Handling fiber-optic cables
Before you use fiber-optic cables, read the following precautions.
Attention:
To avoid damage to the fiber-optic cables, follow these guidelines:
v
Do not route the cable along a folding cable-management arm.
v
When attaching to a device on slide rails, leave enough slack in the cable so that
it does not bend to a radius of less than 38 mm (1.5 in.) when extended or
become pinched when retracted.
v
Route the cable away from places where it can be snagged by other devices in
the rack cabinet.
v
Do not overtighten the cable straps or bend the cables to a radius of less than 38
mm (1.5 in.).
v
Do not put excess weight on the cable at the connection point. Be sure that the
cable is well supported.
CAUTION:
Data processing environments can contain equipment transmitting on system
links with laser modules that operate at greater than Class 1 power levels.
For this reason, never look into the end of an optical fiber cable or open
receptacle.
Fire suppression systems
A fire suppression system is the responsibility of the customer. The customer's own
insurance underwriter, local fire marshal, or a local building inspector, or both,
should be consulted in selecting a fire suppression system that provides the correct
level of coverage and protection.
IBM designs and manufactures equipment to internal and external standards that
require certain environments for reliable operation. Because IBM does not test any
equipment for compatibility with fire suppression systems, IBM does not make
compatibility claims of any kind nor does IBM provide recommendations on fire
suppression systems.
