Safety recommendations
To avoid any equipment damage or bodily injury caused by improper use, read the following safety
recommendations before installation. Note that the recommendations do not cover every possible
hazardous condition.
Safety symbols
When reading this document, note the following symbols:
WARNING means an alert that calls attention to important information that if not understood or
followed can result in personal injury.
CAUTION means an alert that calls attention to important information that if not understood or
followed can result in data loss, data corruption, or damage to hardware or software.
General safety recommendations
•
Keep the chassis and installation tools away from walk areas.
•
Make sure the ground is dry and flat and anti-slip measures are in place.
•
Unplug all the external cables (including power cords) before moving the chassis.
Electricity safety
•
Locate the emergency power-off switch in the room before installation. Shut the power off at
once in case accident occurs.
•
Make sure the router has been reliably grounded.
•
Do not open or close the chassis cover when the router is powered on.
•
Use an uninterrupted power supply (UPS).
•
If there are two power inputs, disconnect the two power inputs to power off the router.
•
Do not work alone when the router has power.
•
Always verify that the power has been disconnected.

2
Laser safety
WARNING
!
•
The router is a Class 1 laser device.
•
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.
Router moving
CAUTION:
Do not hold the handle of the fan tray
or power supply, the handle on the rear
cover of the chassis, or
the air vents of chassis
to move the router. Doing so might
cause equipment damage or even bodily
injury.
When moving the router, follow these guidelines:
•
When moving the router, hold the handles at both sides of the chassis.
•
Use at least two people to move the router.
•
Move the router carefully.
Examining the installation site
The router can be used only indoors. For the router to operate correctly and to have a long service
lifetime, make sure the installation site meets the requirements described in the following
subsections.
Weight support
Make sure the floor can support the total weight of the router and accessories (such as the rack and
interface modules). For the weights of the router and accessories, see H3C SR6604[6608] Routers
Hardware Information and Specifications.
Temperature
If the temperature in the equipment room is too high, too low, or changes dramatically, the router
reliability will be reduced and its service lifetime will be shortened. For long-term, highly available
operation of the router, make sure temperature in the equipment room meets the requirements
described in Table1-2.
Table1-2 Temperature requirements
Item
Temperature
Operating Temperature 0°C to 45°C (32°F to 113°F)
Storage Temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table1-3.
