INSTALLATION

This chapter outlines the procedure for installing the SEHI to your network as a stackable or stand-alone device. Ensure that your network meets the guidelines and requirements outlined in Chapter 2, Installation Requirements/Speciﬁcations, before installing the SEHI.

3.1UNPACKING THE SEHI

Unpack the SEHI as follows:

1.Remove the shipping material covering the SEHI in the shipping box.

2.Carefully remove the SEHI from the shipping box and set it aside to prevent damage.

3.Visually inspect the SEHI. If there are any signs of damage, contact Cabletron Systems Technical Support immediately.

4.Read the SEHI Release Notes included in the shipping box.

Note: Cabletron Systems includes a 3-1/2" disk with the SEHI. This disk contains a backup copy of the SEHI’s Flash Firmware Image File. You can download the backup image file to the SEHI if the existing image becomes corrupted.

3.2INSTALLING THE SEHI

You can install the SEHI to your network as a stackable or stand-alone hub. If you want to install the SEHI on a wall or a 19-inch rack, Cabletron Systems offers an accessory kit that includes Rack Mount Brackets, Wall Mount Brackets, Mounting Screws, and a Strain Relief Bracket. The accessory kit is not included with the SEHI, but you can purchase it separately from Cabletron Systems as Part Number SEHI-ACCY-KIT.
