Installation of a MultiLink ML3000 Ethernet Switch in a 19-inch rack is a simple procedure.
The units are 1 U (1.75") high. When properly installed, the front-mounted LED status
indicators should be in plain view and easy to read. Rack-mount installation requires
special 19-inch rack-mounted brackets and screws (included with the ML3000). These
brackets attach to the front sides of the switch, which is then typically fastened on to a
standard 19" RETMA rack.
The 23" brackets and the ETSI (European metric, approximately 21") brackets are also
available (optional) for rack-mounting the ML3000 switches. These brackets are popular in
the telecommunications industry where they are a standard for Central Office rack-
mounting purposes. The 23" and the ETSI brackets are mainly used for larger equipment.
These brackets are rack-mounted in a frame typically accessed in operation from both
sides.
The bracket mounting holes in the sides of the Multilink ML3000 permits the installation of
all three types (19", ETSI, and 23") of available brackets.
The optional 23" brackets and the ETSI (21") brackets each come as a pair in a package,
along with the necessary screws for attaching the brackets to the sides of the ML3000
switch unit. They must be ordered as separate line items.
The optional Reverse ML3000 model has all of the cabling (ethernet cabling, power cabling
and console port cabling) connectors in the rear, and the status LEDs in the front. The
status LEDs that are co-incident with the ports are still present, and a second or dual set of
LEDs are used for status visibility in the front of the unit, showing the same data.
There are three options of brackets available to mount in the standard 19" frame, 23"
frame, or ETSI (21") frame. The 19" brackets are included with each unit; the other two may
be purchased as separate options.
The case of the ML3000 has mounting holes prepared for each of the mounting
arrangements. Users may choose the mounting arrangement most suitable for their
installation.
