Safety instructions

Use the following safety guidelines to protect your computer from potential damage and to ensure your personal safety. Unless otherwise

noted, each procedure included in this document assumes that the following conditions exist:

• You have read the safety information that shipped with your computer.

• A component can be replaced or, if purchased separately, installed by performing the removal procedure in reverse order.

WARNING: Disconnect all power sources before opening the computer cover or panels. After you nish working inside the

computer, replace all covers, panels, and screws before connecting to the power source.

WARNING: Before working inside your computer, read the safety information that shipped with your computer. For additional

safety best practices information, see the Regulatory Compliance Homepage at www.Dell.com/regulatory_compliance

CAUTION: Many repairs may only be done by a certied service technician. You should only perform troubleshooting and simple

repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage

due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came

with the product.

CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an

unpainted metal surface at the same time as touching a connector on the back of the computer.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its

edges or by its metal mounting bracket. Hold a component such as a processor by its edges, not by its pins.

CAUTION: When you disconnect a cable, pull on its connector or on its pull-tab, not on the cable itself. Some cables have

connectors with locking tabs; if you are disconnecting this type of cable, press in on the locking tabs before you disconnect the

cable. As you pull connectors apart, keep them evenly aligned to avoid bending any connector pins. Also, before you connect a

cable, ensure that both connectors are correctly oriented and aligned.

NOTE: The color of your computer and certain components may appear dierently than shown in this document.

CAUTION: System will shut down if side covers are removed while the system is running. The system will not power on if the side

cover is removed.

Turning o your computer — Windows 10

CAUTION: To avoid losing data, save and close all open les and exit all open programs before you turn o your computer or

the network device.

5 Disconnect your computer and all attached devices from their electrical outlets.

6 Press and hold the power button while the computer is unplugged to ground the system board.

NOTE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an

unpainted metal surface at the same time as touching a connector on the back of the computer.

After working inside your computer

After you complete any replacement procedure, ensure that you connect any external devices, cards, and cables before turning on your

computer.

1 Connect any telephone or network cables to your computer.

CAUTION: To connect a network cable, rst plug the cable into the network device and then plug it into the

computer.

2 Connect your computer and all attached devices to their electrical outlets.

3 Turn on your computer.

4 If required, verify that the computer works correctly by running ePSA diagnostics.

Teradici PCoIP

This section provides an overview of the host driver installation process.

Installing the Teradici PCoIP Card Host Dual/Quad

Install the PCoIP host driver software from dell.com/support.

66 Technology and components

NOTE: You cannot upgrade the PCoIP host driver software while a VMware View-brokered PCoIP session is active between a

host workstation or host PC and VMware View client. Doing this will result in losing access to your mouse and keyboard when the

driver software is removed.

To upgrade the PCoIP host driver software in this type of deployment, do one of the following:

• Connect to the host from a zero client.

• Upgrade the software while connecting to the host through another desktop-remoting protocol such as RDP or VNC.

Installing the PCoIP Host Driver Software on a Host PC:

1 Download the PCoIP host driver software from the Teradici Support site (click Current PCoIP Product and Releases).

2 Log in to the administrative web interface for the host card.

3 From the Conguration > Host Driver Function menu, enable the Host Driver Function.

4 Restart the host PC.

5 Install the PCoIP host software package appropriate for the operating system installed on the host PC. You can start the install

process by double-clicking the installer:

a 64 bit: PCoipHostSoftware_x64-v4.3.0.msi (or later)

6 When the Welcome screen appears, click Next.

7 Accept the terms, and then click Next.

8 Ensure that the installation location is correct, and click Next.

9 Click Install.

NOTE:

For Windows 7, when the driver is installed, a Windows Security dialog may appear. Click Install to continue with the

installation. To keep this dialog box from appearing in the future, select Always trust software from Teradici Corporation.

10 If prompted, restart the operating system; otherwise, skip this step. When restarted, the host driver software installation process

continues when the OS boots up. Click Install to continue.

11 Click Finish to complete the installation.

Flashing the BIOS from the F12 One-Time boot menu

Updating your system BIOS using a BIOS update .exe le copied to a FAT32 USB key and booting from the F12 one time boot menu.

BIOS Update

You can run the BIOS update le from Windows using a bootable USB key or you can also update the BIOS from the F12 One-Time boot

menu on the system.

Most Dell systems built after 2012 have this capability and you can conrm by booting your system to the F12 One-Time Boot Menu to see

if BIOS FLASH UPDATE is listed as a boot option for your system. If the option is listed, then the BIOS supports this BIOS update option.

NOTE: Only systems with BIOS Flash Update option in the F12 One-Time Boot Menu can use this function.

Updating from the One-Time Boot Menu

To update your BIOS from the F12 One-Time boot menu, you will need:

• USB key formatted to the FAT32 le system (key does not have to be bootable)

• BIOS executable le that you downloaded from the Dell Support website and copied to the root of the USB key

• AC power adapter connected to the system

• Functional system battery to ash the BIOS

Perform the following steps to execute the BIOS update ash process from the F12 menu:

CAUTION: Do not power o the system during the BIOS update process. Powering o the system could make the system fail to

boot.

1 From a power o state, insert the USB key where you copied the ash into a USB port of the system .

2 Power on the system and press the F12 key to access the One-Time Boot Menu, Highlight BIOS Flash Update using the arrow keys

then press Enter.
