Statement
This document is a guide to simple and convenient hardware installation. Please read it carefully before installation, to
prevent bodily injury or device damage.
The device installation personnel must be well trained before installation, to master correct installation operations and safety
precautions.
Device installation shall follow local safety regulations. Precautions listed in this document are suppliments to local safety
regulartions. Raisecom shall not be reliable to any accident if common safety operation requirements are violated, or design,
manufacturing, or usage security standards for devices are violated.
Lightning safety
Device installation is prohabited in lightning and thunderstorm conditions to prevent bodily injury and device damage.
High-voltage safety
DO NOT install or remove the device when it is powered on, to prevent unpredictable bodily injury.
Use special tools instead of common tools when conducting operations in high voltage and AC power conditions.
Prevent the device from being rotted. Once the device is rotted, power off it immediately.
Electrostatic discharge safety
Any time when contacting the device, you must wear an Electro-Static Discharge (ESD) wrist strap in good contact with skin
and have the other end of the ESD wrist grounded.
Grounding safety
Before connecting cables, ensure that the device is fixed and is well grounded. Do not connect other cables if the device is
not grounded.
Laser safety
Before cutting or welding fiber, disconnect the fiber and the optical source. DO NOT stare into the optical interface to
prevent eye injury.

Power supply
conditions
The maximum overall power consumption is 300 W, so the power supply module must provide
power above this. We recommend providing a backup power supply, which can ensure that the
device runs properly when the power supply fails.
DC power supply:
Rated voltage: -48 V
Voltage range: - 40 to -57 V
ESD protection
Use effective ESD measures. The absolute value of the static voltage must be smaller than
1000 V.
Grounding condition
The device should adopt joint grounding mode, with a grounding resistance smaller than 1 Ω.
Installation tools
Diagonal pliers, cold compression pincers, flathead screwdriver, Philips screwdriver,
adjustable spanner, open-end spanner, Allen wrench, wire stripper, crimping pliers, tape
measure, level meter, crystal head crimping pliers, electric soldering iron, ESD glove, ESD
wrist, insulation tape, multimeter, optical power meter, OAMS, ground resistance tester, and
cable tester

Installing device on cabinet
Push the chassis into the cabinet slowly.
Fix the chassis to the cabinet with screws.
Installing fan
Stably insert the fan into
the chassis along the guiderail
unless the right ejector lever
mates with the baffle on the
groove of the chassis, and then
push the fan into the groove.
Pivot ejector levers and
then push the fan inward by
holding the handles to make
the fan fully inserted into the
chassis. Release ejector levers
to make them mated with the
chassis tightly.
Installing cards
Confirm the slot into which the card is
inserted. Then, remove the blank panel.
Stably insert the card into the chassis
along the guiderail.

4
Pivot ejector levers outward at a slight 45-degree angle to make ejector levers engaged with frames of the chassis. (No
figure)
Pivot ejector levers inward to make the
card fully inserted into the chassis.
Tighten captive screws.
Installing power supply
Power cards are inserted into the left 2 slots of the chassis. There is a spring ejector lever on the front panel of the power card.
Steps for installing the power card are identical to the ones for installing the fan.

Connect the grounding cable.
Connect the other end of the grounding cable to the
grounding terminal of the cabinet or the grounding bar in the
equipment room.
2 Connecting Ethernet cable
Make the Ethernet cable. For details, see iTN8800 Hardware Description.
Align the header of the Ethernet cable with the Ethernet interface of the
device, and insert it properly.
3 Connecting fiber
Inserting SC/PC fiber into SFP optical interface
Insert the SFP optical module into the optical interface
on the device.
Remove the dustproof cap from the optical module and
fiber connector respectively, align the header of fiber
connector with the interface on the SFP optical module, and
insert it properly.
Inserting LC/PC fiber into XFP optical interface
Insert the XFP optical module into the optical interface
on the device.

Use the optical power meter to measure the Tx optical power (P1) of the installed SFP optical
module. Compare P1 with the metric of the SFP optical module to confirm whether the SFP
optical module works properly.
Use a
multimeter.

Connect the ODF-side fiber, which is connected to the device, to the optical power meter and
measure the optical power (P2). Compare P2 with P1. If difference between P2 and P1 is smaller
than 1 dB, it indicates that the fiber is connected properly.
