Chapter 2 Preparation

2.1 Site Selection

The following criteria should be considered when selecting a site to install the switch:

•Floor Space: Install the switch in an area that provides adequate clearance for removing front and

rear components. Figure 1 displays switch clearance requirements.

•Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow

to the front and back of the switch. The temperature should not go below 0° or exceed 40° C.

Important! To prevent the switch from overheating, do not operate it in an area where the ambient temperature

exceeds 40°C (104°F).

•Airflow Orientation: The fans direct air from the front panel to the rear panel. Orient the front

panel toward the cool aisle.

•Rack Space: Install the switch in a 19" rack or cabinet. The switch height is 11 RU (7508 / 7508E) or

7 RU (7504 / 7504E). The accessory kit provides mounting brackets for two-post and four-post racks.

When mounting the switch in a partially filled rack, load the rack from bottom to top, with the

heaviest equipment at the bottom. Load the switch at the bottom if it is the only item in the rack.

•Power Requirements: The 7508 / 7508E switch requires two 200-240 VAC, 50 or 60 Hz, 20 A circuits.

The 7504 / 7504E switches require one 200-240 VAC, 50 or 60 Hz, 20 A circuit.

Four circuits provide redundancy protection. The switch uses power cables that comply with

IEC-320 and have a C19 plug. The accessory kit provides four IEC-320 C19 to C20 power cables, each

two meters long.

Important! All power input plug-socket combinations must be accessible at all times; they provide the primary

method of disconnecting power from the system.

•Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and

foreign objects are not drawn into the ventilation holes. Verify these guidelines are met:

— Clearance areas to the front and rear panels allow for unrestricted cabling.

— All front and rear panel indicators can be easily read.

— AC power cords can reach from the AC power outlet to the connectors on the front panel.

Important! Disconnecting power to all input sockets is required to completely power off the unit.

2.3 Electrostatic Discharge (ESD) Precautions

Observe these guidelines to avoid ESD damage when installing or servicing the switch.

• Assemble or disassemble equipment only in a static-free work area.

• Use a conductive work surfaces (such as an antistatic mat) to dissipate static charge.

• Wear an ESD wrist strap to dissipate static charge accumulation.

• Minimize handling of assemblies and components.

• Keep replacement parts in their original static-free packaging.

• Remove all plastic, foam, vinyl, paper, and other static-generating materials from the work area.

• Use tools that do not create ESD.

7500 Series Modular Switch Quick Start Guide PDOC-00015-07 7

Chapter 3 Rack Mounting the Switch

The accessory kit provides components for installing the switch in two-post and four-post racks.

•Section 3.1 provides instructions for mounting the switch in a two-post rack.

•Section 3.2 provides instructions for mounting the switch in a four-post rack.

The rack mounting procedure is identical for all modular switches. Illustrations in this chapter depict

the mounting of an unpopulated DCS-7508 chassis.

After completing the instructions for your rack type, proceed to Chapter 4.

3.1 Two-Post Rack Mount

To mount the switch to a two-post rack, assemble mounting brackets to the middle of the chassis, then

attach the brackets to the rack. The switch does not support a front or rear mount into a two-post rack.

The accessory kit includes the following two-post mounting parts:

•2center-mountbrackets

• 20 M4x8 panhead Phillips screws

Figure 23 displays the two-post mounting parts.

3.1.1 Attaching Mounting Brackets to the Chassis

Step 1 Orient the switch chassis and the two center-mount brackets (Figure 2).

Position the flanges that attach to the rack posts toward the rear of the chassis.

Step 2 Attach both center-mount brackets to the chassis.

Each bracket requires ten M4x8 panhead Phillips screws.

Figure 2: Attaching the Center-mount Brackets

Chapter 3: Rack Mounting the Switch

3.1.2 Inserting the Switch into the Rack

Step 1 Move the chassis to the rack using a mechanical lift (Figure 3).

If modules are inserted in the chassis, use the lift carefully to avoid damaging any components.

Step 2 Lift the chassis into the rack. Position the flanges against the rack posts (Figure 3).

Step 3 Select mounting screws that fit your equipment rack.

A minimum of four screws is required on each side of the chassis. The accessory kit provides

screws that fit many common equipment racks. When installing the switch into a rack with

unthreaded post holes, nuts are also required to secure the switch to the rack posts.

Step 4 Attach the bracket flanges to the rack posts (Figure 4). Space the screws evenly along the flange.

After completing the two-post installation, proceed to Chapter 4.

3.2 Four-Post Rack Mount

The switch is mounted onto a four-post rack by assembling a shelf into the rack, then placing the switch

on the shelf.
