Product Overview

Basic Description

The ST2122-2 is a 1U, rack-mountable storage router that provides IP hosts access to Fibre Channel storage through an IP network.

Figure 1: Storage router chassis

The SR2122-2 provides access to Fibre Channel storage as if the IP hosts were directly attached to the storage. For more information about the types of storage access available with the storage router, see Chapter 4, “Software Overview” and other related documentation.

Gigabit Ethernet Ports

The Gigabit Ethernet ports are labeled GE 1 and GE 2 (see Figure 3). Each port provides a 1-Gigabit Ethernet interface for connecting to IP hosts that require access to storage. 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 Gigabit Ethernet port has LEDs

indicating its status, as described in Front-Panel LEDs, page 23.

21IP Storage Router SR2122-2 User Guide

Product Overview

Console Port

The console port is labeled CONSOLE (see Figure 3). 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 storage router command line interface (CLI). The console port uses an 8-pin RJ-45 receptacle; it has no LEDs.

Caution: The console cable may be connected to the unit during installation

and maintenance only. The console cable must be disconnected from the unit when not in use during normal operation to minimize the electromagnetic interference.

10/100 Ethernet Management Port

The 10/100 Ethernet management port is labeled MGMT 10/100 (see Figure 3). 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 “Front-Panel LEDs” on page 23.

10/100 Ethernet HA Port

The 10/100 Ethernet high-availability (HA) port is labeled HA 10/100 (see

Figure 3). It is a 10BaseT/100BaseT Ethernet interface for connecting to an HA

network. The port allows the storage router to function in a multiple-node cluster with other 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 “Front-Panel LEDs” on page 23.

Fibre Channel Ports

The Fibre Channel ports are labeled FC 1 and FC 2 (see Figure 3). Each port provides a 1-Gigabit/2-Gigabit Fibre Channel interface for connecting to storage systems, Fibre Channel switches, Fibre Channel hosts, or other HP storage networking products. Each Fibre Channel port can be configured as one of the following port types: G_Port, GL_Port, F_Port, FL_Port, or TL_Port. Each port uses a small form-factor pluggable (SFP) module for connection to the port’s

22 IP Storage Router SR2122-2 User Guide

physical medium. See Chapter 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 that follows.

Front-Panel LEDs

The front-panel LEDs provide status indications about the storage router chassis and its ports (see Figure 4).

■ Each Gigabit Ethernet port, GE 1 and GE 2, has four LEDs, labeled LINK,

RX, TX, and FAULT. The LEDs are located to the left and right of each Gigabit Ethernet port.

■ The FAULT, STATUS, and POWER LEDs indicate the overall status of the

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.

Fan Assembly

The fan assembly provides cooling for the internal chassis components. The storage router chassis contains four exhaust fans that are located on the left side of the chassis. The fans draw air in from the right and exhaust it out through the left.

Product Overview

Power Supply

The SR2122-2 has an internal power supply that monitors its temperature and output voltages. The power supply automatically senses and adjusts to either of these input voltages: 115 VAC/60 Hz or 230 VAC/50 Hz.

If conditions reach critical thresholds, the power supply shuts 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. The power supply is powered on with a rocker switch next to the power connector. The switch is labeled off.

Installation

Site Planning

Planning the proper location and layout of your SR2122-2, your equipment rack, or wiring closet is essential for successful storage router operation. Equipment placed too close together or in a poorly ventilated area can cause the system to overheat. In addition, poor equipment placement can make system panels inaccessible and difficult to maintain.

Table 20 in Appendix A lists the operating and nonoperating environmental site

requirements for the SR2122-2. Within specified environmental ranges, the system can continue to operate; however, a measurement that approaches the minimum or maximum of a range indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental conditions before they exceed the maximum operating range.

Verify the site power for the type of device you are installing. Power requirements are useful for planning the power distribution system needed to support the storage router. Heat dissipation is an important consideration for sizing the air-conditioning requirements for an installation. See Tabl e 20 in Appendix A for power and heat ratings for the SR2122-2.

Caution: To prevent a loss of input power, verify that the total maximum load

on the circuit supplying power to the power supply is within the current ratings of the wiring and breakers.

Installing the Storage Router

You can install the SR2122-2 on a table or a shelf, or in an equipment rack. The following sections describe the steps required to install the storage router:

■ Installing on a Table or a Shelf

■ Rack-Mounting the Storage Router

■ Installing SFP Modules

28 IP Storage Router SR2122-2 User Guide

Installing on a Table or a Shelf

You can install the storage router on a table or a shelf (or another flat, secure surface).

If you are going to install the storage router in an equipment rack, skip this section and proceed to the “Rack-Mounting the Storage Router” section. To install the chassis on a table or a shelf:

1. Locate the four adhesive-backed rubber feet in the accessory kit that is shipped with the storage router.

2. Peel the rubber feet from their backing and place the feet onto the four round recessed areas on the bottom of the chassis.

3. Place the storage router on a table or a shelf near an AC power source.

Rack-Mounting the Storage Router

You can rack-mount the SR2122-2 in a 19-inch equipment rack with the front panel forward.

The accessory kit shipped with your storage router contains:

■ two rails

Installation

■ two wing nuts

■ various screws

You need the following tools to install the SR2122-2 in a rack:

■ Phillips screwdriver

■ Tape mea s ure

To install the SR2122-2 in a rack:

1. Prepare for installation:

a. Place the storage router on the floor or on a sturdy table as close as

possible to the rack. Leave enough clearance so that you can move around the storage router.

b. Use a tape measure to measure the depth of the rack. Measure from the

outside of the front mounting uprights to the outside of the rear mounting uprights. The depth must be at least 19 inches (48.26 cm) but not more than 32 inches (81.3 cm).

29IP Storage Router SR2122-2 User Guide

Installation
