Installation of a second switch into a NEBS 2000 frame
Install a second switch into a NEBS 2000 frame to maximize traffic capacity
for the same footprint area.

Prerequisites to installation of a second switch into a NEBS
2000 frame
• The switch in the bottom of the NEBS 2000 frame must be completely
installed. You can add the second switch without affecting the service.
• You need one of these switch hardware packages:
— NTQS10 for a Passport 15000
— NTQH10 for a Passport 20000
• If the NEBS 2000 frame that is to contain the added shelf has a door
mounted on its front, you need the key for the door lock from kit
NTQS37.
• To power the second switch, you can safely use the BIM pair for that
switch in either version of BIP. That is, you can use a pair of 25-amp
BIMs (AP6C67PA) of a Passport 20000 in a Passport 15000 BIP
(NT6C62). Or you can use a pair of 20-amp BIMs (NT6C60PA) of a
Passport 15000 in a Passport 20000 BIP (AP6C68). Each BIM pair must
be installed to power the appropriate Passport switch.
• Adding a second switch to a frame increases the cable density that is
supported by the cable management brackets on the frame. The total
number and type of FPs in the two switches can increase the cable
density such that you must use the extended cable management brackets.
Unless you planned for the brackets as described in 241-1501-205
Passport 15000, 20000 Site Requirements and Preparation Guide by
ensuring that there is enough space around the frame footprint or by
installing them according to the task flow “NEBS 2000 frame
installation” (page 161), you cannot add the brackets without moving the
frame.
