Chapter 1 Product Overview
Front-Panel LEDs
Fibre Channel Ports
The Fibre Channel ports are labeled FC 1 through FC 8. (See Figure 1-2.) Each
port provides a 1-Gigabit/2-Gigabit autosensing Fibre Channel interface for
connecting to storage systems, Fibre Channel switches, Fibre Channel hosts, or
other Cisco storage networking products.
Each Fibre Channel port can be configured as one of the following port types:
E_Port, F_Port, FL_Port, G_Port, GL_Port, TL_Port, or donor port.
Note Note that the sole purpose of a donor port is to extend buffer credits to other ports;
a donor port cannot provide connectivity to any FC device.
Each port uses a small form-factor pluggable (SFP) module for connection to the
port’s physical medium. See Appendix B, “Cable and Port Pinouts” for SFP
module specifications. Each Fibre Channel port has LEDs indicating its status, as
described in the “Front-Panel LEDs” section.
The storage router contains two internal Fibre Channel interfaces to allow access
between the GE ports and the Fibre Channel ports, FC 1 through FC 8. These two
internal Fibre Channel interfaces are named fci1 and fci2. As Fibre Channel
initiators, these interfaces are assigned World Wide Port Numbers (WWPN);
therefore, fci1 is also referred to as initiator WWPN1 and fci2 is also referred to
as initiator WWPN2. There are no hardware installation tasks for these interfaces;
however, it is important to be aware of this internal architecture and the WWPNs
for some software configuration tasks that require these port WWPNs (such as
zoning).
Front-Panel LEDs
The front-panel LEDs provide status indications about the SN 5428- chassis and
its ports. (See Figure 1-3.)
Each Gigabit Ethernet port, GE 1 and GE 2, has three LEDs, labeled LINK, TX,
and RX. The LEDs are located to the left of each Gigabit Ethernet port.
The FAULT, STATUS, and POWER LEDs indicate the overall status of the
SN 5428 Storage Router. The LEDs are located to the left of the CONSOLE port.
