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 s witch whe re the re is a mple
airflow to the front and back of the switch. The ambient temperature should not go below 0° or
exceed 40° C.
Impo rtant! 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 re a r pane l towa rd the hot a is le.
•Air Inlet modules: orient the re ar pa ne l 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.
•RackSpace: 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 ck fro m b o tto m to to p , with the
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.
•PowerRequirements: The s witch re quires one of thes e 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.

Tools Required for Installation Preparation
Figure 2-1: Airflow Direction Labels
Impo rtant! The power input plug-socket combination must be accessible at all times; it provides the primary
method of disconnecting power from the system.
•Other Requirements: Select a site where liquids or objects cannot fall onto the equipment and
fore ign obje cts a re not dra wn into the ve ntila tion hole s. Verify the s e guideline s a re me t:
• Cle ara nce a rea s to the front and re ar pane ls a llow for unre stricted ca bling.
• All front and re a r pa ne l indica tors ca n be e a sily re a d.
• Power cords can reach from the power outlet to the connector on the rear panel.
Impo rtant! All power connections must be removed to de-energize the unit.
2.2 Tools Required for Installation
The following tools a nd e quipme nt a re re quire d to ins tall the s witch:
• P hillip s # 1 s c re wd rive r.
• P hillip s # 3 s c re wd rive r.
• Four s crews (two-pos t rack mount) that fit the e quipme nt ra ck.
• Eight s cre ws (four-pos t rack mount) tha t fit the e quipme nt ra ck.
Th e a c c e s s o ry kit do e s no t in clu d e s c re ws fo r s e c ure th e s witc h to th e ra c k. Wh e n in s ta lling th e s witch
into a ra ck with unthre ade d pos t hole s , nuts a re a ls o require d to s ecure the s witch to the ra ck pos ts .
2.3 Electrostatic Discharge (ESD) Precautions
Obs erve the se guideline s to avoid ES D da ma ge whe n ins tallin g o r s e rvicin g th e s witc h .
• As s emble or dis as s emble e quipme nt only in a s ta tic-fre e work are a .
• Use a conductive work surface (such as an anti-static mat) to dissipate static charge.
• Wear a conductive wrist strap to dissipate static charge accumulation.
• Minimize handling of assemblies and components.
• Ke e p replace me nt parts in the ir original static-fre e pa cka ging.
• Re move a ll pla stic, foa m, vinyl, pa pe r, and other sta tic-ge nera ting mate ria ls from the work are a .
• Use tools tha t do not crea te ES D.

Rack Mounting the Switch
Impo rtant! The rack mounting procedure is identical for all switches covered by this guide. Illustrations in this
chapter depict the mounting of a DCS-7124SX switch.
The accessory kit provides components for installin g th e s witc h in two -p o s t a n d fou r-p os t ra cks .
•Se ction 3.1 provides instructions for mounting the switch in a two-post rack.
•Se ction 3.2 provides instructions for mounting the switch in a four-post rack.
Both options require the attachment of mounting brackets to the switch chassis. Each chassis side
conta ins s ix pairs of hole s tha t align with bra cke t hole s. Bra cke t hole orie nta tion is s ymme tric, a llowing
bra cke t pla ce ments whe re the fla nge is flus h with the front or re ar s witch pa ne l (Figure 3-1).

the fus e s.
To connect a DC power supply to power source:
Step 1 Remove the terminal cover to expose the connectors on the right side of the module
(Figure 4-2).
Step 2 Atta ch the appropria te lugs to the s ource DC wire s.
Use DC ca ble s with e ithe r ins ula te d crimp-on s pa de lugs or ins ula ted crimp-on ring
connectors.
Impo rtant! Wire size must comply with local and national requirements and electrical codes. Use only copper wire.
Step 3 Connect the DC-input wires to the terminal block in this order:
1. Ground cable to the ground connector on the terminal block.
2. Negative (–) source DC cable to the negative (–) connector on the terminal block.
3. Positive (+) source DC cable to the positive (+) connector on the terminal block.
Impo rtant! Apply the ground connection first during installation and remove last when removing power.
