Installation Overview 3 This chapter contains an overview about how to install the uninterruptible power supply (UPS) optional feature for the L180 and L700 Tape Libraries. Note: Always refer to the instructions sent with the feature for specific information about how to install the UPS.
Installation Overview Rear Door Replacement Some early model library rear doors are not compatible with the optional rack cooling feature. Check the serial number of your library, if it falls within the ranges listed, you need to replace the rear door. The following table lists the serial number range, description, and field bill number for the rear door.
Installation Overview ■ Instructions The following is an overview of the installation procedure to install the UPS in the L180 and L700 Tape Libraries: 1. Open the front door. 2. Open the rear door. Note: You can remove the doors for ease of installation. 3. Power-off the library and all the tape drives. 4. Unpack the UPS, redundant switch, mounting hardware, and documentation. 5. Install the rail kits for the UPS in the rack area.
Installation Overview 8. Connect the Ethernet cables to each UPS. 9. Connect the serial port cables to the connectors on the rear of the UPS. 10. Using the rack-mount hardware, install the switch above UPS A. Figure 3-2. Rear Connections OUTLET STRIP REDUNDANT SWITCH UPS A ETHERNET CABLES UPS B SERIAL PORT CABLE A SERIAL PORT CABLE B C67335 Note: See Figure 3-3 on page 3-5 for a block diagram of the cable routing and connections. 11. Connect the UPS serial port cables to the switch. 12.
Installation Overview c. Turn-on (to the right) the two circuit breakers on the rear of the switch (Load 1 and Load 2). d. Press the power button on the front of the outlet strip. 19. Make sure all components (library, tape drives, fans, and UPS) are on. 20. Follow the directions on the APC publication, WEB/SNMP Management Card, Installation and Quick Start Manual to configure the TCP/IP settings. This document and a CD-ROM are provided in the UPS packaging.
Installation Overview ■ APC Web/SNMP Management Card The APC AP9606 Web/SNMP management card is a web-based management tool that allows you to monitor and configure the UPS. The card conforms to open communication standards such as Telnet, HTTP, and SNMP. The client software requirements include standard Web browsers such as Microsoft Internet Explorer and Netscape Navigator Versions 4.0 and above.
Installation Overview Voltage Sensitivity When the UPS detects distortions with the input power (by default), it reacts by transferring the UPS to battery operation to protect the loads. Also, when the quality of the power is poor, the UPS may frequently transfer to on-battery operation. If the loads can operate normally under such conditions, the capacity of the battery and service life may be conserved by reducing the sensitivity of the UPS.

Fault Isolation ■ View Event Log The following screen shows an example of the event log. The Event Log stores past events including information that will help troubleshoot intermittent or site specific power problems.
Fault Isolation ■ Troubleshooting the UPS Table 4-1 describes some possible problems and solutions when troubleshooting the UPS: Table 4-1. Troubleshooting the APC Uninterruptible Power Supply Problem and Possible Cause Solution UPS will not turn on. • ON button not pushed. Press the ON button once to power on the UPS and other equipment. • UPS not connected to AC power supply. Make sure the power cable from the UPS to the customer’s input power is securely connected at both ends.
Fault Isolation Problem and Possible Cause Solution UPS does not provide expected backup time. • The UPS’s battery is weak because of a recent power outage or is near the end of its service life. Charge the battery. Batteries require recharging after extended outages. The batteries wear faster when in service more often and when operated at higher temperatures. If the battery is near the end of its service life, consider replacing the battery. Contact StorageTek’s Customer Support Services.
Fault Isolation ■ Battery Replacement The following procedure explains how to replace a worn or weak battery in the UPS. Observe the following safety precautions before replacing the battery. Battery Safety Observe the following safety precautions when replacing the batteries: WARNING: Personal injury. Do not lift heavy loads without assistance. The batteries are heavy and require two people to lift and install them. • The UPS contains potentially hazardous voltages.
Fault Isolation 2. Remove the two (2) screws from the battery door with a Phillips screwdriver and remove the battery door. 3. Disconnect the leads from the battery. Pull the connectors towards you to disconnect the battery. 4. Use a Phillips head screwdriver to remove the screws that secure the battery tray. Set the screws aside. WARNING: Personal injury. The batteries are heavy. Use two people to remove the battery from the UPS. 5. Use the battery tray handle to slide the tray out about halfway. 6.
