Replacing a 3216 Tape Controller
4. Tighten the thumbscrews on the ejectors. Be careful not to overtighten the
thumbscrews.
5. Close the cabinet door.
You are now ready to resume operations with the new 3216 logic board. See
Resuming Operations on page 6-15.
Removing a 3216 BIC
Use this procedure to remove a 3216 BIC:
1. At the back of the cabinet, remove the cabinet cover and locate the BIC you are to
remove. To determine the BIC slot number in either a system cabinet or I/O
cabinet, see Identify the System and the Controller on page 2-4.
2. If a cable is connected to the BIC, attach a label to the cable. On the label, write
the name of the BIC connector to which the cable is connected (such as J1 or J4).
Then disconnect the cable from the BIC.
3. Loosen the thumbscrews that secure the BIC to the card cage. (See Figure 1-6 on
page 1-12.) If a thumbscrew does not move with finger pressure, use a slotted
screwdriver to loosen it.
4. Pull on the metal flange around the thumbscrews to remove the BIC from the
cabinet.
You are now ready to install a replacement 3216 BIC.
Installing a 3216 BIC
Use this procedure to install a 3216 BIC:
1. Locate the slot in which to install the BIC. Make sure the BIC label matches the
slot label (I/O). BICs are keyed so you cannot install a BIC in the wrong slot.
2. Slide the BIC into the slot. Press on the front of the BIC so the connectors on the
back of the BIC make contact with the backplane.
3. Make sure the BIC is seated firmly. If the system is powered on, the green
indicator light on the BIC is lit and the red indicator light is unlit. Notify a service
provider such as the GCSC if the red indicator light is lit.
4. Tighten the two thumbscrews to secure the BIC.
5. Remove the filler plug, if necessary, from the J1 connector, and reconnect the
cable that was connected to the original BIC. Check the label on the cable to
make sure that you reconnect the cable to the correct connector.
You are now ready to resume operations with the new 3216 BIC.
