Chapter 4: Installation

4.3.2Rackmount Installation

To install the SEHI in a 19-inch rack, Cabletron Systems offers an accessory kit that includes rackmount brackets, mounting screws, and a strain-relief bracket for cable management. The accessory kit is not included with the SEHI, but can be purchased separately from Cabletron Systems using the part number SEHI-ACCY-KIT.

Rack mounting the SEHI involves the following:

Attaching the strain-relief bracket

Rack mounting the SEHI

Stacking the SEHI when applicable

Attaching the Strain-Relief Bracket

Attach the strain-relief bracket to the front of the SEHI as follows:

1.Locate the strain-relief bracket and four 8-32 x 3/8 inch screws from the SEHI-ACCY-KIT package.

Do NOT attempt to attach the strain-relief with screws other than the 8-32 x 3/8-inch screws included with the SEHI accessory kit. Use of longer screws may damage the unit or cause electrical shock.

2. Attach the strain-relief bracket to the bottom of the SEHI (Figure 4-3).
