RA7000 and ESA10000 Storage Subsystems
2–22
EK–SMCPP–UG. A01
WARNING
Installing the BA370 into an ESA10000 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 residing in the lower position already.
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 SW600 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 SW600 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.
