Laser Safety; Moving Safety - H3C CR19000-20 Installation Manual

Preventing electrostatic discharge
To prevent electrostatic discharge (ESD) damage, follow these guidelines:
•
Ground the router reliably. For how to ground your router, see "Grounding the router."
•
Always wear an ESD clothing, an ESD wrist strap, and ESD gloves when installing or removing
removable components. Make sure the wrist strap is reliably grounded.
•
Hold a module by its edges. Do not touch any electronic components or PCB.
•
Put a module in an antistatic bag and keep it secure if you are not to install it in the chassis.
Attaching an ESD wrist strap
1. Put the wrist band of the ESD wrist strap on your wrist.
2. Lock the wrist band tight around your wrist so that it makes good contact with the skin.
3. Attach the other end of the ESD wrist strap to an ESD jack on the chassis.
The router has one ESD jack on both the front and rear panel.
4. Make sure the rack and router is reliably grounded.

Laser safety

WARNING!
• Disconnected optical fibers or transceiver modules might emit invisible laser light. Do not stare
into beams or view directly with optical instruments when the router is operating.
• Before you remove the optical fiber connector from a fiber port, execute the
command in interface view to shut down the port.
CAUTION:
• Insert dust caps into open optical fiber connectors to protect them from contamination and ESD
damage.
• Insert dust plugs into open fiber ports and transceiver module ports to protect them from
contamination and ESD damage.

Moving safety

WARNING!
Hold the chassis handles firmly to move the router.
CAUTION:
Do not hold air vents of the chassis or the handle of a fan tray, power supply, or module to move the
router. Doing so might cause equipment damage.
The router is heavy and large. When you move the router, follow these guidelines:
•
Before unpacking the router, use a mechanical device such as a forklift to move the router as a
best practice. After unpacking the router, use the dolly provided with the router to move the
router to the installation location.
•
Remove all power supplies, modules, and external cables (including power cords) before
moving the chassis.
•
To move the chassis manually, you need four to five people. Before moving the router, remove
modules, filler panels, and fan trays from the router.
•
Lift and put down the chassis slowly and never move it suddenly.
