1Before You Begin
Before installing the entry/exit port, do the following:
4Make sure the environment is free of conditions that could cause electrostatic
discharge (ESD). If possible, use an antistatic mat and a grounded static
protection wristband during this procedure.
4Obtain the following tools:
4T-15 and T-20 TORX drivers
4Wire cutters or scissors
4Make sure that there are no cartridges loaded in the tape drives. If necessary,
use the LCD commands to move cartridges out of the tape drives.
4Use the Unlock Entry/Exit Port Door option on the Access menu to unlock
the entry/exit port, then remove the entry/exit port caddy, if it is present.
4Power off the library and disconnect the power cord.
Warning Before performing this maintenance procedure, be sure that the library power
switch is in the off position and that the power cord is disconnected from the
library and the outlet.

To install an entry/exit port, follow these steps:
1.
1.1.
1. Orient the entry/exit port assembly with the motor toward the bottom, as
shown in Figure 3. Angle the top of the assembly into the gap between the
two sets of cartridge slots, then rotate it down into place. Make sure that no
cables are caught under the assembly.
Caution The entry/exit port state sensors are attached to the top of the assembly. Be careful
not to bump the sensors against the cartridge slots above the opening as you move
the assembly into place.

cables to the door.
5Calibrate the Entry/Exit Port
After replacing an entry/exit port, you must calibrate the new entry/exit port to
establish the precise location of the slots in the entry/exit port caddy.
Note: If you installed an entry/exit port in a library that did not already have one
installed, the library performs the calibration automatically after it
completes its power-on self-test (POST).
During calibration, the robot picks the calibration cartridge (shown in
Figure 5) and places it into each of the cartridge slots in the entry/exit port
caddy, scanning the calibration cartridge’s target to determine its exact
position. The robot then returns the calibration cartridge to its slot.
Caution Make sure that no cables are pinched under the cover.

To calibrate the entry/exit port, follow these steps:
1.
1.1.
1. Open the library’s door and make sure that the calibration cartridge is
located in the slot immediately above the tape drive bays, as shown in
Figure 6. If necessary, install the calibration cartridge with the target
window toward the front.
2.
2.2.
2. Close the door.
3.
3.3.
3. Connect the power cord and power on the library. Wait for the library and
tape drives to perform their power-on self-tests.
4.
4.4.
4. Orient the entry/exit port caddy with the handle vertical and the alignment
guides toward the top, as shown in Figure 7. The alignment guides fit
through corresponding slots in the entry/exit port. Insert the caddy through
the entry/exit port doors. Slide it in until the front of the caddy is
approximately flush with the library door.
Important Do not remove the calibration cartridge from its slot. If you place the calibration
cartridge in a different slot, library operation may be interrupted or terminated.

Caution When closing the door, push slowly near the latch, not at the top of the door.
Forcing the door closed too quickly or pushing near the top can distort the position
of the cartridge slots mounted on the door.
Important Make sure that the caddy is installed in the entry/exit port so
that its slot positions can be calibrated.
