Chapter 1 The Scalar 218 Library This Chapter … p provides a brief overview of the Scalar 218 Library features. For detailed specifications, see Appendix E.
W elcome to your new adic Scalar 218 Library. Your new library is a fully automated, high-performance, high-capacity, mass storage system. The Scalar 218 is designed to provide you with unattended, near-line and off-line data storage, archiving, backup, hierarchical storage management (HSM), and retrieval for mid-range and high-end servers and networks.
Features • Desk-top and Rack-Mounted units. The Scalar 218 is the first desk-top unit to offer over 1 TB of data storage, and it’s attractive case looks great in any office environment. The more utilitarian rack-mounted unit includes all of the features of the desk-top unit, but comes equipped with built-in hardware to allow simple installation into standard 19inch racks. • Multi-function Operator Panel.
• Cartridge Pre-Check. Whenever you power up, your Scalar 218 maps all cartridge locations and, if barcode scan is enabled, the Media Picker will move each cartridge from the storage slots to a position where the barcode reader can scan the barcode data and build a log of valid cartridge locations. • Downloadable Firmware. Both your Scalar 218 and the DLT drives employ Flash EEPROM technology permitting easy on-site installation of firmware updates from the host computer. • Built-in Diagnostics.
Chapter 2 Getting Started This Chapter … p covers what you need (and what you need to know) to install your adic Scalar 218. Read this chapter before you begin installation.
For the most part, installation of the desk-top unit is simply a matter of checking all necessary SCSI connections, installing the application software (backup or otherwise) on the host computer, and applying power. Installtion of the rack-mount unit requires that you first install the rack rails, a cable channel, and channel stop to your rack before continuing the installation. Requirements • Space requirements: your Scalar 218 desk-top unit has a footprint of 19.0" wide by 24.5" deep by 11.0” high.

Appendix C Scalar 218 Rack-Mount Installation This Appendix … p contains complete instructions on how to install your Scalar 218 into your rack.
Preparing the Rack Tools Required + # 1 Phillips Screwdriver + 11/32” Nutdriver p Match the holes in the mounting flange of an outer rail to the holes in your rack upright. You must use holes that have the same spacing when mounting the Scalar in your rack.
p Using a tape measure or other device, measure and record the inside distance between the rack uprights.
p Mount the outer rails to the Scalar 218 by placing each rail over the 3 studs on each side of the unit. Loosely secure the outer rails to the studs using 3 Nylock nuts. Do not tighten the nuts completely. The following illustration shows the location of the rail mounting studs. p Adjust the position of the outer rails until the distance between the outside surface of the mounting flanges is equal to the measurement you recorded when you measured the distance between the rack uprights.
p Using the key, unlock the front panel. p Turn the lock ¼ turn counterclockwise while pushing the plate/rail subassembly rearward until it clears the slides. Note If the front panel lock is unlocked, it is not necessary that you have the key to unlatch it and slide it forward. Simply turn the lock with your hand ¼ turn counterclockwise while pulling the bottom of the front panel towards you. p 80 Slide the Scalar 218 all the way forward until the slide stops engage.
Warning The Scalar 218 weighs 70 pounds when it is equipped with 2 drives. Do Not attempt to lift the Scalar by yourself. To avoid possible injury, and damage to the equipment, always use 2 people to lift the Scalar. p While depressing both slide stop releases, slide the Scalar off the outer slides. If the holes in the uprights of your rack are square, you must install the plate/rail subassembly using the collared spacers included in the hardware. This will position the rails correctly.
Installing the Scalar 218 into the Rack Warning The Scalar 218 weighs 70 pounds when it is equipped with 2 drives. Do Not attempt to lift the Scalar by yourself. To avoid possible injury, and damage to the equipment, always use 2 people to lift the Scalar. p With your assistant, lift the Scalar 218 up and slide the slides into the rails. The slides will continue past the slide stops. It is not necessary to depress them when pushing the Scalar into the rails.
Installing the Cable Channel The next step in the installation process is to install the cable channel bracket, cable channel, and channel stop at the rear of the rack. The cable channel will keep the SCSI cable(s) orderly and prevent them from hampering the movement of the Scalar 218 whenever it is slid forward on the rails. The cable channel is secured to a channel bracket with a quick-release pin.
This completes the rack-mount Scalar 218 installation process. Return to the Preparing the Library section in Chapter 2: Getting Started.
