Installing and configuring a Cisco SN 5428-2 Storage Router consists of the following tasks:

Install the SN 5428-2 Storage Router according to the Cisco SN 5428-2 Storage Router Hardware Installation Guide (this manual).

Select how the SN 5428-2 will be deployed: SCSI routing, transparent SCSI routing, or FCIP.

Configure the SN 5428-2 Storage Router software according to the SN 5428-2 Storage Router Software Configuration Guide.

Install and configure the Cisco iSCSI drivers in IP hosts connected to the storage router (for SN 5428-2s deployed for SCSI routing and transparent SCSI routing only).

This chapter is the starting point for installing the SN 5428-2 Storage Router hardware. The chapter provides some very basic information you should know before proceeding to other chapters in this manual and contains the following topics:

SN 5428-2 Basic Description

The SN 5428-2 Storage Router is a 1U rack-mountable chassis (see Figure 1-1) with two 1-Gigabit Ethernet ports, a serial console port, a 10/100 Ethernet management port, a 10/100 Ethernet high availability (HA) port, and eight Fibre Channel ports.

Gigabit Ethernet Ports

The Gigabit Ethernet ports are labeled GE 1 and GE 2. (See Figure 1-2.) Each port provides a 1-Gigabit Ethernet interface for connecting to IP hosts that require IP access to storage. Each port uses a small form-factor pluggable (SFP) module for connection to the port's physical medium. See "Cable and Port Pinouts" for SFP module specifications. Each Gigabit Ethernet port has LEDs indicating its status, as described in the "Front-Panel LEDs" section.

Console Port

The console port is labeled CONSOLE. (See Figure 1-2.) It is an EIA/TIA-232 interface for connecting to the serial port of a PC running terminal emulation software. Using the console port you can manage the storage router with the SN 5428-2 Storage Router command-line interface (CLI). The console port uses an 8-pin RJ-45 receptacle. It has no LEDs.

10/100 Ethernet Management Port

The 10/100 Ethernet management port is labeled MGMT 10/100. (See Figure 1-2.) It is a 10BaseT/100BaseT Ethernet interface for connecting to a management network. Through a management network you can manage the storage router using the CLI, the web-based GUI, or SNMP. The 10/100 Ethernet management port uses an 8-pin RJ-45 receptacle and has LEDs indicating its status, as described in the "Front-Panel LEDs" section.

10/100 Ethernet HA Port

The 10/100 Ethernet high availability (HA) port is labeled HA 10/100. (See Figure 1-2.) It is a 10BaseT/100BaseT Ethernet interface for connecting to an HA network. The port allows the SN 5428-2 to function in a multiple-node cluster with other SN 5428-2 Storage Routers to provide fault-tolerant operation.The 10/100 Ethernet HA port uses an 8-pin RJ-45 receptacle and has LEDs indicating its status, as described in the "Front-Panel LEDs" section.

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 "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.

The 10/100 Ethernet management port, MGMT 10/100, has two LEDs, labeled ACT and SPEED. The ACT LED is located at the left-bottom corner of the port; the SPEED LED is located at the right-bottom corner of the port.

The 10/100 Ethernet HA port, HA 10/100, has two LEDs, labeled ACT and SPEED. The ACT LED is located at the left-bottom corner of the port; the SPEED LED is located at the right-bottom corner of the port.

Each Fibre Channel port, FC 1 through FC 8, has two LEDs, labeled ACT and LOG. The LEDs are located to the left of each Fibre Channel port.

Table 1-1 describes the LED indications.

When credits from the donor port are being added to another port, the donor port's LOG LED is on to show that the port's buffers are in use. For more information about donor ports, refer to the Cisco SN 5428-2 Storage Router Software Configuration Guide.

Flashing once per second indicates that the port connection is in the process of logging in.

Flashing twice per second indicates that the port connection is broken or an error condition exists with the port. For troubleshooting information refer to "Troubleshooting a Connection to a Fibre Channel Port" section.


Fan Assembly

The fan assembly provides cooling for the internal chassis components. The SN 5428-2 chassis contains two exhaust fans that are located on the rear of the chassis. The fans draw in air from the front and exhaust air to the rear. (See Figure 1-4.)

Figure 1-4 Chassis Airflow

Power Supply

The SN 5428-2 Storage Router has an internal power supply that monitors its temperature and output voltages. The power supply automatically senses the source and will adjust to an input voltage range between 90 VAC - 264 VAC 50/60 Hz.

If conditions reach critical thresholds, the power supply will shut down to avoid damage from excessive heat or electrical current. The power supply connects to site power through a power cord and the power connector on the rear panel. (See Figure 1-5.) The power supply is powered on with a rocker switch that is next to the power connector. The switch is labeled | and O. Pressing | switches power on. Pressing O switches power off.
