5.2.2.2Virtual media restrictions

The following list specifies restrictions for using virtual media:

•The KVM s3-1621 and KVM s3-1641 virtual media appliances support only the connection of USB 2.0 diskette drives, Flash drives, and CD drives.

•The KVM s3 Client supports only mapping of USB 2.0 and USB 1.1 diskette drives and Flash drives connected to the client computer.

5.3UTP cabling

The following information is intended to brief you on various aspects of connection media. The performance of a switching system depends on high quality connections. Poor quality or poorly installed or maintained cabling can diminish system performance.This appendix is for information purposes only. Consult with the local code officials or cabling consultants prior to any installation.

5.3.1UTP copper cabling

Switching systems use unshielded twisted pair (UTP) cabling.The following are basic definitions for the three types of UTP cabling that the KVM s3-1621 and KVM s3-1641 appliances support:

•Cat 5 UTP (4-pair) high performance cable consists of twisted pair conductors, used primarily for data transmission. The twisting of the pairs gives this cable some immunity from the infiltration of unwanted interference. Cat 5 cable is generally used for networks running at 100 or 1000 Mbps.

•Cat 5E (enhanced) cable has the same characteristics as Cat 5, but is manufactured to somewhat more stringent standards.

•Cat 6 cable is manufactured to tighter requirements than Cat 5E cable. Cat 6 has higher measured frequency ranges and significantly better performance requirements than Cat 5E cable at the same frequencies.
