WARNING:
■ Installing the BA370 into an ESA 100000 requires two people. Never
attempt to lift the BA370 by yourself. Doing so may cause injury, damage
the equipment, or both.
■ Never install a BA370 into the upper position of an ESA10000 unless there
is a BA370 already residing in the lower position. Doing so may cause
injury, damage the equipment, or both.
■ Never attempt to install the BA370 with SBBs installed. You must first
remove all power supply and disk drive SBBs from the BA370 before
completing this installation.
■ Serious personnel injury can result if correct safety precautions are not
taken when installing the BA370 rack-mountable enclosure
1. If power is applied to the cabinet, power down the HSZ70 controllers by
following the procedure contained in the DIGITAL StorageWorks
HSZ70 Array Controller HSOF Version 7.0 Service Manual. Remove
AC power to the BA370 by moving the switch on the AC power
controllers to 0. Remove AC power to the Power Distribution Unit
(PDU) by moving the breaker switch to 0. Disconnect the power
distribution unit from the AC power source.
2. When you install an additional BA370 into the cabinet, you must also
install and tie-wrap the external cache battery (ECB) cable that connects
the HSZ70 controller to the ECB. Your ESA10000 comes precabled for
AC power. For the bottom BA370, tie-wrap each ECB cable to the
bottom hole on both front vertical siderails of the cabinet in the general
vicinity of the AC power cables that come pre-installed and tie-wrapped.
For the top BA370, tie-wrap each ECB cable in the general vicinity of
the AC power cords tie-wrapped to the vertical rails. Leave the ECB
cable extended in the front approximately 10 inches. This ensures that
the ECB cables can be plugged into the cache modules. Tie-wrapping
ensures that the ECB cables are not damaged when you install a BA370.
3. Tuck the ECB cables and AC power cords behind the front vertical rail
of the BA370. Remember, you left the ECB cables extended by 10
inches. Failure to tuck the cables behind the cabinet rails may cause
damage to the cables when you install the BA370 into the cabinet.
4. Position the BA370 on the floor in front of the cabinet. Remove ALL
power supply and disk drive SBBs from the BA370 BEFORE
attempting to lift the BA370
