Introduction 3

Introduction 0

This document explains how to install a stand-alone Sun StorEdge™

L25 Tape Library or Sun StorEdge™ L100 Tape Library. Hereafter in

this document, these libraries will be referred to as the L25 and the

L100, respectively.

Site Requirements 0

When selecting an installation site for the library, consider the

following requirements:

•Space Requirements

•Cooling Considerations

•Environmental Requirements

•Power and Grounding

Space Requirements 0Table 1 lists the dimensions of the L25 and L100 libraries.

Table 1 Library

Dimensions

Note: To install an L25 or L100 library module in a multiple library

stack, refer to the StackLink Installation Instructions

(PN 6423029).

Caution: Allow at least 5 inches (12.7 cm) of space behind the

library to allow proper ventilation.

4 Site Requirements

Cooling

Considerations 0

Cooling is one of the most important factors to consider when selecting

a location for the library. The L25 and L100 libraries are force-cooled:

air is drawn into the library through vents at the lower edge of the

front bezel and exhausted through vents at the back of the library. To

ensure that the library is adequately ventilated:

• Place the library on a hard, level surface, or in a standard 19-inch

rack.

• If the library will be placed in a rack, the rack must be open or

ventilated so that the air temperature behind the library at the air

outlets is less than 104°F (40°C).

• Verify that no cables obstruct the vents at the back of the library

(see figure 1 and figure 2).

• Verify that nothing obstructs the vents at the lower edge of the

front bezel.

• Allow at least 5 inches (12.7 cm) of space behind the library or rack.

• Do not install the library near a heater or radiator which could

warm the air drawn into the library.

Site Requirements 5

Figure 2 Vent Locations,

L100

Environmental

Requirements 0

The installation site (desktop or deskside library) or the interior of the

rack (rack mount library) must meet the following environmental

requirements:

• Humidity: 20% to 80%, non-condensing

• Temperature: 50°F to 104°F (10°C to 40°C)

• Altitude: -100 to +10,000 feet (-30 to +3,000 meters)

Power and

Grounding 0

The L25 and L100 power supplies accept 88 VAC to 264 VAC input

power at 47 Hz to 63 Hz.

The library must be connected to a grounded power outlet. If the

library is mounted in a rack, the rack must also be grounded.

6 Installing a Desktop or Deskside Library

Installing a Desktop or Deskside Library 0

This section explains how to install a desktop L25 library or a deskside

L100 library. To install a rack mount library, see Installing a Rack

Mount Library.

Installing a Desktop

L25 Library 0

To install a desktop L25:

1Convert the L25 to a desktop unit by performing the procedures

detailed in the Sun StorEdge™ L25 Tape Library Rack Mount to

Desktop Conversion Instructions (PN 6421032).

This document is provided with the Sun StorEdge™ L25 Tape

Library Rack Mount to Desktop Conversion Kit.

2Place the library in the installation location, preferably on a sturdy

desk or tabletop.

3Proceed to Installing Drives in the Library on page 18 to continue

the installation procedure.

Installing a Deskside

L100 Library 0

To install a deskside L100:

1Convert the L100 to a deskside unit by performing the procedures

detailed in the Sun StorEdge™ L100 Tape Library Rack Mount to

Deskside Conversion Instructions (PN 6423027).

This document is provided with the Sun StorEdge™ L100 Tape

Library Rack Mount to Deskside Conversion Kit.

2Place the library in the installation location.

3Proceed to Installing Drives in the Library on page 18 to continue

the installation procedure.

Note: The procedures in this section assume that you have already

unpacked the library. If you have not, do so now, referring to

the Sun StorEdge™ L25 Tape Library Unpacking Instructions

(PN 6421029) or the Sun StorEdge™ L100 Tape Library

Unpacking Instructions (PN 6423014).

Installing a Rack Mount Library 7

Installing a Rack Mount Library 0

This section explains how to install an L25 or L100 library in a

standard 19-inch rack.

Determining the

Position of the

Shelves in the Rack 0

Before starting the rack mount installation:

1Determine the proper position of the shelves in the rack:

• An L25 library uses 4U of vertical space.

• An L100 library uses 13.5U of vertical space.

• The StackLink mounting hardware uses 1U of vertical space at

the top of the rack, and either 1U or .5U at the bottom of the

rack (see the StackLink Installation Instructions, PN 6423029, for

more information).

2Use a pencil to mark the desired shelf position on the rack rails.

Note: The procedures in this section assume that you have already

unpacked the library. If you have not, do so now, referring to

the Sun StorEdge™ L25 Tape Library Unpacking Instructions

(PN 6421029) or the Sun StorEdge™ L100 Tape Library

Unpacking Instructions (PN 6423014).

Caution: Take rack stability into account when determining

where to place the library in the rack.

Note: 1U equals 1.75 inches (44.45 millimeters).

Installing the Shelves in a Half U Position 0

To install the rack mount shelves in a half U position:

1Position the left shelf in the rack, aligning the bottom of the shelf

with the pencil marking you made in step 2 on page 7.

2Use six screws (PN YS42086) and washers (PN 217406) to secure

the shelf to the rack rails as shown in figure 3.

3Repeat steps 1and 2to install the right shelf.

Note: In half U position, the bottom of the rack mount shelf lines

up with the middle of a U.

Note: Do not tighten these screws fully; you will finish

tightening them later in this procedure.
