Chapter 6. 2220 FRU Exchange
Important
Almost all FRUs are hot pluggable and can be exchanged without powering OFF the 2220. Follow
carefully the procedure described.
Nevertheless if you need to power OFF the 2220-501 while the 2220-500 is active ensure that
the two switches have their "Set Switch Options" set in "Inhibit" state. (see “Nways Switch
Administration Station Windows Overview” on page 3-5).
Each time you change an FRU, carefully record its location and check that the attached cables
are correctly labeled.
The exchange procedures are documented with illustrations of ACDC type B, DC48 type B, and APC
type B: Howewer the procedures are identical for type A and type B units.
The differences between type A and type B units are shown in the following sections:
“Identify the ACDC Power Type” on page 6-19.
“Identify the DC48 Power Type” on page 6-20.
“Identify the APC Type” on page 6-21.
Note
The external front and rear covers of the machine are removed by pulling them out. The following
procedures assume that these covers have already been removed. Otherwise see “Opening The Doors
And Covers of 2220 Installed in 37 U Rack” on page 6-6. The front of the machine can be identified by
the location of the control panel.
