To pass a fiber through a metallic board hole, make sure the fiber has protective covering and
the hole has a smooth and fully filleted surface. (The filleting radius must be not less than 2 mm,
or 0.08 in.)
•
To bend a fiber along the acute side of mechanical parts, make sure the fiber has protective
covering..
Moving the router
WARNING!
Do not hold the handle of a fan tray or power supply, the handle of the rear cover of the chassis, or
the air vents of chassis, to move the router. Any attempt to carry the router with these parts might
cause equipment damage or bodily injury.
When you move a router, follow these guidelines:
•
Lift and put down the chassis slowly and do not move it suddenly.
•
When you move a heavy router or multiple routers, use a pallet jack.
•
Before moving the router, 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 the 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 when moving the router.
•
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:
Check the resistance of the ESD wrist strap for safety. The resistance reading should be in the range
of 1 to 10 megohm (Mohm) between a human body and the ground.
To prevent electrostatic discharge (ESD), follow these guidelines:
•
Make sure the router and the rack are reliably grounded.
•
Make sure an anti-static floor is installed and reliably grounded.
•
Keep the equipment room clean to reduce the negative effects of dusts and particles.
•
Maintain the humidity and temperature levels 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 with the electronic components facing upward on an
antistatic workbench, or put it into an antistatic bag.
•
Touch only the edges when you observe or move a removed CF card or LPU. Do not touch the
electronic components.
To attach an ESD wrist strap:
1.
Wear the wrist strap on your wrist.
2.
Lock the wrist strap tight around your wrist to keep good contact with the skin.
