After assigning the iMediaChassis/3 an IP address, use iView² or another SNMP­compatible Network Management System (NMS) to remotely configure, monitor and
manage the modules installed within the unit.

When using an application other than iView² for management, integrate the SNMP
vendor files (a.k.a. MIBs) into the application. The SNMP agent uses the following
Enterprise-specific MIB file and standard MIBs, which can be fo und in the MIB
directory on the CD included with the iMediaChassis/3: MCIMCV2C.MIB Enterprise­specific information for the agent. For example, configuration information, port type
information, link status, etc.

Using the MCIMCV2C.MIB

Refer to the management software documentation for information on how MIB files
are integrated into the software.

Power Supply

The iMediaChassis/3 ships with on e or tw o AC or DC pow er su ppli es, or one of each,
depending on the model.

DC Power Supply Wiring Instructions

The following image shows the wiring configuration for a Telco application of -48
VDC power supply for the iMediaChassis/3.

SNMP Write Lock

There is an SNMP Write Lock switch loc at e d o n the bac k of
the iMediaChassis/3. The SNMP Write Lock switch prevents
a new management board from re-configuring the
application module settings (like the status of features such as
LinkLoss, FiberAlert, Force mode, etc.) made by SNMP an d hel d on the pr evious
management board.

4

NOTE

Incorrect wiring will result in chassis malfunction.
The iMediaChassis/3 is compliant with Isolated Grounding Plane practices. The

POSITIVE and NEGATIVE terminals are isolated from chassis ground and must have a
ground reference at the power-sourcing equipment.

). All of the configurations that are available

Assigning IP

from the serial port are also available from Teln et. Use onl y o ne Telnet session at a
time. Do not use an RS-232 se rial session and a Telnet session at the same time.

NOTE

A Telnet session uses the same password as the iConfig application.

About DHCP

There is a DHCP client in the SNMP Management Card. By default, the DHCP client
is disabled. If a DHCP server is present on the net w or k and D HC P is ena bled, 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 iMediaChassis/3 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 DHC P server on the network, use
iConfig or serial configuration to manually set the IP addresses.

When DHCP is enabled, the IP addres s (d efault 10.10.10.10 or user configured) is
saved. When DHCP is disabled, the saved IP ad dress will be reinstated and the
device will reboot.

Enabling/Disabling DHCP

iConfig is a configuration utility (part of iView²) that lets users quickly and easily
complete the first stages of SNMP configuration for SNMP-manageable devices.
iConfig can set the IP address, subnet mask and default gateway as well as define the
SNMP community strings and Traps.

In addition to the above functions, iConfig offers an authorized IP address system and
access restriction to MIB groups supported by manageable devices. These extra
layers of security are purely optional and do not affect SNMP compatibility in any
way.

The iConfig utility can also be used to upload new versions of the system software. It
also offers diagnostic capabilities for faster resolution of technical support issues.

The default user ID for both iConfig and Telnet is:

•

User:

admin

•

Password:

admin

The iConfig utility works with the Windows 98, Windows NT, Windows 2000, and
Windows XP operating systems.

The iConfig utility is available as a standalone application as well as built in to the
Windows version of iView² (Windows 98 users must use the standalone version of the
iConfig utility). Both applications are included on the iView² CD. Refer to the
iConfig utility online help file for more information about the iConfig utility.

To Enable/Disable DHCP, press D. Then, type

About Serial Port Configuration

The SNMP management module used with the iMediaChassis/3 features a serial port
that includes an IBM-compatible DB-9 serial connector. To connect an
iMediaChassis/3 to a computer, use a straight­through (pin-to-pin) cable. (When the computer
has a serial port using a connection not
compatible with a DB-9 COM port, use the pin
connection chart for reference in making a cable.)
Make sure the cable length is less than 50 ft.
(15.24 m). Plug one end of the cable into the
DB-9 connector on the iMediaChassis/3 and the
