26 Operation and Maintenance

Note

If you load the cleaning cartridge into the drive after it has exhausted its

cleaning cycles, it will not clean the head (the cycle is noticeably shorter) and

the Use Cleaning TapeUse Cleaning Tape LED will be illuminated. Be sure to replace the cleaning

cartridge when the cleaning cycle is noticeably shorter.

Cleaning the Enclosure

The outside of the enclosure can be cleaned with a damp towel. If you use a liquid all-purpose cleaner, apply

it to the towel. Do not spray the enclosure.

Power Supplies

Introduction

The T5 comes with two "hot-swappable" 300-watt power supplies. Each auto-sensing (90 to 230 VAC, 50 to

63 Hz) supply provides operating voltages of +5 V @ 30 A and +12 V @ 14 A. Either supply will power the

chassis in the event that the other ceases to function. This is particularly important for DLT

drives since

data loss can occur as a result of a power failure. Under nominal operating conditions both power supplies

provide approximately half of the chassis power, which results in extending each power supply’s mean-time-

between-failure (MTBF) rating.

The power supplies are located at the rear of the T5 chassis. If either supply needs replacement, the entire

power supply assembly should be unplugged and replaced.

Power Supply Operation

The T5 provides dual redundant power supplies, either of which can power the T5 chassis and its installed

DLT drives. The power supplies normally operate in parallel and are controlled by proprietary power control

and sharing circuits. In the event of a power supply failure, the surviving supply immediately assumes the full

chassis load.

The T5 power supplies are "hot-swappable" and can be individually removed or replaced while the system is

operating. If a power supply fault occurs, or if a supply is removed or turned off, the corresponding indicator

will extinguish.

Note

Do not operate the system with only a single power supply for any longer than

is absolutely necessary. Doing so will not jeopardize the T5 in any way but it

does leave all data stored on the currently loaded tapes subject to becoming

unavailable.

Power supply removal requires only the unfastening of three captive retaining screws. Pulling straight out on

the handle will then de-couple the docking connectors and allow the supply to be taken directly out of the

chassis.
