1. Position the mounting rails in the hole positions indicated by Table 8-5
or Table 8-6. The upper and lower studs on the front of the mounting
rails align with the indicated holes on the data center cabinet’s front
vertical rails. The alignment tab slides into a hole on the inner front
vertical rail of the cabinet that corresponds to the middle stud of the
mounting rail. Attach the front of the mounting rail to the front of the
cabinet using two 5/16 inch nuts on the top and bottom studs of each
mounting rail and tighten. See Figure 8-23. DO NOT attach a 5/16 inch
nut to the middle stud of the mounting rail. This is reserved for locking
the BA370 into the cabinet.
2. Slide four U-Nuts onto the rear vertical rails of the data center cabinet
and over the obvious holes that correspond to the rear mounting holes of
the cabinet’s vertical rails, as shown in Figure 8-23. Attach the rear of
the mounting rails to the cabinet by inserting a 10/32 inch x 5/8 inch
screw through the holes in the mounting rails, through the rear vertical
rails of the cabinet and through the U-nuts. Because the front of the
mounting rail was attached to the cabinet in Step 1, the rear hole on the
mounting rail should automatically align with the proper hole on the rear
vertical rail of the cabinet. If you have doubts on proper rear hole
alignment, count the number of holes on the front of the cabinet up to
the middle stud of the mounting rail. The rear screw attachment hole
should correspond to the middle stud hole on the front of the mounting
rail as well as to the alignment tab hole.
3. At this time, install the ECB into the proper position of the ECB shelf.
ECBs (Part Number DS-HS35X-BD) for the ESA10000 can be ordered,
and must be available prior to starting an installation of a BA370 rack-
mountable enclosure. Figure 8-24 shows an ECB being installed into the
right position of the ECB shelf (viewed from the back). An ECB
installed in this position is for the cache modules that are installed in the
upper BA370 rack-mountable enclosure. An ECB installed in the left
position of the ECB shelf is for the cache modules installed in the lower
BA370 rack-mountable enclosure. On the service label, enter the date of
installation, serial number, and revision level on the label. Place the
service label on the shelf below the ECB.
