Chapter 2. Removal and replacement procedures

This chapter describes how to remove and replace the field replacement parts. It is

supplemental to the common installation and replacement procedures in SurePOS

700 Series SurePOS 700-723/743/783/784 Systems, Installation, and Operations

Guide, GA27-4998.

Before you begin

Before you begin any of the procedures in this chapter, complete the following

steps:

1. Turn the power OFF at the system unit.

2. Disconnect the power cord from the external power source.

CAUTION:

Never attempt to service this product with AC power present. Only apply

AC power after the system is fully assembled.

3. Remove any attached devices and I/O connections from the unit.

4. Establish personal grounding before touching the unit. For more information,

see “Federal Communications Commission statement” on page 95.

Attention: Before servicing the inside of the system and after you have slid out

the pullout tray from the unit frame, verify that no system board LEDs (red) are

illuminated. Any illuminated LED indicates the presence of power; you must remove

the AC power cord before continuing.

Cables, connectors, and headphones

These tips will assist you when removing and replacing parts for the SurePOS 700:

v All cables and connectors are keyed; therefore, you cannot insert a cable in an

incorrect location.

v When connecting a powered USB cable to the back of the unit, insert the

connector with the latch on the bottom. A bottom latch makes it easy to

disconnect. For the front USB cables, insert the connector in the usual manner,

with the latch on the side.

v For Models 743, C43, E43, 783, E83, 784, C84, and E84, installing a headphone

overrides the line-out speaker.

v All models contain a serial ATA (SATA) connector.

v When routing the cables in the rear, leave extra length at the connector end by

forming a loop before attaching the cable into the cable guide. This extra length

prevents undue strain on the connector.

Removing the slanted I/O tray

The slanted I/O tray installs on the top of a wide system unit and groups the IBM

printer and keyboard with specific dimensions. The tray has a raised edge that is

low in the front. The sides slope up toward the rear and are higher at the rear than

at the front.
