Removing ISEs from the BA200-Series
Enclosure
1.1 Removing ISEs
This chapter describes how to remove the TK-series and 5.25-inch form factor
RF-series Integrated Storage Elements (ISEs) from the BA200-series enclosure.
Note
This chapter depicts the BA215 enclosure for most of the removal
procedures. Duplicating the same basic illustrations for the BA213
enclosure is unnecessary as the removal procedure is the same for both
enclosures. Procedures unique to the BA213 are depicted.

1.2 Accessing ISEs
Before you can remove ISEs from the BA200-series enclosure, you must:
•

Remove the front panel.

•

Remove the media faceplate covering the mass storage area.

•

Remove the OCP (Operator Control Panel).

•

Remove the bottom media cover (R215F only).
Note
If the DSSI bus is connected to another DSSI expander or is part of a
dual-host system, all enclosures connected to that DSSI bus must be
turned off.

1.2.2 Removing the Media Faceplate
You must remove the media faceplate before you can remove either a disk
drive, or a tape drive.
Remove the media faceplate as follows:
Caution
Static electricity can damage integrated circuits. Always use the
antistatic wrist strap and antistatic pad found in the static-protective
field service kit (P/N 29-26246-00) when working with the internal
parts of the computer system.

1. Remove the front panel, using the procedure in Section 1.2.1.
2. Put on the grounded wrist strap included in the antistatic kit
(P/N 29-26246-00), and attach the alligator clip to the BA200 frame.
3. If installed, you must remove the DSSI expansion cable (BC21M) from the
external device connector. If the DSSI bus is connected to another DSSI
expander or is part of a dual-host system, all enclosures connected to that
DSSI bus must be turned off.
4. Loosen the captive screws that hold the media faceplate to the BA215
frame (see Figure 1–2A) or the BA213 frame (see Figure 1–2B) and remove

1.2.3 Removing the Operator Control Panel (OCP)
The BA200 enclosure mass storage area contains an operator control panel
(OCP) for DSSI mass storage devices.
Remove the OCP from the enclosure as follows:
Caution
Static electricity can damage integrated circuits. Always use the
antistatic wrist strap and antistatic pad found in the static-protective
field service kit (P/N 29-26246-00) when working with the internal
parts of the computer system.

1. Remove the media faceplate, using the procedure in Section 1.2.2.
2. Loosen the straight-slotted captive screw that holds the top of the operator
control panel (OCP) to the BA215 frame (Figure 1–3). (Note: The BA213
OCP will have two screws.)
3. The OCP is held onto the bottom of the BA200 frame by tabs that fit into
slots on the frame. Lower the OCP, allowing the OCP to rest on its tabs
(Figure 1–3).
4. Disconnect all cables from the OCP.
Note
Make sure you label all cables in case the OCP has to be reinstalled.
(For example, if only some of the disks are being transported.)
For BA213 enclosures, the 50-pin DSSI ribbon cable must also be
disconnected from OCP assembly before the OCP can be removed. Pull out
the black plastic stud located behind the external DSSI port on the upper
left portion of the panel. This action releases the external DSSI connector
and the internal DSSI cable.
5. Lift the OCP from the slots on the BA200 frame and remove.

5. Make sure that the front mounting screw on the bottom outside bracket is
installed through both the mating hole and the grounding foil beneath it.
6. Connect the power (5-pin) and signal (50-pin) cables to each drive.
7. Connect the remote front panel cable(s) provided in the upgrade kit to the
controller module(s) on the storage device(s).

3.3 Installing an RF-Series ISE in the BA400-Series
Enclosure
To install an RF-series ISE into a BA400-series enclosure, perform the
following procedures.

3.3.1 ISE Installation
Caution
Static electricity can damage integrated circuits. Use the antistatic
wrist strap and antistatic pad found in the static-protective field
service kit (P/N 29-26246-00) when you work with the internal parts of
a computer system.
Handle the RF-series ISE with care. Dropping or bumping the ISE can
damage the disk surface. Carry or hold the ISE by the underside of the
lower bracket to avoid damaging the drive module.

1. After the system manager shuts down the operating system, open the
enclosure door, set the Power switch to off (0) (Figure 3–5).

2. Always install ISEs working from right to left (Figure 3–6).
Note
The first or right-most mass storage cavity in the mass storage area
is wider than the rest to accommodate a larger device such as a tape
drive. A small filler panel (70–27414–001) is used to fill the gap when
an RF-series ISE is installed in this first cavity.

3. Loosen the captive Phillips screw at the top of the blank ISE front panel
assembly, and remove the panel. The location of the Phillips screw is
shown on a sample device in Figure 3–7D.
4. For the 5.25-inch form factor ISE, with the ISE controller module facing to
the right, slide the ISE along the guide rails into the mass storage cavity
(Figure 3–7A).
For the 3.5-inch ISE, with the controller module facing to the left, slide the
ISE along the guide rails into the mass storage cavity (Figure 3–7A).

3.3 Installing an RF-Series ISE in the BA400-Series Enclosure
5. Using the upper and lower finger cutouts on the ISE brackets, firmly push
the ISE brackets until the interface card at the rear of the storage device
plugs into its backplane connector. The guide tabs on the upper and lower
bracket should line up with the cutouts in the chassis. Tighten the two
captive screws (Figure 3–7A).
Caution
It is normal for there to be a small gap between the ISE mounting
bracket tabs and the enclosure frame. Tighten the captive screws only
until they are securely fastened (9 in/lbs torque). Do not try to force
the tabs to fit flush against the frame.

6. Plug the remote front panel cable(s) into the connector(s) inside the ISE
front panel.
For 5.25-inch ISEs see Figure 3–7B.
For 3.5-inch ISEs see Figure 3–7C.
For the 5.25-inch ISEs only, use the Velcro fastener on the cable and on the
inside of the ISE front panel to secure the remote front panel cable. The
3.5-inch ISEs have a different connector scheme that does not require the
Velcro fastener.
Note
If the 3.5-inch ISE contains two storage devices, two remote front panel
cables must be connected to the front panel. If the ISE contains only
one storage device, only one remote front panel cable must be connected
to the front panel.

7. Attach the ISE front panel to the enclosure by inserting the panel’s lower
tabs into position. Secure the panel with its single captive Phillips screw
(Figure 3–7D).

3.3.2 Bus Node ID Plug Installation
Bus node ID plugs have prongs at the rear that identify the bus node number
(and by default, the unit number) of the ISEs to the system. Bus node ID plugs
are shipped with the system.
To insert a bus node ID plug (P/N 12-28766-19), align the two center prongs
with the two center slots of the receptacle on the ISE front panel (Figure 3–8).
Push the plug firmly into the receptacle. To remove a bus node ID plug, grasp
it firmly and pull it straight out.
Follow the rules below for numbering IDs for RF-series ISEs:
•

For each DSSI bus controller, do not duplicate bus node numbers for
storage elements. You can have only one storage element on bus 0
identified as node 0, one storage element as node 1, and so on.

•

By convention, the ISEs are numbered in increasing order from right to left
and top to bottom, starting with 0.
Note
The DSSI node ID address assigned by the plug is read only during
the power-up sequence. If you change the bus node ID plug while the
system is operating, you must turn off the system and then turn it back
on for the new plug addresses to take effect.
