2.4.5 Installing the DS-SWX4U-2U External Cache Battery (ECB)
Shelf Mounting Kit
This procedure describes how to install the ECB mounting kit (DS-SWX4U-2U) into an
41U RETMA cabinet. Once the kit is installed, either one or two ECB SBBs can be
mounted into the shelf.
Compaq recommends mounting the ECB shelf in the front of the cabinet directly above
the lower BA370 enclosure. The shelf is capable of holding two ECB SBBs (a single or
dual ECB module). If only one ECB (either a single or dual module) is installed, a blank
bezel must be installed in the other opening of the shelf.
NOTE
If only one BA370 enclosure is installed within the cabinet,
the space
above the ECB shelf must be covered with 5U
and 1U filler panels to provide adequate air flow within the
cabinet. If two BA370 enclosures are installed, no filler
panels are required above the upper enclosure.
If two BA370 enclosures will be installed within the cabinet,
Compaq recommends installing the ECB shelf prior to
installing the second BA370 enclosure in the upper location.
Otherwise, it might be difficult to secure the rear ECB shelf
mounting brackets.
2.4.5.1
Installation Procedure (See Figure 2–21)
Perform the following procedure to install the ECB shelf into the cabinet:
NOTE
Count only the cabinet rail holes that are 0.281 inch in
diameter, beginning at the bottom of the cabinet. DO NOT
count the first smaller hole at the very bottom or top of the
rail.
