Opening the Base Cabinet

The lid on the Base Cabinet is held in place by two tabs that rest in slots in the bottom

of the case, and a release tab that snaps into an opening in the top-center of the

cabinet and is secured by a retaining screw.

To remove the lid:

1. Remove the retaining screw and depress the release tab at the top of

the cabinet.

2. Rock the lid back from the top.

3. Lift and pull the lid free from the slots in the bottom of the cabinet.

Mounting the Base Cabinet

To mount the ESI-50 Base Cabinet, use the three provided #8 Phillips screws. Note the position of the three

mounting holes in the cabinet. Allow room for installation of the Expansion Cabinet (see “Expansion Cabinet”

installation, below) either now or, if required, in the future.

1. Screw in the top screw to the backboard (at least half-inch thick

plywood) leaving about one-eighth-inch clearance between the

screw head and the plywood.

2. Hang the unit using the keyhole at the top of the case.

3. Level the unit and install the bottom two screws.

Attach the power transformer to the wall, allowing sufficient length in both cords to

reach the power connector on the upper right side of the cabinet and to reach a UPS

or a dedicated 110 VAC outlet.

Expansion Cabinet installation

The Expansion Cabinet allows the ESI-50L’s capacity to grow by up to two additional port cards. The cards are

connected via ribbon cables, through the opening in the back of the Expansion Cabinet, to the Base Cabinet.

Note: You can add only one Expansion Cabinet to an ESI-50L.

To install an Expansion Cabinet:

1. Wear a grounding strap and avoid unnecessary movement while handling

the circuit boards.

2. Unplug the power to the ESI-50L system.

3. Remove the Base Cabinet lid by pressing the release tab at the top of the

cabinet and rock back the lid from the bottom of the cabinet.

4. Install the Expansion Cabinet on the front of the Base Cabinet in place of the

Base Cabinet's lid.

5. Lock the Expansion Cabinet to the Base Cabinet by snapping the top in place

and reinstalling the retaining screw.

6. Connect the grounding strap from the Expansion Cabinet's grounding lug

(located on the bottom of the cabinet) to the Base Cabinet's grounding lug.

(See also “Grounding instructions,” page G.1).

7. Through the large opening in the back of the Expansion Cabinet, connect the

ribbon cable(s) from the port card(s) to the card directly below.

8. Re-install the original lid from the Base Cabinet on the face of the

Expansion Cabinet.
