Installing a Shasta 5000 shelf assembly
Install a Shasta 5000 shelf assembly in a NEBS 2000 frame above a
Passport 15000 or 20000 to enable the interworking of VPN traffic.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• You need hardware kit with PEC NTHW85.
• You need two helpers capable of lifting and holding the Shasta 5000
(18-kg or 39 lbs without cards) until it is fastened to the adapter brackets.
Procedure steps
1 Separate and lay out the parts from the kit NTHW85.
2 On the silvery strip on the front surface of the left and right uprights, locate
the next available screw hole or dimple above each mounting ear of the
grill. Puncture each hole to mark where it is. For orientation, refer to the
figure “Location of shelf hardware for a Shasta 5000 in a NEBS 2000
frame” (page 502).
3 Move the Shasta 5000 shelf to the front of Passport 15000 or 20000
switch.
4 Have 2 helpers lift and position the Shasta 5000 above the grill and
between the uprights in the NEBS 2000 frame.
5 Carefully lower the shelf until the bottom adapter bracket holes align with
the marked holes on each upright.
6 Fasten a thread-forming 10-mm (3/8-in.) hex-head screw through the
bracket into each marked hole in the upright, then through each top hole
of the bracket into the upright. The top holes of the bracket align with the
first hole or dimple below the BIP’s mounting ear. Do not let go of the shelf
until the four screws are fully seated.
7 Fasten 14 more screws through the adapter brackets into the uprights, 7
per side. Space the screws apart leaving 3 empty holes. Tighten all
screws to snug plus a 1/4-turn.
8 Re-install the cable management brackets in their original positions.
9 Store the crate in case the shelf must be returned to the manufacturer.
