Chapter 2 Preparing to Install the Cisco MXE 3000

Environmental Requirements

Working Inside the Cisco MXE 3000 with the Power On

The Cisco MXE 3000 is designed to operate safely with the cover removed for short periods (less than

minutes). You might need to remove the cover while the power is on, for example, to observe the

diagnostic LEDs when troubleshooting. When you work inside an appliance that is powered on, follow

these guidelines:

• Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the

appliance; do not wear cuff links while you are working inside the appliance.

• Do not allow your necktie or scarf to hang inside the appliance.

• Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wristwatches.

• Remove items from your shirt pocket (such as pens or pencils) that could fall into the appliance as

you lean over it.

• Do not drop any metallic objects, such as paper clips, hairpins, or screws, into the appliance.

• Be aware that there are hazardous moving parts exposed inside the appliance when the cover is

removed.

Protecting Against Electrostatic Discharge

Static electricity can harm delicate components inside the appliance. To prevent static damage, discharge

static electricity from your body before you touch any of your system’s electronic components. You can

do so by touching an unpainted metal surface on the chassis.

You can also take the following steps to prevent damage from electrostatic discharge (ESD):

• When unpacking a static-sensitive component from its shipping carton, do not remove the

component from the antistatic packing material until you are ready to install the component in your

system. Just before unwrapping the antistatic packaging, be sure to discharge static electricity from

your body.

• When transporting a sensitive component, first place it in an antistatic container or packaging.

• Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and

workbench pads.

• Handle the device carefully, holding it by its edges or its frame.

• Do not touch solder joints, pins, or exposed printed circuitry.

• Do not leave the device where others can handle and possibly damage the device.

• Take additional care when handling devices during cold weather, because heating reduces indoor

humidity and increases static electricity.

Environmental Requirements

To ensure continued safe and reliable equipment operation, install or position the system in a

well-ventilated, climate-controlled environment.

The maximum recommended ambient operating temperature (TMRA) for most server products is 35°C

(95°F). The temperature in the room where the rack is located must not exceed 35°C (95°F).
