Introduction
1.1 Introduction
The BA370 StorageWorks shelves are normally factory installed in either H9A10 or
H9A15 cabinets that have an EIA rail-hole pattern. These cabinets can be upgraded in the
field by adding additional BA370 StorageWorks shelves.
The standard depth H9A10 cabinet can normally have one BA370 shelf mounted in the top
front of the cabinet, while the extended depth H9A10 cabinet can have one BA370 shelf
mounted in the top front and one BA370 shelf mounted in the top rear.
The standard depth H9A15 cabinet can normally have two BA370 shelves mounted one
above the other in the front of the cabinet, while the extended depth H9A15 cabinet can
have two BA370 shelves mounted one above the other in the front and two BA370 shelves
mounted one above the other in the rear.

1.2 Types of Installation
There are three ways of mounting the BA370 shelves in the H9A10 and H9A15 cabinets.
These three mounting types are:
•

Front fixed mounting

•

Front slide mounting

•

Rear fixed mounting

The front fixed mounting is used when there are only going to be front mounted BA370
shelves in the cabinet.
The front slide mounting is used when BA370 shelves are going to be front and rear
mounted in the same cabinet. This allows the front shelf to be extended from the cabinet to
allow access to the rear of both shelves for maintenance.

DIGITAL DS-BA370-AA RAID StorageWorks Shelf Field Installation Guide 1–1

Introduction

The rear fixed mounting is used for all rear mounted BA370 shelves in the cabinet.
The standard depth H9A10 cabinet can have one front fixed mounted or one front slide
mounted BA370 shelf in the top of the cabinet. The extended depth H9A10 cabinet can
have one front slide mounted BA370 shelf in the top front of the cabinet and one rear fixed
mounted BA370 shelf in the top rear of the cabinet.
The standard depth H9A15 cabinet can have two front fixed mounted or two front slide
mounted BA370 shelves in the front of the cabinet. The extended depth H9A15 cabinet
can have two front slide mounted BA370 shelves in the front of the cabinet and two rear
fixed mounted BA370 shelves in the rear of the cabinet.
An optional front door and bezel kit is available for front fixed and slide mounted BA370
shelves that are installed in H9A10 and H9A15 cabinets that do not have a front door.

2.2 Installation Kits
Four different kits are available for installing the BA370 shelf in an H9A10 or H9A15
cabinet. The kit used, or the combination of kits used, depends on the type of installation
that is being performed. An optional front door and bezel kit is available for the front fixed
and slide mounted BA370 shelves that are installed in H9A10 and H9A15 cabinets that do
not have a front door.
A field mounting kit (2T-BA370-FI) is required for installing a front fixed or rear fixed
mounted BA370 shelf. This kit basically consists of two rails that are temporarily installed
to support the BA370 shelf while the shelf is being secured in the cabinet. After the BA370
shelf is secured in the cabinet, these two rails are removed. Table 2-1 lists the components
included in the 2T-BA370-FI field mounting kit.

2.3 Site Preparation
The installation instructions that follow assume that:
•

Power down and disconnect electrical power from any existing BA370 shelves or
other equipment that is presently installed in the cabinet.

•

All cables that you plan to connect to the BA370 shelf are in place and clearly labeled.

•

The system is located in an area that provides sufficient clearance for ventilation and
servicing. A clearance of 61 cm (24 in.) at the rear and 129.6 cm (51 in.) at the front
of the cabinet is required for service.
________________________ Caution ___________________________
Do not impede airflow by obstructing the front and rear of the cabinet.
Exceeding internal thermal limits can affect system reliability.
___________________________________________________________

2–6 DIGITAL DS-BA370-AA RAID StorageWorks Shelf Field Installation Guide

Installation

•

Adjust the leveler feet downward so that the cabinet is level and the load is removed
from the casters.
_________________________ Caution ___________________________
Ensure that the leveler feet extend enough to carry the load of the cabinet so that
the casters spin freely. If not, the stability of the cabinet may be compromised.
____________________________________________________________

•

Fully extend the stabilizer bar(s) and adjust the feet at the end of the stabilizer bar(s)
until they touch the floor.
________________________WARNING __________________________
The stabilizer bar(s) must be fully extended before any system is extended
out of the cabinet on its slides or a heavy system is installed in the top of the
cabinet to prevent the cabinet from tipping over.
____________________________________________________________
________________________WARNING __________________________
The BA370 StorageWorks shelf can weigh over 45.36 kg (100 lb). Use
sufficient personnel or the proper lifting equipment to remove the BA370
shelf from the shipping carton and for installing the BA370 shelf in the
cabinet.
____________________________________________________________
________________________WARNING __________________________
If one or two BA370 StorageWorks shelves are installed in the top of an
H9A15 cabinet and no equipment of any substantial weight is being installed
below the BA370 StorageWorks shelves, a weight kit (PN H9C10-MC) must
be installed in the bottom of the cabinet to prevent the cabinet from being
top heavy.
____________________________________________________________

2.4 DS-BA370-AA StorageWorks Shelf Preparation
Before installing the BA370 shelf in the cabinet, some components need to be removed in
order to reduce the weight of the shelf. Remove the following components:
•

Remove the six fan assemblies from the rear of the BA370 shelf.

DIGITAL DS-BA370-AA RAID StorageWorks Shelf Field Installation Guide 2–7

Installation

•

Remove all power supplies from the BA370 shelf.

•

Remove all controller modules from the BA370 shelf.

•

Remove any disk drives from the BA370 shelf.

2.5 Installing the BA370 StorageWorks Shelf
The following sections contain the procedures for the three ways of mounting the BA370
shelf in an H9A10 or H9A15 cabinet.

2.5.1 Front Fixed Mounting
The front fixed mounting is used when there are only going to be front mounted BA370
shelves in the cabinet and requires the use of the 2T-BA370-FI field mounting kit and the
2T-BA370-KF front fixed mounting kit. The standard depth H9A10 cabinet can have one
front fixed mounted BA370 shelf in the top of the cabinet. The standard depth H9A15
cabinet can have two front fixed mounted BA370 shelves in the front of the cabinet.
The following sections contain the procedures for fixed mounting the BA370 shelf in the
front of an H9A10 or H9A15 cabinet.
2.5.1.1 Installation Area and Rail-Hole Pattern
The front fixed mounted BA370 StorageWorks shelf requires 80.0 cm (31.5 in.) of vertical
space or 54 contiguous holes in a 48.26-cm (19-in.) cabinet with an EIA rail-hole pattern.
The holes in the EIA rail-hole pattern rails follow a pattern of 1.27 cm (0.50 in.), 1.59 cm
(0.625 in.), and 1.59 cm (0.625 in.). This pattern is called a set and is repeated for the
length of the cabinet rails.
To determine the installation area, perform the following steps at the front cabinet rails
(refer to Figure 2-1).
1.

If the BA370 shelf is being installed in the top of the cabinet, measure down 80.0 cm
(31.5 in.) from the top of the cabinet. If the BA370 shelf is being installed below a
previously installed shelf, measure down 80.0 cm (31.5 in.) from the bottom of the
previously installed shelf.
If a battery mounting bracket is going to be installed on top of the BA370 shelf,
measure down 84.46 cm (33.25 in.) from the top of the cabinet or from the bottom of
the previously installed shelf.

At the measured point, make a mark between two holes that have a 1.27 cm (0.05 in.)
space between them. This is the starting point of the installation area. The area above
this mark is the installation area. The bottom hole of the installation area is identified
as hole 1 of the installation area.

Repeat steps 1 and 2 for the same holes on the front of both front rails.

2.5.3 Rear Fixed Mounting
The rear fixed mounting is used for all rear mounted BA370 shelves in the cabinet and
requires the use of the 2T-BA370-FI field mounting kit and the 2T-BA370-KR rear fixed
mounting kit. The extended depth H9A10 cabinet can have one rear fixed mounted BA370
shelf in the top of the cabinet. The extended depth H9A15 cabinet can have two rear fixed
mounted BA370 shelves in the rear of the cabinet.
The following sections contain the procedures for fixed mounting the BA370 shelf in the
rear of an H9A10 or H9A15 cabinet.
2.5.3.1 Installation Area and Rail-Hole Pattern
The rear fixed mounted BA370 StorageWorks shelf requires 84.46 cm (33.25 in.) of
vertical space or 57 contiguous holes in a 48.26-cm (19-in.) cabinet with an EIA rail-hole
pattern.
The holes in the EIA rail-hole pattern rails follow a pattern of 1.27 cm (0.50 in.), 1.59 cm
(0.625 in.), and 1.59 cm (0.625 in.). This pattern is called a set and is repeated for the
length of the cabinet rails.
To determine the installation area, perform the following steps at the rear cabinet rails
(refer to Figure 2-20).
1.

If the BA370 shelf is being installed in the top of the cabinet, measure down 84.46 cm
(33.25 in.) from the top of the cabinet. If the BA370 shelf is being installed below a
previously installed shelf and a front slide mounted shelf is installed in the top front of
the cabinet, measure down 88.9 cm (35 in.) from the bottom of the previously
installed shelf.

Repeat steps 1 and 2 for the same holes on the front of both rear rails.
