Setting Up the Matrix E7 Chassis
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 Matrix E7 power supplies must be installed in the two slots labeled PS1 and PS2 at the bottom
of the chassis (Figure
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 Matrix E7 chassis, refer to
1. Unpack the power supply by removing it from the shipping box and sliding the two foam end
caps off the unit. (Save the shipping box and materials in the event the unit must be reshipped.)
2. Remove the power supply from its protective plastic bag. (Save the shipping box and materials
in the event the unit must be reshipped.)
3. Examine the power supply carefully, checking for damage. If any damage is noted, DO NOT
install the power supply. Contact Enterasys Networks immediately.
4. Slide the power supply into the slot labeled PS1 as follows:
a. Hold the power supply by placing one hand on the handle located on the front panel and using
the other hand to support the power supply.
b. Holding the power supply right side up, align the power supply with the plastic guides on the
bottom of the opening.
CAUTION: Forcing a misaligned power supply into place can damage the power supply
and/or the chassis backplane.
c. With the power supply properly inserted into the opening, carefully slide the supply forward
until it is connected to the backplane. The front panel should be flush with the face of the
Matrix E7 chassis. If significant resistance is encountered before the front panel is flush,
remove and reinsert the power supply. Do not force the power supply into place.
d. Secure the power supply to the chassis by using a large flat blade screwdriver to turn the large
screw and lock the power supply in place.
5. If you are installing a second power supply, remove the blank plate from the second power
supply slot (keep the blank plate in the event you need to remove the power supply), and repeat
steps 1– 4.
