Installing Modules
Refer to the installation guide shipped with the
SNMP Module
for configu-
ration information. To install a module, remove the blank bracket (if present)
covering the slot where you’ll be installing the module. Slide the module into
the chassis using the card guides, then secure the module to the chassis by
tightening the captive screw.
Installing a module into an 8-Slot Chassis
Connecting a Managed Media Converter System II
A
Media Converter System II
chassis with management enabled (discussed
below) connects to the LAN via an external 10Base-T connection. Connect
the chassis to the network by plugging one end of a CAT-5 straight-through
twisted pair cable into the port labeled “SNMP” on the
Media Converter
System II
chassis. Plug the other end of the cable into a device (e.g., switch,
hub, etc.) in your existing 10 Mbps Ethernet network. The management port
always operates in half-duplex mode.
Configuring Media Converter System II
Once connected to the LAN, a
Media Converter System II
chassis must
have its SNMP agent enabled in order to allow for SNMP management. Do
this by moving the switch labeled “SNMP” to the “ON” position. The
“SNMP” LED will then glow green, indicating that the SNMP agent has been
enabled. Next, assign the chassis IP configuration information (e.g., IP
address, subnet mask, etc.). There are three ways to do this:
•
Using DHCP (
Dynamic Host Control Protocol
)
•
Using

Fiber Optic transmitters and receivers are extremely susceptible to contamina-
tion by particles of dirt or dust which can obstruct the optic path and cause per-
formance degradation. Good system performance requires clean optics and con-
nector 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 by the manufacturer to ensure factory-clean optical
devices. These protective caps should not be removed until the moment of
connecting the fiber cable to the device. Assure that the fiber is properly ter-
minated, polished and free of any dust or dirt and that the location is as free
from dust and dirt as possible.
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) Should it be necessary to disconnect the fiber device, reinstall the protective
dust caps.
5) 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.

Electrostatic discharge (ESD) can cause damage to your add-in modules. Always
observe the following precautions when installing or handling an add-in module or
any board assembly.
1) Do not remove unit from its protective packaging until you’re ready to install
it.
2) Wear an ESD wrist grounding strap before handling any module or compo-
nent. If you do not have a wrist strap, maintain grounded contact with the
system unit throughout any procedure requiring ESD protection.
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.
3) Hold boards by the edges only; 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 board over any surface.

The following precautions should be observed when installing chassis with
DC power supplies.
1) Check nameplate ratings to assure there is no overloading of supply circuits
that could have an effect on overcurrent protection and supply wiring.
2) When installing 48V DC rated equipment, it must be installed only per the
following conditions:
