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 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).

in the Rack 0
This section explains how to install the library in the rack. You will
need a no. 2 POZIDRIV screwdriver for this procedure.
Installing an L25 Library 0
To install an L25 library in a rack:
1Take precautions to ensure that the rack is stable:
• If you are installing the library at the top of a rack with no
equipment at the bottom of the rack, purchase a rack
stabilization kit from the rack manufacturer and install it before
installing the library.
• If you are installing the library in a rack with other equipment,
place the heaviest equipment at the bottom of the rack.
2Verify that the rack mount shelves are level and securely fastened
to the rack.
3With the help of another person, lift the library onto the rack
mount shelves.
4Slide the library all the way into the rack.
5Press the white button next to the left magazine access door and
open the door.
6Notice the hole behind the magazine access door, at the lower edge
of the library (see figure 9).
This hole provides access to the rack mount clamp screw.

need a TORX®T-20 screwdriver and a flat blade screwdriver for this
procedure.
Installing Tape Drives
in an L25 0
To install tape drives in an L25:
1At the back of the library, use a TORX T-20 screwdriver to remove
the cover plate protecting the drive bay in which you will install
the tape drive.
2Insert the tape drive into the drive bay slowly until the connectors
are seated (see figure 11).
3Tighten the tape drive thumbscrew using a flat blade screwdriver.
4Repeat steps 1through 3to install another tape drive, if desired.
