• Before connecting an optical fiber, use dust free paper and absolute alcohol to clean the end face
of the two fiber connectors. You can brush the end faces only in one direction.
• After a fiber is installed well, the bend radius must be not less than 10 cm (3.94 in).
• If the fiber has to pass through a metallic board hole, the hole must have a sleek and fully filleted
surface. (The filleting radius must be not less than 2 mm, or 0.08 in.) When passing through a
metallic board hole or bending along the acute side of mechanical parts, the fiber must wear
jackets or cushions.
Router moving
CAUTION:
Do not hold the handle of the fan tray or power supply, the handle of the rear cover of the chassis, or the
air vents of chassis. Any attempt to carry the router with these parts might cause equipment damage or
even bodily injury.
When you move a router, follow these guidelines:
• Lift and put down the chassis slowly and never move suddenly.
• When you move a heavy router or multiple routers, use a pallet jack.
• Before moving the chassis, turn off the power switch and remove all cables, USB devices, and
mounting brackets.
• If the router needs to be moved over a long distance, remove all field replacement units (FRUs), such
as HIMs/MIMs, put them separately in anti-static bags, and install the filler panels supplied with
router.
• If the router needs to be moved over a short distance, make sure all FRUs are securely seated in slots
and the screws are fastened.
• Make sure the accessories of the router are not lost or damaged during router moving.
• Make sure the ground is dry and flat and anti-slip measures are in place.
• Keep the chassis and installation tools away from walk areas.
ESD prevention
CAUTION:
Make sure the resistance reading between human body and the ground is in the range of 1 to 10 megohm
(Mohm).
To prevent electrostatic discharge (ESD), follow these guidelines:
• Make sure the router and the rack are well grounded.
• An anti-static floor is installed and well grounded.
• Take dust-proof measures for the equipment room.
• Maintain the humidity and temperature in the acceptable range.
• Always wear an ESD wrist strap and ESD cloth when touching a circuit board or transceiver module.
• Place the removed CF card or LPU on an antistatic workbench, with the face upward, or put it into
an antistatic bag.
