Installing the FC 4Gbps PCI-X Adapter

Attention: To avoid damage to your fiber-optic cables, follow these guidelines:

vDo not route the cable along a folding cable-management arm.

vFor 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.

vRoute the cable away from places where it can be damaged by other devices in the rack cabinet.

vDo not use plastic cable ties in place of the provided cable straps.

vDo 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.).

vDo not put excess weight on the cable at the connection point. Be sure that the cable is well supported.

vThe 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:

vDo 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.

vUse 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:
