PartI
Installing the System
Part I contains all of the information that you need to install the DECNIS 600:
• Chapter 1 describes the preparations you need to make before installing
the DECNIS 600 unit.
• Chapter 2 shows how to install the DECNIS 600.
• Chapter 3 shows how to install Network Interface Cards into a system that
is powered down.
• Chapter 4 shows how to power up and test the installed system.
Preparing to Install the System
This chapter describes the preparations you need to make before installing the DECNIS 600.
1.1 Tasks
Follow the procedures in Sections 1.2 to 1.6 to:
1. Plan a site for the DECNIS 600.
2. Prepare a rack (or cabinet) for the DECNIS 600.
3. Check that the site fulfills electrical requirements for the DECNIS 600.
4. Check the contents of the kit.
5. Check that you have the necessary tools available.
6. Check that two or more people are available to lift the DECNIS 600 from
its packaging and into the rack.
1.2 Planning a Site
1
Before you start the installation, plan and prepare the site for the DECNIS 600 so that:
• The site fulfills all electrical and environmental requirements for the
DECNIS 600. Appendix B describes these requirements.
• A rack is available and all rack requirements are fulfilled. Section 1.3
describes these requirements.
• The correct length of cabling is available for connecting the DECNIS 600 to
other equipment, for example, a modem.
• The site can accommodate plans to expand the system. For example, if
you require a Network Interface Card that uses a distribution panel, you should allow room for the distribution panel in the rack or in a rack nearby.
Preparing to Install the System 1–1
The dimensions of a Network Interface Card and its distribution panel (if used) are specified on the Cabling Instructions and Specifications card. The dimensions of the DECNIS 600 are shown in Section B.3.
1.3 Rack Requirements
The rack that you use for the DECNIS 600 must fulfill the requirements in Section 1.3.1 to Section 1.3.4.
1.3.1 Dimensions
The DECNIS 600 can be installed in one of the following:
• NEP Hard Metric 600 mm rack
• Standard 19 inch rack
For example, the unit can be installed in the Digital H9A00 rack. If you use the DECNIS 600 support brackets that are supplied as part of the
kit, the front and rear mounting rails on your rack or cabinet must be at least
47.63 cm (18.75 in) and no more than 80 cm (31.5 in) apart.
1.3.2 Stability
Make sure that the rack is stable:
• Extend any stabilizers available on the rack.
• If the rack has wheels, take one of the following actions to prevent them rolling:
Jack the rack onto its feet (if available) Apply the brakes (if available) Wedge the wheels Remove the wheels
• If possible, bolt the rack to the floor to prevent it from moving.
1.3.3 Power
If power is available from an outlet in the rack, check that sufficient power is available to the DECNIS 600. Table B–1 shows the power requirements for the DECNIS 600.
If power is available from an outlet outside the rack, for example, a wall socket, check that the power cord from the DECNIS 600 reaches the outlet. The power cord for the DECNIS 600 is 2 m (6.5 ft) long.
1–2 Preparing to Install the System
1.3.4 Access
The following access is required so that the unit can be unpacked and installed:
• Remove any door on the front of the rack, or secure the door open.
• Clear a space of approximately 2 m (6.5 ft) at the front of the rack. You will also need access to the rear of the rack to install the support brackets.
If possible, remove the rear door. If the rear of the rack is against a wall, make sure that you can gain access from the front of the rack.
1.3.5 Position of the DECNIS 600
The DECNIS 600 can be installed in any position in the rack that satisfies the following requirements:
• The position must conform to the published safety standard EN60950,
UL1950, CSA 950. This standard specifies important information about the stability of rack mounted equipment.
• The position must satisfy the environmental requirements specified in
Appendix B.
If other equipment is installed in the rack, you should also check that the DECNIS 600 does not affect the environmental requirements of that equipment. For example, the DECNIS 600 should not be installed in a position that restricts the air flow required for cooling other equipment.
1.4 Kit Contents
Figure 1–1 shows the contents of the kit as they are packed in the DECNIS 600 carton.
When you unpack the DECNIS 600, save the packaging materials and carton in case you need to return any items.
If there are any items missing from the kit, or if any of the contents are damaged, contact your Digital representative.
