TMLCMOUNT21
The TMLCMOUNT21 kit mounts Communication Rack Mount Servers to a 2-post, central office
type, 19-inch wide rack. This kit consists of L-shaped brackets that fasten to the sides of the
server and to the rack.

TMLPMOUNT41, TMLPMOUNT51 and TMLPMOUNT52
TMLPMOUNT41/51/52 series mounts Communication Rack Mount Servers to 2-post or 4-post
racks.
TMLPMOUNT41 and TMLPMOUNT51 are used for mounting servers on 19-inch wide racks.
These racks are considered standard EIA (universal hole spacing) racks.
TMLPMOUNT52 is used for mounting servers on 23-inch wide racks. These racks could be
standard EIA (universal or wide hole spacing) or ETSI (European) racks.
TMLPMOUNT41/51/52 series are designed with a slide-in rail-type system. Although the
mounts are designed as rails, they are not sliding rails. This means the servers can be slid into
the racks for installation purpose, but the rails are not designed to support a mounted server
during service.

Notes:
1. Extra care must be exercised with TMLPMOUNT41 to securely hold the server with one's hands
when sliding it out of the rack; otherwise, the server could fall to the ground as it is being removed.
2. Plastic strips on TMLPMOUNT41 have peeled off in some customer installations. The result of this is
that the parts are usable, but the server could have somewhat of a "scrape-in feel" rather than "slide
in". Also, the rails will fit sloppier, so the side-located chassis securing screws could be difficult to
align in 2-post installations. Replacement material is available from the plastic strip manufacturer.
3. Xylan is a tough, low-friction coating similar to Teflon.
4. EIA-Wide spacing doesn't have the interstitial hole that is present in EIA-Universal. TMLPMOUNT51
contains an adapter bracket to overcome this EIA-Wide issue.
5. This component (2U Nut Bar) enables installation of a rail kit into a 1U rack slot when there is already
equipment installed both above and below that open slot.
6. The sides of the server must be accessible when using TMLPMOUNT41 in 2-post racks.

can be adapted for a 2-post or 4-post installation.

The main difference between the TMLPMOUNT41 and TMLPMOUNT51/52 series is that the
TMLPMOUNT41 series uses a screw to lock the server in place using the Universal Mounting Bracket,
whilst the TMLPMOUNT51/52 series has an additional Slide Pull-Out Locking feature.

TMLPSLIDE01
The TMLPSLIDE01 is an accessory kit designed for use in conjunction with slide rails to
produce a rack mounted serviceable server. The TMLPSLIDE01 kit contains two Universal
Front Mounting Brackets that secure the server to the front of the rack. The sliding rails and
optional mounting brackets required to mount the server must be purchased through the
channel. For example, the Accuride 22-inch Model 305A-LR slide rails are designed to mount a
server for “in-rack service.” This example would also use an Accuride mounting bracket kit and
the TMLPSLIDE01.

Note: Using slide rails could result in non-compliance with Seismic Zone 4 requirements of
NEBS-3 certification.
