INSTALLATION
2.2 Electrical Installation for Chassis
With a built-in AC power chassis, AC power is supplied to the chassis through a standard IEC C14 3-prong
receptacle, located on the rear of the chassis. Any detachable nationally approved power cord with IEC C13 line plug
may be used to connect AC power to the chassis unit. With a built-in DC power chassis, DC-48V is connected to the
terminal block located on the rear of the chassis, observing the proper polarity. The chassis should always be
grounded through the protective earth lead of the power cable in AC installations, or via the frame ground connection
for DC installations.

2.3 Installation of SFP Modules
This device supports SFP modules that are of the Bale Clasp type. The bale clasp pluggable module has a bale
clasp that secures the module into the SFP cage.
2.3.1 Inserting a Bale Clasp SFP Module into the Cage
Step 1. Close the bale clasp upward before inserting the pluggable module.
Step 2. Line up the SFP module with the port, and slide it into the cage.
2.3.2 Removing a Bale Clasp SFP Module
Step 1. Open the bale clasp on the SFP module. Press the clasp downward with your index finger.
Step 2. Grasp the SFP module between your thumb and index finger and carefully remove it from the SFP cage.
