Preparation
2.1 Site Selection
The following criteria should be considered when selecting a site to install the switch:
• Temperature and Ventilation: For prope r ve ntila tion, insta ll the switch whe re the re is ample
airflow to the front and back of the switch. The ambient temperature should not go below 0° or
exceed 40° C.
Impo rt a n t ! To pre ve nt the s witch from ove rhe a ting, do not ope rate it in a n a rea whe re the ambie nt te mpe rature
exceeds 40°C (104°F).
• Airflow Orientation: Determine the airflow direction of the four fan modules and two power s upply
modules on the rear panel. Figure 2-1 on page 6 indicate s the loca tion of the a irflow dire ction la be l
on the power supply modules. The fan module airflow direction label is located on the left side of
the handle. The fan and power supply module handles also indicate the module airflow direction:
• Blue Handle: Air Inlet module.
• Red Handle: Air Exit module.
Verify that each module has the same airflow direction. Base the switch orientation on the airflow
direction of the modules to assure the air inlet is always oriented toward the cool aisle:
• Air Exit modules : orie nt the rea r pa ne l towa rd the hot ais le.
• Air Inlet modules: orie nt the rea r panel towa rd the cool a isle .
If the a irflow dire ction is not compa tible with the insta llation s ite, conta ct your sale s repre se nta tive
to obtain modules that circulate air in the opposite direction.
• Rack Space: Ins ta ll the s witch in a 19" ra ck or ca bine t. The s witch he ight is 1 RU. The a cce ss ory
kit provides mounting brackets for two-post and four-post racks.
When mounting the switch in a partially fille d ra c k, loa d th e ra c k fro m b o tto m to to p, with th e
he a vie s t equipme nt a t the bottom. Loa d the s witch a t the bottom if it is the only ite m in the ra ck.
• Power Requirements: The s witch re quire s one of the se circuits :
• 100-240 VAC, 5.29-2.2 A, 50-60 Hz A.
• 40-72 VDC, 13.9–7.72 A.
Two circuits provide redundancy protection. Section 4.1 describes power cable requirements.
