Installing ARN Mounting Brackets
The flange brackets for mounting the ARN in a rack now support additional rack positions.
Figures 1-1 and 1-2 in
Installing and Operating BayStack ARN Routers
illustrate the
wrong mounting bracket. F
igure 1 correctly illustrates the options for attaching the new
mounting brackets.

Operation of Fan LED
Table 3-1 in
Installing and Operating BayStack ARN Routers
incorrectly describes the Fan
LED as an indicator of normal operation. The amber Fan LED actually indicates failure; it
lights if one or more cooling fan stops operating.
