Step 8
Power up the host and peripheral equipment. At this point, there must be no
external power supplies plugged into the M4-200 upstream or downstream
boxes,
Step 9
Observe the Power Light Emitting Diode on the side of the boxes.
If the upstream box LED is illuminated, no external power supply is
required.
Likewise if the downstream box LED is illuminated, no external power
supply is required.
Step 10
If both Power LEDs are illuminated, then the Firewire link is active. Proceed
with the software bring-up on the host system. Ignore further steps
Step 11
If one or both of the upstream/downstream Power LEDs are dark, then power
down all equipment and plug in one or two Opticis power supplies.
Step 12
Power up complete system. Both upstream/downstream LEDs should be
illuminated. Proceed with host software bring-up.
Do NOT plug in external power to the box if the PWR LED is on
after the M4-200 repeater is connected to a live host or powered peripheral.
1-4 Installation (continued)
Installation
Important: Please use the installation procedure below. Improper, or no
operation may result if the start-up sequence is not correctly followed.
Step 1
Carefully unpack the contents of the shipping group.
Step 2
Ensure no
host or peripheral equipment is powered up.
Step 3
The M4-200 Firewire repeater boxes are identical. Identify one as upstream
(or host) and downstream (or peripheral).
Step 4
Prepare a duplex LC patch cord fiber-optic cable (Multi-Mode Glass Optical
Fiber with 62.5/125 µm or 50.0/125 µm core). Attach the two LC connector
fiber cables first
with no power applied to any system component as follows:
Tx (Upstream) to Rx (Downstream)
Rx (Upstream) to Tx (Downstream)

Step 5
Connect the upstream box to the host computer using a copper Firewire cable
by plugging into the host computer Firewire card and the upstream box
Firewire port (either one)
Step 6
Connect the downstream box to the peripheral equipment in a similar manner.
Step 7
If there are non-Opticis external power supplies to be attached, do so now.
e.g. block power supplies for laptop Firewire PC cards, downstream
appliances, etc. Do NOT
attach the Opticis power supplies until instructed to
do so.
