ATTO Technology Inc. iPBridge Installation and Operation Manual
Appendix A Cabling
Additional information to physically connect ports to devices and to your SAN.
Fibre Channel connections
The Fibre Channel port connects the bridge into
either a Fabric or Arbitrated Loop.
The iPBridge 2700 uses optical SFP connectors
and multimode fiber optic cable.
Make sure all cables are anchored securely at both
ends with the proper connectors.
Ethernet connections
Use at least Cat 5e cable to connect the Ethernet
ports to your network.
Note
For best performance, all cabling, network
interface cards (NICs), host bus adapters
(HBAs), and network switches must be Gigabit
Ethernet (GbE), and at least Cat 5e certified.
Most standard offices use 2-pair wiring which
is not compatible. GbE requires 4-pair wiring.
For best performance, support for 9014 byte
jumbo frames should be available for all switches
and host iSCSI equipment.
Before you begin installing the iPBridge Ethernet
ports, be sure to check or complete the following:
• If you are managing your iSCSI system across a
WAN and your system uses a firewall, be sure
that the following ports are open and available:
If you are using the TCP protocol
• telnet (port 23)
• http (port 80)
• ftp (ports 20 and 21)
• iSCSI (port 3260)
• iSNS (port 3705)
If you are using the UDP protocol
• ntp (port 123)
• Be sure your host system(s) is set up and
configured.
• Your host system can use any of three
different types of cards: a network interface
card (NIC), a TCP/IP offload engine card
(TOE), or a storage network interface card
(SNIC).
• The ATTO driver file from the CD included
with your iPBridge or from the ATTO
website, www.attotech.com, is installed on
your host.
• The switch has been configured to forward
UDP broadcast messages.
• The minimum requirement for Windows-based
browsers is Internet Explorer 5.5 or Netscape
Navigator 6.2. The minimum requirement for
Macintosh browsers is Internet Explorer 5.2 or
Safari 1.2.
• Ethernet speed defaults to auto; the iPBridge will
determine the speed and set other parameters
based on the speed.
