CHAPTER 3
Installation
This chapter outlines the procedure for installing the STHI. Confirm that
the network meets the guidelines and requirements outlined in Chapter 2,
Requirements & Specifications, before installing the STHI.
3.1 Installing the STHI
The STHI may be installed as a stand-alone hub or as part of a stack.
Provided with the STHI is an accessory kit that includes rack-mount
brackets for installations into 19 inch racks, wall-mount brackets and
mounting screws for installations on walls, and a strain relief bracket to
direct the stresses inflicted by cables hanging from the TCU ports.
All installations must meet the following requirements:
• A single phase 120Vac, 15A, grounded power receptacle must be
located within 7 feet of the STHI.
• Shelving units must be able to support 30 pounds of static weight for
each device in the stack. This accounts for both hub and cable weight.
• The ambient temperature must be maintained between -30° and 90°C
at all times and between 5° and 50°C during operation.
3.1.1 Unpacking the STHI
Unpack the STHI as follows:
1. Carefully remove the STHI from the shipping box, preserving the
packaging materials for future transport.
2. Visually inspect the STHI. If there are any signs of damage, contact
Cabletron Systems Technical Support immediately.
3. Read any Release Notes or Addendums included in the shipping box.
The package includes a 3-1/2” floppy disk containing a
backup copy of the STHI’s Flash Firmware Image File
which may be downloaded to the STHI if the original image
becomes corrupted.
