Installing the FC 4Gbps PCI-X Adapter
Attention: To avoid damage to your fiber-optic cables, follow these guidelines:
v Do not route the cable along a folding cable-management arm.
v For devices on slide rails, leave enough slack in the cables so that they do not
bend to a diameter of less than 76 mm (3 in.) or to a radius 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 damaged by other devices in
the rack cabinet.
v Do not use plastic cable ties in place of the provided cable straps.
v Do not overtighten the cable straps or bend the cables to a diameter of less than
76 mm (3 in.) or a radius 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.
v The following are the recommended maximum cable lengths.
– 1Gbps: 500 meters 50/125 µm fiber, 300 meters 62.5/125 µm fiber
– 2Gbps: 300 meters 50/125 µm fiber, 150 meters 62.5/125 µm fiber
– 4Gbps: 150 meters 50/125 µm fiber, 70 meters 62.5/125 µm fiber
CAUTION:
When laser products (such as CD-ROMs, DVD drives, fiber optic devices, or
transmitters) are installed, note the following:
v Do not remove the covers. Removing the covers of the laser product could
result in exposure to hazardous laser radiation. There are no serviceable
parts inside the device.
v Use of controls or adjustments or performance of procedures other than
those specified herein might result in hazardous radiation exposure.
DANGER
Some
laser products contain an embedded Class 3A or Class 3B laser
diode. Note the following.
Laser radiation when open. Do not stare into the beam, do not view directly
with optical instruments, and avoid direct exposure to the beam.
The FC 4Gbps PCI-X Adapter comes with an attached standard 3U adapter bracket
as shown in Figure 2 on page 4. An additional Low Profile 2U bracket also comes
with the adapter. Before you install the FC 4Gbps PCI-X Adapter, verify whether you
need the Fibre Channel Low Profile 2U adapter bracket. If you need to install the
Low Profile 2U bracket, continue with step 1. Otherwise, go to step 2.
1. Complete the following steps to install the Fibre Channel Low Profile 2U
adapter bracket:
