Prerequisites
Procedure steps
241-1501-240 5.2S2
Install sparing panel in a frame, rack, or cabinet to enable sparing
configuration as part of an initial installation or as part of a replacement.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• You may need to assemble the NTQS31 sparing panel prior to mounting.
See the procedure "Assembling sparing panel NTQS31" (page 249).
1 At the Passport 15000 or 20000 switch, unpack the sparing panel from its
container.
2 Orient the sparing panel as shown in the figure "A 12-port DS3 or E3 one-
for-six sparing panel NTQS31, fully assembled" (page 534).
3 With a helper holding an end of the new sparing panel with the connectors
facing into the frame and the standard coax connectors at the top, Place
the replacement panel against the mounting apparatus so that it aligns
with the appropriate mounting holes.
With the 12-port NTQS31, have a helper hold the panel in position for
fastening. The sparing panel has key-hole pins that align with the holes in
the frame.
4 While the helper continues to hold an end of the panel in position, fasten
a thread-forming 10-mm (3/8-in.) hex-head screw through the upper left
and the upper right mounting holes. Leave the screws close to being
seated.
5 Align the centers of the remaining mounting holes on the panel with the
holes on the mounting apparatus.
6 If the sparing panel is rack-mounted, fasten the grounding cable to the
panel where it was before.
7 Add the remaining fasteners, starting with a lower corner. Finger-tighten
all screws.
8 Tighten all screws to snug plus a 1/4 turn.
9 If you strip any of the fasteners
• with a 12-port 21-inch wide sparing panel NTQS31, you must use
one of the unused mounting holes or move the panel
