Sections include: · Battery Backup Unit Specifications · Battery Backup Kit Contents Introduction 1-1 1.1 Battery Backup Unit Specifications The battery backup unit (BBU) is installed adjacent to the H405 AC power controller. If the system has imbedded storage in one slot, install the BBU next to the SA70. Figure 1-1: Battery Backup Unit Location 1-2 VAX 6000: Installing the H7236-A Battery Backup Option The H7236-A BBU is a new battery backup unit for the VAX 6000 series. It can be installed in an XMI-2 VAX 6000 (cabinet number H9657-CA/CB) or in a Model 200, 300, or 400 that has been upgraded to a Model 500 using the full power and packaging upgrade kit H9657-CU. If the H405 AC power controller is not at the required revision (see Table 2-1), it must be replaced. NOTE: If an earlier model has been upgraded to a Model 500 using the H9657-CX upgrade kit, battery backup is not supported. The BBU will not provide backup power for an expander cabinet configuration. The H7236-A provides system ride-through capabilities for power losses of up to one second. Momentary lapses in power, therefore, have no effect on the system. For power losses greater than one second, the BBU provides power for up to 10 minutes to the entire XMI side of the system. If power does not return after one second, an orderly shutdown of the VAXBI side is initiated. The caches are then flushed and memory is saved. If power is returned within 10 minutes, the system performs a warm restart. Table 1-1 lists the battery backup unit specifications.

Chapter 3 discusses the BBU self-test, indicators, and switches. Battery Backup Unit Installation 2-19 Chapter 3 Battery Backup Unit Indicators and Switches ------------------------------------------------------------ This chapter discusses the battery backup unit's indicators and switches. Sections include: · Battery Backup Unit Indicators · Battery Backup Unit Switches Battery Backup Unit Indicators and Switches 3-1 3.1 Battery Backup Unit Indicators The H7236-A battery backup unit has five LED indicators on the lower righthand corner of the front of the unit. Figure 3-1: BBU Indicators (Rear View) 3-2 VAX 6000: Installing the H7236-A Battery Backup Option Table 3-1 describes the five LEDs of the H7236-A. Refer to Figure 3-1 for LED numbering. Table 3-1: H7236-A Indicators ------------------------------------------------------------ LED Color On indicates: ------------------------------------------------------------ L1 Green Batteries supplying power. L2 Green BBU CHARGE. On steady when BBU charged to at least 98%. Blink- ing at 1 Hz when charging but less than 98% charged. Blink- ing at 10 Hz when BBU needs service. L3 Red OVER TEMP. Blinking when the external ambient temperature has ex- ceeded 40 degrees C or the BBU fan has failed while the BBU is sup- plying power. L4 Red ELECTRONIC FAIL. On steady when BBU detects an error re- lated to its electronics. L5 Red BATTERY SERVICE. Blinking at 1 Hz when battery has less than 40% original capacity or when BBU has failed. On steady when BBU has de- tected a disconected battery or an open front cover inter- lock switch on self-test. ------------------------------------------------------------ LEDs 3 and 5 are latched on to indicate BBU faults. You reset these LEDs by pressing the Alarm Reset switch inside the H7236-A (see Figure 3-2). When the system is powered up, the BBU automatically initiates self-test. During self-test, which is completed within 60 seconds, the five LEDs cycle in a sequential pattern. Battery Backup Unit Indicators and Switches 3-3 3.2 Battery Backup Unit Switches The H7236-A battery backup unit has six switches: two external switches are visible at the rear of the unit, and four internal switches are visible when the fan housing is removed from the front of the unit. Figure 3-2: Internal BBU Switches (Front View) 3-4 VAX 6000: Installing the H7236-A Battery Backup Option The two external switches are the voltage selection switch and the AC power switch, visible at the cabinet rear (see Figure 3-1). NOTE: Switch the AC power switch (toggle switch) Off when you are removing or installing the BBU option. Before power-up, set the voltage selection switch to the proper value for the system (115V at 60 Hz or 230V at 50 Hz). The four internal switches (see Figure 3-2), which are visible at the front of the unit when the fan housing is removed, are: · Fan Panel Interlock Switch -- Shuts down the BBU when the fan housing cover is removed. See !. · Alarm Reset Switch (pushbutton switch) -- Resets either of the two latched alarm conditions (OVERTEMP, L3, and BATT SERVICE, L5). See ". · Battery Life Switch (toggle switch) -- Activates the battery life enhancement mode, which provides a longer battery life in return for a reduction in the available reserve time at the start of the operation. The BBU normally runs in battery life enable mode. See #. · New Battery Reset Switch (pushbutton switch) -- Resets the battery aging information in the EEPROM. This switch is activated only when the battery pack is replaced with a new one. The battery life switch must be in the Enable position for this switch to function. See $. For BBU service information, refer to the VAX 6000 Platform Service Manual.
