Install short adapter brackets on the rear of a 23 inch wide rack to
accommodate the cable management brackets of a 21 inch wide
Passport 15000 or 20000.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• The short adapter brackets are included in switch hardware kits NTQS04
for a Passport 15000 or NTQH04 for a Passport 20000. To install short
adapter brackets, you need these parts:
— 12 left short adapter brackets (P0918823)
— 12 right short adapter brackets (P0918824)
— two thread-forming 10-mm (3/8-in.) hex-head screws per adapter
bracket (from a pack labelled P097F814)
1 See the figure "A short adapter bracket" (page 625). Hold a right bracket
so that:
• the center-hole at one end is at the top
• the edge with the paired holes that are covered on one side by a strip
of silvery grounding tape points away from you
2 At the rear of the rack, counting from the bottom of the right upright, locate
the 24th pair of holes. Mark their location on the inside of the upright.
3 Position the edge of the adapter bracket with the paired holes against the
24th pair of the upright. (The left brackets are for the left upright.)
4 Align the pairs of holes and loosely fasten a thread-forming 10-mm
(3/8-in.) hex-head screw through each of the holes.
5 Repeat to install a bracket at the 2nd and 11th hole-pairs below the newly
