1 Chapter 1 Introducing the HP P4459A 8-Port Fibre Loop Switch The following sections of this chapter provide an overview of the features and functions of the fibre loop switch: • Fibre Loop Switch Features • Switching Operation Fibre Lo op Switch Features The fibre loop switch features an integra l 12Gb/sec.
2 HP P445 9A 8-Port Fi bre Loop Switch In stallati on & Opera tion Gui de Figure 1: Front V iew of the Fibre Loop Switch Front Pa nel L EDs In addition to the port connectors, the front panel of the fibre loop switch contains LEDs that provide diagnostic information for both switch and port status, and an IEC power plug connector.
Introduci ng the HP P4459A 8-Po rt Fibr e Loop Swi tch 3 Figure 2: Fibre Loop Switch front p anel Table 1 describes the operation of the switch LEDs and Table 2 de scribes the operation of the port LEDs on the front panel of the fibre loop switch.
4 HP P445 9A 8-Port Fi bre Loop Switch In stallati on & Opera tion Gui de Switching Operation The fibre loop switch implements the Fibre Channel Arbitrated Loop protocol. It provides concurrent connections to the storage a rea network (SAN) without changing the FC-AL interface, which most SAN end-node devices normally communicate.
Introduci ng the HP P4459A 8-Po rt Fibr e Loop Swi tch 5 wish to communicate. The addition of a hub, as shown in the center of the same figure, merely allows the cables from each node to go to a centralized location, such as a wiring closet where the hub is located.
6 HP P445 9A 8-Port Fi bre Loop Switch In stallati on & Opera tion Gui de • If node A is free, node C’ s data is forwarded dire ctly to node A without interference. That is, the messages do not circulate through e ach device on the loop and so latency savings on this transaction are also gained.
Introduci ng the HP P4459A 8-Po rt Fibr e Loop Swi tch 7 that it is ready to participate by sending a LIP. Obviously, this interrupts any traffic in progress on that switch port, or on another switch port that is involved in a connection with a device on that switch port.
