SAFETY GUIDELINES

The safety guidelines (see Chapter 1: “Safety Guidelines” on page 1-iv) are provided to help ensure your safety and to protect your equipment. The list on page iv may not identify all potentially hazardous situations in your working environment, so be alert and exercise good judgment at all times.

Each HMS-318 List 3 shelf has a hardware kit. The rack adapter brackets are attached to the HMS-318 List 3 shelf at the factory. They are supplied with the shelf to allow mounting on 19-inch (48.3-cm) telco-style EIA or WECO equipment racks. Select the appropriate position for the brackets (2 or 5 inches) and mount the shelf to the bracket as described in the Chapter 2: “Adapter Bracket Mounting Procedure (19-inchTelco-style Equipment Rack)” on page 2-5and the Chapter 2: “Adapter Bracket Mounting Procedure (23-inchTelco-style Equipment Rack)” on page 2-5. When installed in an EIA rack, a total of three 1.75-inch (4.4-cm) mounting spaces [5.25 inches (13.3 cm) of vertical rack space] are required for mounting an HMS-318 List 3 shelf. When installed in a WECO rack, a total of three 2.0-inch (5.08-cm) mounting spaces [6 inches (15.2 cm) of vertical rack space] are required for mounting.

ETSI adapter brackets are included for installation of the HMS-318 List 3 shelf in an ETSI-style equipment rack (see Chapter 2: “Adapter Bracket Mounting Procedure (ETSI-style Equipment Rack)” on page 2-6).

IMPORTANT

Clearance above and below the shelf must be allowed for cooling air to be drawn in the front and circulated through the shelf and out. A heat (air) baffle must be used between shelves to ensure that heated air is dissipated appropriately (see “Air Flow Guidelines” on page 21 for detailed information about air flow guidelines).

Special Rack-Mounting Precautions

Special rack-mounting precautions must be followed to ensure safety. They are:

•Never wear loose clothing, jewelry (such as rings, bracelets, or chains), or other items that could get caught in the shelf housing during handling and use.

•When mounting the shelf to a telco-style rack, ensure that the rack is bolted to the floor.

•Since you will probably be installing more than one shelf into the rack, ensure that the weight of all the shelves installed does not make the rack unstable.

IMPORTANT Some telco-style racks are also secured to ceiling brackets, if necessary, due to the weight of the

!equipment in the rack. Make sure that the rack you are using to install the shelves is secured to the building structure.

•As mentioned in “Air Flow Guidelines” on page 1-15, maintain a clearance of 6 inches (15.2 cm) at the front and back of the shelf to ensure adequate air intake and exhaust.

•Avoid installing the shelves in an overly congested rack (see “Heat Dissipation Factors” on page 1-13). Air flow- ing to or from other shelves in the rack might interfere with the normal flow of cooling air through the shelves, increasing the potential for over temperature conditions within the shelves.

•Allow at least 19 inches (48.7 cm) of clearance at the front and back of the rack for shelf maintenance.

•Follow your local practices for cable management. Ensure that cables to and from the shelves do not impair access to perform equipment maintenance or upgrades.
