Site Requirements
The environmental monitoring in the router protects the system and components from potential
damage from overvoltage and overtemperature conditions. To assure normal operation and avoid
unnecessary maintenance, plan your site configuration and prepare your site before installation.
After installation, make sure the site maintains an ambient temperature of 32°F through 104°F (0°C
through 40°C), and keep the area around the chassis as free from dust as is practical.
The following sections address the site environment requirements for the router.

AC and DC Power

The 550W, wide-input, AC-input power supply uses a power factor corrector (PFC) that allows it to
operate on input voltages between 100 an 240 VAC and 50 through 60 Hz. Table 1-2 lists system
power specifications, including input voltage and operating frequency ranges. Install a power
conditioner between the AC line input and the router to help avoid network outages caused by power
spikes and brownouts, and to help protect against equipment damage from lightning strikes. The
600W, DC-input power supply allows the Cisco 7010 to operate between –40 and –52 VDC
(–48 VDC nominal). In the European Community, the power supply operates between –56 VDC and
–72 VDC (–60 VDC nominal).

Plant Wiring

Following are guidelines for setting up the plant wiring and cabling at your site. When planning the
location of the new system, consider the distance limitations for signaling, electromagnetic
interference, and connector compatibility, as described in the following sections.
2-4 Cisco 7010 Hardware Installation and Maintenance
Handle interface processors by the handles and carrier edges only; avoid touching the board or
any connector pins.
When removing an RP, SP (or SP), interface processor, or the arbiter, place the removed
component board-side-up on an antistatic surface or in a static shielding bag. If the component
will be returned to the factory, immediately place it in a static shielding bag.
Handle bare boards (such as the arbiter board) by the edges only.
Avoid contact between the board or interface processor and clothing. The wrist strap only
protects the card from ESD voltages on the body; ESD voltages on clothing can still cause
damage.
For safety, periodically check the resistance value of the antistatic strap. The measurement
