The SFP and XPAK transceivers are hot-pluggable. This means that you can
remove or install a transceiver while the switch is operating without harming the
switch or the transceiver. However, communication with the connected device will
be interrupted. For more information about installing and removing transceivers,
refer to
“Install the Transceivers” on page 3-5 .
Port Types
QLogic 5800V Series switches support generic ports (G_Port, GL_Port), fabric
ports (F_Port, FL_Port), and expansion ports (E_Port). Switches come from the
factory with all SFP ports configured as GL_Ports. The XPAK ports come from the
factory configured as G_Ports. Generic, fabric, and expansion ports function as
follows:
Table 1-1. Fibre Channel Port Types
Port type Description
GL_Port Generic loop port—self-configures as an FL_Port when connected to
a loop device, as an F_Port when connected to a single device, or as
an E_Port when connected to another switch. If the device is a single
device on a loop, the GL_Port will attempt to configure first as an
F_Port, then if that fails, as an FL_Port.
G_Port Generic port—self-configures as an F_Port when connected to a sin-
gle device, or as an E_Port when connected to another switch.
FL_Port Fabric loop port—supports a loop of up to 126 devices. An FL_Port
can also configure itself during the fabric login process as an F_Port
when connected to a single device (N_Port).
F_Port Fabric port—supports a single device.
E_Port Expansion port—expands the fabric by connecting switches. The
switch self-discovers all inter-switch connections. For more informa-
tion, see
“Multiple Chassis Fabrics” on page 2-6 .
TR_Port Transparent routing port—expands the fabric by connecting an QLogic
5800V Series switch to a Brocade
® or Cisco ® remote fabric. The
TR_Port provides transparent communication between local fabric
devices and remote fabric devices while maintaining separate fabrics.
