IBM 74Y4064 User Manual

Voltage
3.3 V
Form factor
Short, full-height tailstock, low-prole capable
Cables
Use multimode ber optic cables with shortwave lasers that adhere to the following specications:
• OM3 or OM4: Multimode 50/125 micron ber, 2000 MHz x km bandwidth
• OM2: Multimode 50/125 micron ber, 500 MHz x km bandwidth
• OM1: Multimode 62.5/125 micron ber, 200 MHz x km bandwidth
Because core sizes are different, OM1 cables only can be connected to other OM1 cables. For best
results, OM2 cables must not be connected to OM3 or OM4 cables. However, if an OM2 cable is
connected to an OM3 or OM4 cable, the characteristics of the OM2 cable apply to the entire length of the
cables. The following table shows the supported distances for the different ber optic cable types at
different link speeds.

Adapter LED
Green and yellow LEDs can be seen through openings in the mounting bracket of the adapter. The green
LED indicates link activity and the yellow LED signies the link state. Table 45 on page 209 summarizes
the LED states for this adapter.

Operating system or partition requirements
If you are installing a new feature, ensure that you have the software that is required to support the new
feature and that you determine whether any prerequisites must be met for this feature and attaching
devices. For information about operating system and partition requirements, see one of the following
topics:
• The latest version of enabling libraries and utilities can be downloaded from Fix Central (http://
www.ibm.com/support/xcentral/).
• Power Systems Prerequisites (http://www14.software.ibm.com/support/customercare/iprt/home).
