2.4.3 Installing RF- and RZ-Series ISEs

NOTE: Expanded systems conﬁgured at the factory already have ISEs

properly installed.

CAUTION: Static electricity can damage integrated circuits. Use the wrist

strap and antistatic mat found in the Antistatic Kit (part no. 29–26246)

when you work with the internal parts of a computer system.

Handle ISEs with care. Dropping or bumping the ISE can damage the disk

surface. Carry or hold the ISEs by their metal brackets to avoid damaging

the drive module.

Install an ISE as follows:

1. Unpack the ISE.

2. Remove the blank ISE front panel from the expander. The front panels

are each secured with one captive Phillips screw.

3. With the ISE controller module facing the right, slide the ISE along

the guide rails into a mass storage cavity (Figure 2–6A). For single

bus conﬁgurations, install ISEs in the upper mass storage area ﬁrst;

then install ISEs in the lower mass storage area. Always install ISEs

working from right to left.

NOTE: The ﬁrst or rightmost mass storage cavity in the upper mass

storage area is wider than the rest to accommodate a larger device. A

small ﬁller panel is used to ﬁll the gap space when an RF- or RZ-series

ISE is installed in this ﬁrst cavity.

4. Using the upper and lower ﬁnger cutouts on the ISE bracketry, ﬁrmly

push the ISE brackets until the interface card at the rear of the ISE

plugs into its backplane connector (Figure 2–6A). Tighten the two

captive screws.

CAUTION: A small gap between the ISE mounting bracket tabs and the

R400X frame is normal. Tighten the captive screws only until they are

securely fastened. Do not try to force the tabs to ﬁt ﬂush against the

frame.

5. Plug the remote front panel cable into the module inside the ISE front

panel (Figure 2–6B).

NOTE: The ISE front panel for RZ-series ISEs unlike the RF-series front

panel has no buttons or indicators.
