He is being held in a segregated unit

Chauvin on Tuesday was taken to a state prison -- the Minnesota Correctional Facility-Oak Park Heights -- to await sentencing, Department of Corrections spokesperson Sarah Fitzgerald said.

The correctional facility is in Stillwater, about 25 miles east of downtown Minneapolis.

"He is on 'administrative segregation' status for his safety," Fitzgerald wrote to CNN in an email. "Administrative segregation is used when someone's presence in the general population is a safety concern."

He is at the prison through an agreement between the Hennepin County Sheriff's Office and the Minnesota Department of Corrections, Fitzgerald told CNN.

The judge will consider these factors

However, Chauvin has no prior criminal record. The state's guidelines say that for such a person, the presumptive sentence for both second-degree and third-degree murder is 12 1/2 years. The judge is given discretion to hand down a sentence between 10 years and eight months and 15 years for each.

Second-degree manslaughter carries a presumptive sentence of four years for someone with no record, according to the guidelines. The judge's discretion ranges from three years and five months to four years and eight months.

However, prosecutors are asking for a tougher sentence than the recommendations provide.

In two filings last year, prosecutors said five aggravating factors warrant an increased sentence. Those factors include that Floyd was particularly vulnerable, that he was treated with particular cruelty, and that children were present when the crimes were committed.

If the judge applies aggravating factors, it would shift Chauvin's sentence to a higher part of the legal range.

The sentences for all three crimes would likely be served at the same time, not consecutively. "Generally, when an offender is convicted of multiple current offenses... concurrent sentencing is presumptive," according to the guidelines.

What about the other officers charged?
