SCHEDULED MAINTENANCE: CWDC UPS Cutover to Generator Panel - 1140 SBCW

Start Time:           August 29, 2016 9:00AM

Projected End Time:   August 29, 2016 3:00PM

Service(s) Affected:
CECS servers, SAN2, DNS2, DHCP2, BACKUP, BACULA, CW-READYDATA, UMD-RADIUS2, UMD-RADIUS4, FIREWALL-CW (HA), WLC5520-CW (N+1), CHERRY (UM-Flint)

Service Type:         Production

Symptoms:             
Complete data center shutdown during the migration period


Comments:
In order to accommodate the migration of the Uninterruptible Power Supply (UPS) electrical circuits providing backup battery power to the CWDC (1140 SBCW) and 1131 SBCW network closet CWDC to the new SB generator(s), ITS will perform a complete shutdown of all systems and services originating from the CW Data Center (CWDC) in order to allow Facilities Operations and electrical contractors to safely conduct their work. At the conclusion of the electrical work and after ITS services have been restored, Facilities Operations will conduct a short duration load test as part of the final verification process to ensure that the generator can maintain a charge to the UPS batteries. ITS will provide updates during the process as time permits.

Comments:
In order to accommodate the migration of the Uninterruptible Power Supply (UPS) electrical circuits providing backup battery power to the CWDC (1140 SBCW) and 1131 SBCW network closet CWDC to the new SB generator(s), a roughly ten (10) minute disruption to wired and wireless network services will occur in the Science Building Computer Wing (SBCW), Kindergarten Module (KMOD), and AEC Construction Trailer. During the maintenance period, users can expect intermittent interruptions to wired and wireless networking as well as VoIP services provided by UM.
