Static electricity can permanently damage the integrated circuits on all RLS
PCBAs. There are several CMOS chips on the Drive Bay PCBA Assembly be-
tween the board and the mounting bracket (not visible while assembled).
Standard ANTI-STATIC practices should be employed when working on the
RLS. At a minimum, touch an unpainted portion of the RLS chassis before
handling any PCBAs.
Required Tools and Supplies:
•
No. 1 Phillips Screwdriver
•
No. 2 Phillips Screwdriver
•
5/64-inch Allen (Hex) Wrench
•
3-inch Cable Tie (P/N 669-1001-9)
•
1/4-inch Hex Nut driver or Wrench
7.13.1 Drive Bay PCBA Assembly Removal
1.
Remove power from the RLS by first pressing the power switch off and then re-
moving the power cord (two power cords if dual-redundant power supply mod-
ules are installed).
2.
Follow the instructions in Section 7.21 to remove the Power Supply Module(s).
3.
Remove all the Tape Drives as described in Section 7.11.1.
4.
If the RLS is rack-mounted, follow the steps in Section 7.5.1 to extend the RLS
out of the rack.
5.
Open the Top Cover of the RLS as described in Section 7.6.1.
6.
Follow the instructions in Section 7.19 to remove all of the DFA Duplex Cables
in RLS-8236D and 8244D libraries.
7.
Follow the instructions in Section 7.18 to remove all of the Drive Interface
Adapters (DIAs) in all other RLSmodels.
8.
Follow the instructions in Section 7.17 to remove the Sensor Master Assembly.
9.
Follow the instructions in Section 7.16 to remove the X-Clear Emitter PCBA.
10.
Disconnect the ribbon cable from the STORAG connector on the Drive Bay PCBA
Assembly. See Figure 7-24. Although shown from the left side, it's easiest to re-
move the cable by reaching into the lower-right corner of the space once occupied
by the Power Supply Module(s). The ribbon cable for the Storage Array is short-
er and routed differently than the cable for the Carousel.
