Setting Up the Enterasys Matrix N7 Chassis
Enterasys Matrix N7 Chassis Setup 3-11
3.2.3.3 Attaching the Electrostatic Discharge Wrist Strap
The Electrostatic Discharge (ESD) wrist strap must be attached before handling the power
supplies, fan tray, and modules used in the N7 chassis. In addition, observe all precautions when
handling these modules to prevent damage from electrostatic discharge.
Place the ESD wrist strap on your wrist and plug the other end into the grounding receptacle, at the
top right corner of the chassis, shown in Figure 3-6.

3.2.4 Installing a Power Supply
You must install at least one 7C203-1power supply in the Enterasys Matrix N7 chassis. One power
supply provides sufficient power for a fully loaded chassis, but a second power supply can be
installed to provide a redundant, load sharing power source. When you receive your N7 chassis a
cover plate will be in place over power supply slot PS2.
When two power supplies are installed, the load is evenly distributed. If one power supply fails for
any reason, the second power supply assumes the load.
The power supplies must be installed in the two slots labeled PS1 and PS2 at the bottom of the
chassis (Figure 3-7). If you intend to install a single power supply, it must be installed in the slot
labeled PS1 in the chassis. A large flat blade screwdriver is needed to install the power supplies.
To install the power supply into the Enterasys Matrix N7 chassis, refer to Figure 3-7 and proceed
