4.7 Modular Optical Transceiver Installation
The
modular
optical
transceivers
are
available
separately
and
may
or
may
not
be
installed
in
the
DHU
depending
on
the
configuration
ordered.
If
the
optical
transceivers
are
factory
installed
in
the
DHU,
skip
this
section
and
proceed
to
Section
4.8.
If
the
optical
transceivers
are
not
factory
installed,
use
the
following
procedure
to
install
each
transceiver:
1.
Slip
on
an
Electro-Static
Discharge
(ESD)
wrist
strap
and
connect
the
ground
wire
to
an
earth
ground
source
such
as
the
grounding
stud
on
the
DHU
front
panel.
Wear
the
ESD
wrist
strap
while
completing
the
optical
transceiver
installation
procedure.
Warning:
Electronic
components
can
be
damaged
by
static
electrical
discharge.
To
prevent
ESD
damage,
always
wear
an
ESD
wrist
strap
when
handling
electronic
components.
2.
Locate
the
appropriate
transceiver
socket
on
the
front
of
the
DHU
as
shown
in
Figure
18.

Select
the
optical
transceiver
that
corresponds
to
the
type
of
fiber
(single-
or
multi-mode)
required
for
the
installation.
The
color
of
the
transceiver
(see
transceiver
color
code
in
Figure

corresponds
to
the
fiber
type.
4.
Remove
the
transceiver
from
the
anti-static
packaging
and
orient
for
installation
(see
Figure
18.).
Note:
Two
types
of
optical
transceivers,
type
A
and
type
B,
are
available.
Both
types
provide
the
same
functionality.
On
the
type
A
optical
transceiver,
the
release
lever
(see
Figure

must
be
closed
for
installation.
